1973 • Electrodes are attached on both sides of the proton exchange membrane
• Proton exchange membrane is the electrolyte
• Proton exchange membrane acts as separator to prevent mixing
J. H. Russell released his works to
of the gas products

2 Executive Summary
EverWind Fuels LLC (“Ever Wind”) is a private developer of green hydrogen and ammonia
production, storage facilities and transportation assets. EverWind intends to expand and
develop the Point Tupper site to be the location of a regional green hydrogen hub for Eastern
Canada, including new green hydrogen and ammonia production facilities.
EverWind has requested KBR to perform a feasibility study to develop a Class-IV cost estimate
of a green ammonia plant for 600 MTPD capacity at Point Tupper site in Nova Scotia, Canada.
EverWind has engaged Hatch, a global multidisciplinary management, engineering, and
development consultancy, for supporting overall engineering design for this site.
EverWind has also engaged NEL, a global company providing solutions for the production,
storage, and distribution of hydrogen, for supplying Electrolysers and producing green
hydrogen for this site.
The purpose of this feasibility study is to analyse available technologies to apply to this
project that could provide an advantage and provide a cost estimate of Class-IV accuracy for
overall complex which includes Ammonia Synloop, Ammonia Storage (vendor), Air
Separation Unit (vendor) and integrated utilities.
KBR has experience in operating ammonia plants at low turndown ratio, approx. 30% for
several months in India. This real experience has helped KBR in developing a design for
flexible operation. Specifically, the synthesis loop can be operated between 10% to 110%.
This provides flexibility in operation in case of reduced hydrogen generation from
electrolyser due to power shortage.
KBR has developed the K-GreeN™ technology package, which consists of a fully integrated
solution from the electrolysis of water to produce green hydrogen, separation of air to
produce green nitrogen to the synthesis of green ammonia.
Ammonia production currently accounts for around 1.8% of global CO emissions with most
ammonia being produced from carbon-rich natural gas. With ammonia market rising as key
carrier source, it is imperative to move towards zero-CO emission process for a
sustainable future.
Green Ammonia is ammonia produced with no greenhouse emissions, it utilizes renewable
energy to separate Nitrogen from Air (through Air separation) and Hydrogen from water
(through electrolysis) which are then combined to form Ammonia in a well proven Haber
Bosch’s process.
Currently the main challenges in producing green ammonia are:
- The investment cost of the electrolysis system
- Small capacity modules of electrolyser resulting in large number of parallel modules
- Demand supply matrix is not clear due to large number of anticipated projects and
limited production capacity of stacks.
- The cost and intermittent availability of renewable electricity to operate the electrolysis
system.

Design Scheme
The scheme selected for this study features the following characteristics:
1. Green ammonia will be produced from green hydrogen, which will be generated via Water
Electrolysis with constant availability of renewable power (Not in KBR scope).
2. Hydrogen from Electrolyser will be available at 7 bar(g) and then sent to Synthesis gas
compression. Hydrogen will be supplied by EverWind, using NEL Electrolysers.
3. Nitrogen from ASU will also be available at 7 bar(g) and then sent to Synthesis gas
compression.
4. /N mixture in the synthesis gas compressor will be at the ratio of 3:1 and mix with the
unconverted recycle gas in the Recycle compressor.
5. Ammonia synthesis is based on KBR proprietary design including vertical converter, unitized
chiller, and converter catalyst.
6. The number of equipment in synloop is minimized by use of Unitized Chiller.
7. The loop allows generation of superheated steam which can be used for operating turbine.
Steam Turbine output is being used by Turbo-Generator to generate electrical power, to be
exported to grid in OSBL. The loop provides high flexibility with ramp rate changes at 1.5%
per minute.
8. The loop can also be turndown to very minimum capacity to 10% if needed which will help
in optimizing the hydrogen storage if needed.
9. Transfer of Product Ammonia at Ammonia Storage system.
The vendors were contacted, for few major items, to receive technical details and budgetary
costs, and for other items, KBR past references were being used, while the preliminary sizing
of equipment in the ammonia synthesis were carried out in-house for the basis of costing.
The utilities were integrated within the Ammonia ISBL to an extent possible to minimize
CAPEX.
Path Forward (For next step of Project)

This is a feasibility study, which defines the process scheme, main equipment being used,
typical feed and utilities required, product and effluent emissions from the plant. This study
also defines the preliminary sizing of equipment as well as costing at class IV level.
As a next step to this study, a basic engineering can be executed, and optimization study can
be part of basic engineering. The basic engineering can take 3-4 months. On the basis of the
basic engineering, Detail engineering or a FEED (Front End Engineering and Design) can be
executed to get the TIC (Total Installed Cost) or EPC cost with accuracy of ±10%. Execution of
FEED can take from 4-6 months’ time.
KBR can provide services of overall licensing of process and project management. KBR has
rich experience of project execution in challenging situations and well placed to support
EverWind in their future projects.

Ammonia Plant
KBR provides post BED services which helps in mitigating any risk in design and execution
especially with equipment. Because of KBR’s expertise in execution past EPC and detailed
engineering, KBR can also support detailed engineering wherever required. KBR provides
engineering package which is far more detailed than a standard process design package
which helps detailed engineering to move the project faster.
KBR can also offer a Digital Plant Control Suite, providing optimized design and reliable
operation through dynamic simulation model, Integrated Control System, Reliability,
Availability and Maintainability Analysis (Figure 1). This digitalization solution makes possible
to maximize the production of ammonia based on renewable power availability and minimize
the need for power and hydrogen storage.

3 K-GreeN™ Ammonia Technology Overview
3.1 Green Ammonia plant overview

KBR has developed this K-GreeN™ technology package which consists of a fully integrated
solution for the electrolysis of water, separation of air to produce green hydrogen and
nitrogen to the Haber-Bosch synthesis of green ammonia.
The KBR ammonia synthesis section is a proprietary design with proven unmatched reliability
and lower energy consumption at lower capital cost (due to lower equipment count).
In developing its K-GreeN™ concept, KBR has leveraged on its past 75+ years of experience
in designing ammonia plants, from very small capacity (~4 MTPD) to the largest single train
capacity (6,000 MTPD). Below figure provides a general overview of KBR Green Ammonia
offering.
The following figure exemplifies a preliminary block flow diagram for generic green ammonia
plants.
The core of each ammonia plant is the synthesis loop (“Synloop”), where hydrogen ( ) and
nitrogen ( ) are partially converted to ammonia ( ) according to the following
exothermic reaction:
+ 2
Since the conversion is equilibrium-limited, the unconverted reactants are separated from
the ammonia product and recycled back to the reactor after purging inert (such as argon), if
any.

Canada Page 7 of 80
Ammonia Plant
Synloops can be designed to operate at pressure in the range 100-300 bar depending on
several factors (such as type of catalyst, amount of inert introduced in the loop together with
the feedstocks, etc.). Higher pressure enhances the conversion but increases the investment
cost: 150 bar is the typical pressure at which KBR Ammonia Synloops operate, using
magnetite catalyst.
The ammonia converter, being the most critical equipment in the Synloop flow scheme, is
proprietary design of KBR.
The overall Synloop is optimized to meet specific site conditions and to reduce the CAPEX by
taking advantage of all possible synergies with other units as well as utilities and offsites
facilities
Advantages of process scheme:
 Well proven design
 reduced number and optimised design of the high-pressure equipment, which is the
most expensive part of the plant, and particularly the converter system and the
chilling system.
 KBR’s horizontal / vertical converter - design well-proven, having been used in more
than twenty KBR ammonia plants since 1983.
 Unitized Chiller - This equipment combines the feed/effluent exchanger, several
chillers, and the compressor knock-out drums into one equipment item.
 Steam Generation - Superheated steam generation making loop energy efficient
 No start-up boiler required
 Summary
o Reduced capital cost (capex) due to fewer pieces of equipment
o Reduced bulk equipment costs  lower capex
o Reduced construction cost  lower capex
o Reduced operating cost (opex) due to lower loop pressure drop
o Reduced maintenance cost associated with fewer pieces of equipment
o Robust and Reliable Steam Generation and Superheating with Process Gas
Feedstocks for the synthesis of green ammonia are:
 Hydrogen, generated from electrolysis of water by using renewable energy, such as
solar or wind or hydro power.
 Nitrogen, generated from separation of air, typically using a cryogenic system.
Within a green ammonia complex the greater energy consumer is the electrolysis system that
accounts for more than 90% of the overall power consumption.

Canada Page 8 of 80
Ammonia Plant
If electrolysers are driven by renewable power (solar) only, then storage of hydrogen is
necessary to allow continuous operation of the Synloop: unlike the electrolysers that can
operate on intermittent basis, Synloop, as well as Air Separation Unit (“ASU”) must run
continuously within an operating range, which is typically 30-100%.
By switching off the electrolysers when renewable power is not available, the power needed
of the complex is drastically reduced. Nevertheless, the complex needs to be connected to
the grid or alternate renewal source of energy to be able to maintain the Synloop and ASU in
operation constantly. Alternatively, renewable electric energy could be stored in batteries,
but that option is typically not economically viable for large quantity of energy.
Electrolysers could be operated using electric power from the grid when the renewable
power is not available. In such a case the cost of the power from the grid will also play an
important role in selecting the best configuration of the plant: if price rates of the power
from the grid vary over 24 hours, hydrogen storage should be designed to at least cover the
peak hour price rates.
Electrolysers operate at a pressure in a range between atmospheric, typical for the alkaline
type, to up to 30 bara, typical for polymer electrolyte membrane (“PEM”) type. The air
separation unit typically generate nitrogen at less than 10 bar. The synloop typically operate
at around 150 bara.
KBR can perform dynamic simulation of the synthesis loop to analyse various configurations
of the complex with the aim of:
 Studying the impact of intermittency of green hydrogen flow to the ammonia
synthesis and providing solution to minimise the impact of such disturbance to the
process.
 Identifying acceptable range of hydrogen flow variability within one-minute time
once flow is established.
 Assessing requirements in operation and control schemes for smooth operation of
the plant at various conditions.
 Defining the optimum pressure in hydrogen storage and recommended inventory
amount.
Thanks to its experience, capabilities and relationship with world-class electrolysers and ASU
suppliers, KBR can define the optimum configuration for the overall green ammonia complex,
integrating the Synloop with ASU, Electrolysers, and storages (Hydrogen, Nitrogen and/or
Ammonia) and generating significant synergies and savings.

3.2 Electrolysers
Hydrogen is produced from Electrolysis of water. Electrolysis essentially means “breakdown
(lysis) via electricity”. Electrolysis uses direct electric current to drive a chemical reaction, in
this case, H O is converted to hydrogen and oxygen. When the power used to drive the
process utilizes renewable power source like sun or wind, this process produces zero-carbon
hydrogen and oxygen. There are four main types of electrolysers available:
Alkaline Based
 Uses a liquid electrolyte solution such as potassium
hydroxide (KOH) or sodium hydroxide (NAOH), and
water (Figure 3-1).
 The hydrogen is produced in a “cell” which consists
of an anode, cathode, and membrane. These cells
are typically arranged in series in a “cell stack” to
generate more hydrogen and oxygen
 When current is applied on a cell stack, the
hydroxide ions move through electrolyte from the
cathode to the anode of each cell, with hydrogen gas
bubbles generated on cathode side of the Figure 3-1 Alkaline based electrolysis
electrolyser and oxygen gas at the anode as shown
in attached figure.
Proton Exchange Membrane (PEM)

 PEM electrolyzer use a Proton Exchange Membrane
which use a solid polymer electrolyte (Figure 3-2)
 When current is applied on a cell stack, the water splits
in hydrogen and oxygen and hydrogen protons pass
through the membrane to form H gas on the cathode
side.
 PEM provide high flexibility to meet the power
fluctuations from renewable energy. Figure 3-2 - PEM Electrolysis
Solid Oxide
 Solid Oxide electrolyser uses solid ceramic material
as the electrolyte (Figure 3-3)
 Electrons from the external circuit combine with
water as the cathode to form hydrogen gas and
negatively charge ions. Oxygen then passes through
the solid ceramic membrane and reacts at anode to
form oxygen gas and generate electrons for the
external circuit.
Figure 3-3- Solid Oxide Electrolysis

Canada Page 10 of 80
Ammonia Plant
AEM or Anion Exchange Membrane

 Anion Exchange Membrane (AEM) water
Electrolysers are considered one of the most
promising sustainable hydrogen production
technologies because of their ability to split water
using platinum group metal-free catalysts, less
expensive anode flow fields, and bipolar plates.
 One of the major advantages of AEM water
electrolysis is the replacement of noble
metal electrocatalysts with low cost transition
metal catalysts. This electrolysis type is still a
developing technology; therefore, with a view to
using it to eventually achieve commercially viable
hydrogen production, AEM electrolysis requires
further investigation and improvements. Figure 3-4- AEM Electrolysis
Alkaline based process, at least the “generation 2”, is a mature technology and has been in
market for 40+ years. As such, there is a very limited scope for potential improvements in the
technology in terms of efficiency and CAPEX. While Solid oxide Electrolysers have great
potential to become potentially more efficient than PEM and Alkaline, it is relatively new
technology and not proven at commercial level yet. New generation of alkaline technology
shows potential but are not commercially proven either. AEM or Anion Exchange Membrane
is in development with different scales of TRL (Technology Readiness).
PEM’s technology offers high efficiency. However, the CAPEX is currently higher than
Alkaline. Nonetheless, there is large potential for PEM technology to significantly reduce the
costs in coming future and becoming on the medium-term the most cost-effective.
Considering its efficiency, flexibility and operability, PEM seems the optimum solution for
large green ammonia plant in a the medium-term.

Ammonia Plant
3.3 Air Separation Unit (ASU)
Air separation unit (ASU) is a well-known proven process to make pure N 2 from air. The
Nitrogen Generation Plant utilizes the standard cryogenic distillation technology, which
enables the separation of air into its main components: nitrogen and waste gas (mixture of
nitrogen, oxygen, and argon). While the nitrogen is sent to the downstream process, waste
gas is used to regenerate the air purification device.
Process Description
Ambient air is filtered of particulate matter in the air suction filter and compressed in a
compressor. The compressed air then flows through a water separator to remove entrained
water. Heat from the compression will be removed in shell/tube heat exchanger.
Following the water separator, the air then feeds to one of two pre-purifier beds. Water
vapor, carbon dioxide, some nitrous oxide and some hydrocarbons in the air will be removed
in this section. While one bed is in service and is treating the feed air stream, the other bed
is undergoing regeneration by waste stream from cold box.
After passing through the bed, the air pass through a dust filter. Then it enters the cold box
where air will be separated into product nitrogen and waste gas. Product nitrogen from the
cold box will be compressed in a nitrogen compressor to required delivery pressure. Waste
gas from cold box will be used as regeneration gas for pre-purifier regeneration. In order to
transfer the required cold heat duty, the design requires that liquid nitrogen (LIN) will be
injected into the cold box as refrigeration agent to the cold box.

Ammonia Plant
N2 Storage
ASU unit shall have capability to produce Liquid Nitrogen. This liquid Nitrogen shall be stored
in tank for use as utility nitrogen during start-up and shutdown of Ammonia plant.
ASU plant design is well proven, and its running reference are available from small capacity
to large capacity. There is no major risk or challenge seen for ASU plant.

Ammonia Plant
3.4 Synthesis Loop
3.4.1 Ammonia Synthesis Overview
The process of the ammonia synthesis loop is based on KBR’s commercially proven synthesis
loop design. The ammonia synthesis loop is designed to produce cold ammonia with Syngas.
In normal operation, cold ammonia is sent to offsite atmospheric ammonia storage tanks at
-33°C. The Ammonia Synthesis unit shall be designed to operate between 10% to 100% of
nominal capacity.
Figure 3-5- Synloop Schematic Diagram
Synthesis Gas Compression

Raw material for green ammonia plants consists of hydrogen generated from electrolysers
and nitrogen generated from air separation unit.
Synthesis gas having hydrogen and nitrogen at ratio of 3:1 at pressure of 7 barg is compressed
to the synthesis loop pressure in the Synthesis Gas Compressor, which is a 5-stage centrifugal
compressor. Recycle gas from the synthesis loop is added to the make-up syngas before the
last wheel of the final casing, and then the mixed syngas is compressed to ~150.0 Bara in the
recycle wheel.
Ammonia Synthesis
Since make-up H2 & N2 gas contains no carbon oxides and water, which are poisons to the
synthesis catalyst (removal of oxygenated compounds in the hydrogen from electrolysers
might be required depending on electrolysis technology), it can be directly fed to the
converter, joining with the recycle or unconverted gas. Also, the make-up syngas has little
inert mainly Argon which provides a low inert synthesis loop with high partial pressure of
reactants H and N .
This process scheme has two advantages.
 First, refrigeration requirements will be lower than other schemes, in which the
moisture containing makeup gas is mixed with converter effluent to first pass
through the chilling train before going back to the converter.

Ammonia Plant
 Second, the ammonia converter capacity is increased because of lower ammonia
content in the feed because of mixing the ammonia free makeup gas with the recycle
gas. The low inert level in the makeup gas also permits operation of the synthesis
loop at lower pressures for a given level of refrigeration, saving syngas compressor
power.
The converter is a cold wall pressure vessel design where feed gas at relatively lower
temperature is passed through the annular space between basket and pressure vessel to
keep the pressure vessel cool, which makes the converter mechanically robust and cost
effective.
Ammonia is produced in a fixed-bed, horizontal / vertical converter. The converter is a three/
two thermodynamic stage, intercooled design.
Ammonia is synthesized by reaction of hydrogen and nitrogen:
3H + N 2NH + heat
The reaction takes place over the Fe based catalyst. The reaction is exothermic and is limited
by the chemical equilibrium, therefore only part of the hydrogen and nitrogen can be
converted into ammonia by passing through the catalyst bed. The chemical equilibrium, or
ammonia formation, is favour by high pressure and low temperature. However, the reaction
velocity is enhanced by high temperature. Therefore, there is optimum inlet temperature for
each bed at which the maximum ammonia conversion can be obtained per pass. Two built-
in heat exchangers and facilities are provided for bed inlet temperature optimization.
The ammonia concentration in the effluent gas exiting last bed reaches about ~18 - 19 molar
percent due to synthesis reaction over the catalyst. The converter effluent then enters the
MP steam boiler/superheater, where MP steam is generated & superheated at a pressure of
45.5 Barg and 370°C which is then utilized in generating electrical power in turbogenerator.
The converter effluent gas is further cooled and condensed in the Ammonia Unitized Chiller.
This specially designed exchanger provides cooling of the converter effluent through
interchange of heat with synthesis gas returning from the Ammonia Separator, and boiling
ammonia liquid at two different temperature levels.

Ammonia Plant
Liquid ammonia product disengaged from the synthesis gas in Ammonia separator
immediately downstream of the exchanger and it is depressurized and flashed into Ammonia
let-down drum. The liquid ammonia product from let-down drum is sent to first stage
refrigerant flash drum & the ammonia Refrigerant Receiver.
The inert quantity in feed is very less, hence there is no requirement of purge gas from
synthesis loop.
The remaining vapor from Ammonia separator is reheated in the unitized chiller as described
above and routed back to the synthesis gas compressor, where it is mixed with the fresh
makeup syngas and compressed in the final stage of the compressor.
Ammonia Refrigeration
A three-stage ammonia refrigeration system is provided for condensation of the ammonia
produced in the converter.
The converter effluent is chilled and condensed in the unitized chiller by using two levels of
ammonia refrigerant. Vapor from the shell side compartments of flash drums are routed to
second, & third stage of Ammonia Refrigerant Compressor respectively. Production of -
33.0°C cold ammonia liquid product is accomplished by flashing the ammonia liquids from
first level of unitized chiller to ammonia atmospheric flash drum. The flashed vapor from
atmospheric flash drum is routed to first stage suction of Ammonia Refrigeration
Compressor. The compressed ammonia vapor is ultimately condensed in the refrigerant
condenser. The condensed ammonia from condenser goes to the refrigerant receiver.
Liquid ammonia from bottom of refrigerant receiver is routed to second stage refrigerant
flash drum and used as refrigerant.
Cold ammonia liquid product at -33.0°C from ammonia atmospheric flash drum is pumped
by Cold ammonia pump and sent to the ammonia storage tank.
Start-up Heater
An Electrical Start-up Heater is provided for preheating ammonia synthesis gas for ammonia
converter catalyst reduction and for normal plant start up. Normally the start-up heater is
idle at full load.
KBR’s superior process design is complemented with several outstanding mechanical design
features. They are discussed in the following paragraphs.
3.4.2 Key Equipment Features
Synthesis Converter
KBR has wide portfolio of ammonia converters for both Horizontal and Vertical
configurations. For the small capacities, KBR uses vertical converter design. The converter
has been designed to achieve a high conversion of ammonia with very low pressure drop.

Ammonia Plant
Figure 3-6- KBR Horizontal Ammonia Converter
The converter contains a removable catalyst basket within the pressure shell. The converter
is designed so that the internal catalyst basket and intercoolers can be removed from the
pressure shell through a flanged opening on one end of the reactor.
The converter is intercooled and has two or three equilibrium stages. Integral with the basket
are the one / two intercoolers. An annular space exists between the cylindrical catalyst basket
and the high-pressure shell to provide a path for feed gas cooling the shell.
The converter primarily uses 1.5 to 3 mm size promoted magnetite-based catalyst. The
catalyst volume is chosen for end of the life conditions (typical 20 years). Each catalyst bed
is supported on Profile Wire Screens. The process flow is downwards through each bed. All
the feed gas passes through each of the catalyst beds.

Ammonia Plant
Unitized Chiller
The Unitized Chiller is a specially designed, multi-stream heat exchanger that cools the
effluent from the ammonia synthesis converter with recycle gas and with boiling ammonia
refrigerant at several temperatures. In doing so, the Unitized Chiller combines several heat
exchangers, compressor knock-out drums, and expensive high-pressure piping and fittings
into one piece of equipment. This design saves pressure drop in the synthesis loop and
reduces capital cost.
The basic concept of the Unitized Chiller is the use of concentric tubes and a
compartmentalized shell to replace several equipment items with one. The converter
effluent flows through the annuli of the concentric tubes, and the recycle gas flows through
the inner tubes. Refrigeration ammonia at various temperatures boils on the shell side in
several compartments. Thus, the converter effluent is simultaneously cooled by two media,
the recycle gas and ammonia refrigerant.

KBR Unitized Chiller

Converter Effluent Steam Generator

Well proven KBR’s heat exchanger design with removable U tube bundle having tubesheet at
the cold end is used for generating MP steam using high grade waste heat in the converter
outlet syngas. This exchanger, engineered for the specific process conditions at the ammonia
converter outlet, is highly robust and reliable and has been used in KBR plants. This has
proven to be more reliable than boilers with integral drum and fixed tubesheet.
Turndown Capability
Turndown operation of ammonia synthesis loop is important when the renewable energy is
not available. To minimize the requirement of hydrogen storage, it is required to turn down
the operation of ammonia plant. Synloop has been designed to be able to operate with a
minimum turndown ratio to cope with the variable availability of hydrogen generated. Some
key features of that design are:
 KBR proven design for operation range from 30% to 100%. Lower turndown is also
possible
 Electric heater with fast operation employed to prevent loss of reaction in ammonia
converter during ramp-up / ramp-down.
 As long as the design conditions of material are not exceeded, minimal impact on plant
integrity is expected.
 It is possible to operate the Ammonia plant within an operating range of 30 to 110%.
However, not all pieces of equipment can be turn-downed to 30%. In particular, most of
rotary equipment operate at a minimum turn-down of 70-80%, hence power
consumption cannot be reduced proportionally to the capacity, unless redundant pieces

Ammonia Plant
of equipment are installed, e.g., two parallel compressors, each for half capacity, instead
of a single full capacity item.
 In addition, for capacities below 60-70%, start-up heater shall be started to provide
adequate heat to sustain reaction in the Ammonia converter, depending upon the
operating pressure. Therefore, when capacity of ammonia plant reduces below 60-70%,
the specific power consumption of Ammonia plant starts increasing to account for
power consumption of start-up heater. However, the plant can be turndown to 20%
without significant drop in loop pressure and hence 102-B requirement can be avoided
 Similarly, power consumption in Air Separation Unit (ASU) and utilities are not reduced
in proportion to Ammonia plant capacity.
 On the other hand, Electrolyser tend to operate more efficiently as capacity reduces.
From 100% to 20% capacity, the energy consumption reduces. Taking into consideration
that most of the overall power consumed in a green ammonia plant is due to the
electrolyser, the increase of electrolyser efficiency at lower capacity can partially or
entirely offset the reduced efficiency of the ASU and ammonia synthesis at reduced
capacity.
 It is important that plant load should be increased or decreased at fast rate as per
availability of H2 from Electrolyser based on renewable power. Synloop plant load can
be increased or decreased from 30% to 100% or 100% to 30% in 1 hours.
 Power profile availability provides insight on requirement of turndown operation and
hydrogen storage. Electrolysers provide flexibility for faster ramp and ramp down and
start and stop feature with hot stand-by.
 Ammonia plant and ASU does not provide that flexibility and can not start and stop in
short time. Therefore, these units need to be operated all time at minimum turndown
capacities.
 For operating the ammonia and ASU plant when renewable energy is not available,
Hydrogen storage and battery storage or grid back-up may be required.

Ammonia Plant
3.5 Ammonia Storage
Refrigerated ammonia storage tanks, with required capacity, are considered at the site to
store cold ammonia production at full capacity from the Ammonia Plant. The Ammonia
Storage Tanks normally a dome roof, double wall double integrity storage tank and it
operates at positive pressure ie 300mmwc. The ammonia storage tanks are protected from
overpressure or vacuum by pressure/vacuum relief valves.
Transfer of ammonia from the storage tanks to Ship are performed by two Liquid Ammonia
Transfer Pumps, one operating and one standby.
Ammonia Vapor Recovery
Ammonia vapor are generated due to:
- Heat leak into the refrigerated tanks and cold ammonia piping.
- Vapor displacement in tank/ rundown / unloading
- Flash during Ammonia transfer.
During Normal operation, the vapor generated will travel to Ammonia plant and will be
compressed and condensed in Ammonia refrigeration system. Condensed Ammonia will be
transferred back to the storage tank If the pressure in Ammonia Storage Tanks continues rise,
the Ammonia Storage Refrigeration Package, 2100-L will be started automatically. Vapor will
be condensed, subcooled in 2100-L and returned as liquid ammonia to the storage tanks.
Ammonia Storage Flare
The Ammonia Storage Flare system consists of the Ammonia Storage Flare KO Drum, a Flame
Front Generator, and the Ammonia Storage Flare.
The Ammonia Storage Flare System is provided for safe incineration of ammonia vapors, in
the event of Ammonia Storage Refrigeration Package is not available. Ammonia vented /
discharged from low pressure equipments (such as ammonia storage tanks) and pipings is
sent to Ammonia Storage Flare.
Risk and Challenges –
The double wall atmospheric ammonia storage tanks are well proven method of ammonia
storage. The tanks with double integrity walls provide minimum risk of ammonia leakage and
widely acceptable method of ammonia storage.
The tanks are available for higher storage capacities and does not have any risk of scale-up.

Process Description-Normal operation
The process of the ammonia synthesis loop is based on KBR’s commercially proven synthesis
loop design. The ammonia synthesis loop is designed to produce 600 MTPD Cold ammonia with
Syngas. In normal operation, cold ammonia is sent to offsite atmospheric ammonia storage tanks
at -33°C. The Ammonia Synthesis unit shall be designed to operate between 30 to 105% of
nominal capacity.
All the components of the ammonia synloop are based on well proven technology features. The
synthesis gas compressor and the ammonia refrigerant compressor are motor driven. All other
pumps/machines also have motor as drivers.
The process design flow and conditions for the normal end of run (EOR) condition at the Cold
ammonia product temperature of -33°C is illustrated on the process flow diagram drawings of FD-
1, FD-2 & FD-3.
The process is described in the following sections:

• Air Separation Unit
• Synthesis Gas Compression
• Ammonia Synthesis
• Ammonia Refrigeration
• Startup Heater
• Ammonia Storage
• Utility System
Air Separation Unit
Air separation unit (ASU) is a well-known proven process to make pure N2 from air. The Nitrogen
Generation Plant utilizes the standard cryogenic distillation technology, which enables the
separation of air into its main components: nitrogen and waste gas (mixture of nitrogen, oxygen,
and argon). While the nitrogen is sent to the downstream process, waste gas is used to regenerate
the air purification device.
Ambient air is filtered of particulate matter in the air suction filter and compressed in a compressor.
The compressed air then flows through a water separator to remove entrained water. Heat from
the compression will be removed in shell/tube heat exchanger.
Following the water separator, the air then feeds to one of two pre-purifier beds. Water vapor,
carbon dioxide, some nitrous oxide and some hydrocarbons in the air will be removed in this
section. While one bed is in service and is treating the feed air stream, the other bed is undergoing
regeneration by waste stream from cold box.
After passing through the bed, the air pass through a dust filter. Then it enters the cold box where
air will be separated into product nitrogen and waste gas. Waste gas from cold box will be used
as regeneration gas for pre-purifier regeneration.
ASU shall have the capability to produce liquid Nitrogen. This liquid nitrogen shall be stored in
tank for use as utility nitrogen during start-up and shut down of Ammonia Plant.

Page 3 of 9
Synthesis Gas Compression
Synthesis gas having hydrogen and nitrogen at ratio of 3:1 at pressure of 8 bar is compressed to
the synthesis loop pressure in the Synthesis Gas Compressor, 103-J, which is a 5-stage
centrifugal compressor. In the first four stages along with its intercoolers, the gas is compressed
to around 143.5 Bara. Recycle gas from the synthesis loop is added to the make-up syngas before
the last wheel of the final casing, and then the mixed syngas is compressed to 150.0 Bara in the
recycle wheel.
Anti-surge system is provided to protect the machine during start-up and turndown operations to
allow cooled discharge and or recycle gases be spilled back to the suctions of each stage to
prevent the compressor from going into surge. Normally all the anti-surge valves should be closed
though.
The compressor is driven by a motor, 103-JM, equipped with VFD (Variable Frequency drive) to
minimize power consumption at reduced loads.
Ammonia Synthesis
Ammonia is produced in a fixed-bed, vertical Ammonia Synthesis Converter, 105-D. The

converter is a two thermodynamic stage, intercooled design. Each bed is filled with 1.5-3 mm
iron promoted synthesis catalyst. The first bed (and optionally the other) will be filled with pre-
reduced catalyst.
The converter is a cold wall pressure vessel design where feed gas at relatively lower temperature
is passed through the annular space between basket and pressure vessel to keep the pressure
vessel cool, which makes the converter mechanically robust and cost effective. 105-D contains a
removable basket, which includes two fixed-beds of catalyst and one built-in heat exchanger. The
gas flow pattern in 105-D is arranged such that all the synthesis gas passes through all the
catalyst. This results in maximum conversion.
Make-up and recycle gas from the syngas compressor is preheated to about 236°C by heat
exchange with the converter effluent in the Converter Feed / Effluent Exchanger, 121-C before
going to the converter. Ammonia concentration in the feed to the converter is about 3.84 molar
percent.
Ammonia is synthesized by reaction of hydrogen and nitrogen:

3H2 + N2 2NH3 + heat
The reaction takes place over the Fe based catalyst. The reaction is exothermic and is limited by
the chemical equilibrium, therefore only part of the hydrogen and nitrogen can be converted into
ammonia by passing through the catalyst bed. The chemical equilibrium, or ammonia formation,
is favored by high pressure and low temperature. However, the reaction velocity is enhanced by
high temperature. Therefore, there is optimum inlet temperature for each bed at which the
maximum ammonia conversion can be obtained per pass. One built-in heat exchanger and
hot/cold shot facilities are provided for bed inlet temperature optimization.

Page 4 of 9
Before entering converter, the feed gas from 121-C is split into two streams. The feed stream
passes through the annulus of 105-D, cooling the outer shell and is then preheated against 1st
bed effluent in the Ammonia Converter Bed 1 Interchanger, 122-C. The second stream
(normally no flow) is not preheated and is fed directly to the inlet of 1st bed to control the inlet
temperature. The two streams are mixed, and the total gas passes through catalyst in the 1 st
bed.
By adjusting the two-way split of converter feed to 105-D and by adjusting BFW flow and bypass
around the Converter effluent/BFW Preheater exchanger 123-C3, the inlet temperature to each
of the beds can be individually controlled.
The ammonia concentration in the effluent gas exiting last bed reaches about 18.5 molar percent
due to synthesis reaction over the catalyst. The converter effluent then enters the 123-C1/C2
where MP steam is generated & superheated at a pressure of 44.9 Barg and 370°C which is then
utilized in generating electrical power in Turbo-Generator, 301-JG through Steam Turbine for 301-
JT.
The converter effluent then enters the 123-C3 where heat is recovered to preheat BFW water.
The converter effluent is cooled to about 262°C in these exchangers. Converter effluent is further
cooled to 80°C by heat exchange with converter feed from the syngas compressor discharge in
the Ammonia Converter Feed/Effluent Exchanger, 121C.
The converter effluent from 121-C is then cooled to about 29°C by cooling water in the Ammonia
Converter Effluent Cooler, 124-C. Because of the high conversion obtained in 105-D, the dew
point of the converter effluent is above the outlet temperature of 124-C. This causes the
condensation of ammonia to start in 124-C and saves refrigeration duty downstream.
The converter effluent gas is further cooled and condensed in the Ammonia Unitized Chiller, 120-
C. This specially designed exchanger provides cooling of the converter effluent through
interchange of heat with synthesis gas returning from the Ammonia Separator, 146-D, and boiling
ammonia liquid at two different temperature levels (14.7ºC and -6.1ºC). By its unitized design, it
replaces two separate exchangers, two refrigerant drums, feed/effluent exchangers, and the
interconnecting piping.
Mechanically, the 120-C consists of multiple concentric tubes, which run through the boiling
ammonia compartments. Synthesis gas recycle vapors from the downstream Primary Separator,
146-D, pass through the center tubes counter currently to the converter effluent as it flows through
the annular space between tubes. Thus, the synthesis gas is being cooled from the larger outside
tube by boiling ammonia and from the inside tube by cold recycle vapor from the primary
separator. The condensed gas exit temperature of the unitized chiller is 0ºC, with the liquid
ammonia product disengaged from the synthesis gas in 146-D immediately downstream of the
exchanger.
The inert quantity in feed is very less, hence there is no requirement of purge gas from synthesis
loop.

Page 5 of 9
The remaining vapor from 146-D, containing approximately 5.06 mol% ammonia, is reheated in
the unitized chiller to about 33°C as described above and routed back to the synthesis gas
compressor, where it is mixed with the fresh makeup syngas and compressed in the final stage
of the compressor.
Liquid ammonia from 146-D is depressurized and flashed to a pressure of 15 Bara in 147-D. The
liquid ammonia product from 147-D is sent to 120-CF1 & the ammonia Refrigerant Receiver, 149-
D. 147-D overhead flashed vapor, primarily contains dissolved synthesis gas, is recycled back to
the syngas compressor suction.
Ammonia Refrigeration
A three-stage ammonia refrigeration system is provided for condensation of the ammonia

produced in the converter.
The refrigeration system consists of a 3-stage centrifugal compressor, 105-J driven by electric
motor 105-JM, equipped with VFD (Variable Frequency Drive) to minimize power consumption at
reduced loads, along with:
• Refrigerant Compressor Intercooler, 128-C

• Refrigerant Condenser, 127-C
• Refrigerant Receiver, 149-D
• Refrigerant drums: First Stage Refrigerant Flash Drum, 120-CF1, Second Stage
Refrigerant Flash Drum, 120-CF2, and Ammonia Atmospheric Flash Drum, 152-D.
As previously described, the converter effluent is chilled and condensed in the unitized chiller
120-C by using two levels of ammonia refrigerant. Vapors from the shell side compartments of
120-CF1 & 120-CF2 are routed to second & third stage of Ammonia Refrigerant Compressor 105-
J respectively. The ammonia vapor is ultimately compressed to about 12.98 Bara and condensed
by cooling water in the refrigerant condenser, 127-C. The condensed ammonia from 127-C goes
to the refrigerant receiver 149-D.
149-D receives condensed ammonia from 127-C at 30°C. A part of Cold ammonia liquid from the
ammonia letdown drum 147-D is used in stripping section of 149-D, rest is sent to 120-CF1.
Liquid ammonia from bottom of 149-D is routed to 120-CF2 and used as refrigerant.
The small amount of non-condensable gas in the ammonia accumulator goes to OSBL / Flare.
Production of -33.0°C cold ammonia liquid product is accomplished by flashing the ammonia
liquids from 120-C cold compartment (120-CF1) to atmospheric pressure in the atmospheric
ammonia flash drum, 152-D. The flashed vapor from 152-D is compressed by the ammonia
Refrigeration compressor 105-J first stage. Cold ammonia liquid product from 152-D is pumped
by Cold ammonia pump 124-J/JA and sent to the Ammonia Storage Tanks, 2100-F/FA.

Page 6 of 9
The ammonia refrigeration system is designed to produce all cold ammonia product at the 600
MTPD design capacity as well as compress 1000 kg/h of BOG from storage.
Start-up Heater
An Electrical Start-up Heater, 102-B, is provided for preheating ammonia synthesis gas for
ammonia converter catalyst reduction and for normal plant start up. Normally the startup heater
is idle at full load.
A fresh charge of ammonia synthesis catalyst needs to be activated or reduced. The gas is
circulated through the synthesis loop by 103-J and is heated up in Startup Heater 102-B. The
conditions in the converter are controlled carefully to obtain a proper heating and reduction rate
of the catalyst. The catalyst beds are reduced in sequence. The reduction generates water, which
is separated in 146-D. To reduce the time needed for catalyst reduction, the converter bed #1 is
charged with pre-reduced catalyst.
102-B is also used during subsequent plant start-ups, to heat the catalyst in the converter to a
temperature where the synthesis reaction is self-sustaining.
For capacities below 70%, start-up heater shall be started to provide adequate heat to sustain
reaction in the Ammonia converter depending upon the operating pressure. However, the plant
can be turndown to 20% without significantly reducing the loop pressure. This avoids use of start
heater and also avoids fatigue stresses to equipments.
Ammonia Storage
Two Ammonia storage tanks, 2100-F/FA, with capacity of 28,000 MT, are considered at the site
to store cold ammonia production at full capacity i.e., 600 MTPD for around 65 days, considering
maximum tank filling capacity as 70%.
The Ammonia Storage Tanks will be a done roof, double wall double integrity storage tank and it
operates at slightly positive pressure, i.e., 300 mmwc. The ammonia storage tanks will be
protected from overpressure or vacuum by pressure / vacuum relief valves.
The double wall atmospheric ammonia storage tanks are well proven method of ammonia
storage. The tanks with double integrity walls provide minimum risk of ammonia leakage and
widely acceptable method of ammonia storage.
Transfer of ammonia from the storage tanks to Ship will be performed by two liquid Ammonia
Transfer Pumps, 2101-J/JA, one operating and one standby.
Ammonia vapors are generated from storage mainly due to:

- Heat leak into the refrigerated tanks and cold ammonia piping
- Vapor displacement in tank / rundown / unloading
- Flash during ammonia transfer

Page 7 of 9
During Normal operation, the vapor generated will travel to Ammonia plant and will be
compressed and condensed in Ammonia Refrigeration system. Condensed ammonia will be
transferred back to storage tank. If the pressure in Ammonia Storage Tanks continues rise, the
Ammonia Storage Refrigeration Package, 2100-L will be started automatically. Vapor will be
condensed, subcooled in 2100-L and returned as liquid ammonia to the storage tanks.
The Ammonia Storage Flare system consists of the Ammonia Storage Flare KO Drum, 5105-D,
a Flame Front Generator and Ammonia Storage Flare, 5102-L.
The Ammonia Storage Flare is provided for safe incineration of ammonia vapors, in the event of
Ammonia Storage Refrigeration Package is not available. Ammonia vented / discharged from low
pressure equipment (such as ammonia storage tanks) and piping is sent to Ammonia Storage
Flare.
Utility Systems
Steam:
The steam system is shown on steam balance flow diagram FD-2
The header conditions are:
Pressure Temperature
(Barg) (ºF)
Medium Pressure (MP) Steam Header 44.9 370
Low Pressure (LP) Steam (Blowdown Flash) 3.0 198
MP steam is generated by recovering waste heat from ammonia converter effluent in series of
exchanger 123-C1/C2/C3. MP steam is generated in Ammonia converter effluent / MP steam
generator,123-C2 at 45.4 Barg and 259°C. Saturated steam produced is then superheated to
370°C in Ammonia converter effluent / MP steam superheater, 123-C1 (integral with 123-C2).
The superheated steam is then used to generate power in Turbo-Generator 301-JG, through
Steam Turbine, 301-JT. Approximately 4093 kW of power is generated. The generator is driven
in MP-condensing steam turbine. The exhaust steam from turbine is condensed in surface
condenser 301-JTC and condensed steam in sent back to polisher unit for using back as demin
water.
The above scheme is provided, as there is no steam export from the Ammonia plant.
Blowdown from 123-C2 goes to MP steam Blowdown drum, 186-D. A very small amount of LP
steam is generated because of flash in 186-D which is sent to LP Steam Header and 186-D
bottoms is exported to OSBL.
Polished / DMW water from the Polisher Unit Storage Tank flows to the Deaerator, 101-U. The
deaerator pressure is maintained at 1.7 Barg, which results in a saturation temperature of 130 ºC.
The de-aerated water or Boiler Feed Water is pumped by a motor driven Boiler Feed Water Pump,
104-J, and is preheated in 123-C3 to about 250ºC and goes to 123-C2 for steam generation.

Page 8 of 9
Different Chemicals are added in 101-U to achieve Boiler Feed Water Quality.
Cooling water:
The cooling water system is shown in FD-3. Cooling water is supplied to the battery limit at
temperature of 24°C and pressure of 4.5 Barg. To lower cooling water usage, the surface
condensers, 301-JTC, operate in series with the Ammonia Condenser, 127-C. Open cooling tower
system is assumed taking fresh make-up from potable water.
Turndown Operation
The Ammonia Unit is designed for 30% turndown capacity without any effect on equipment.
However, not all pieces of equipment can be turn-downed to 30% and most of rotary equipment
operate at minimum turn-down of 70-80% and hence their specific consumption is more al lower
synthesis loop capacity.
For example, a centrifugal compressor can be reduced to the capacity without energy penalty
only till the operating point is above the surge line. Below this point, the gas needs to be recycled
back and power consumption of compressor does not reduce with capacity and rather remains
constant.
Similarly, power consumption in Air Separation Unit (ASU) is mainly for Air compressor.
Therefore, turndown of air compressor is limited and turndown below 70% consumes similar
power. With use of new schemes from vendor, the power consumption can be optimized such as
by using two parallel air compressors.
The utility requirement like cooling water remains same as for normal capacity as cooling water
flow is not reduced during turndown operation.

13 Operational scenario for Green Ammonia Complex
Power Consumption with change in Ammonia capacity
It is possible to operate the Ammonia plant withing a range of 30 to 100% and even lower.
However, not all pieces of equipment can be turn-downed to 30% and most of rotary
equipment operate at minimum turn-down of 70-80% and hence their specific consumption
is more al lower synthesis loop capacity.
For example, a centrifugal compressor can be reduced to the capacity without energy penalty
only till the operating point is above the surge line. Below this point, the gas needs to be
recycled back and power consumption of compressor does not reduce with capacity and
rather remains constant.
In addition, for capacities below 70%, start-up heater shall be started to provide adequate
heat to sustain reaction in the Ammonia converter depending upon the operating pressure.
The plant can be turndown to 20% without significantly reducing the loop pressure. This
avoids use of start heater and also avoids fatigue stresses to the equipment.
Similarly, power consumption in Air Separation Unit (ASU) is mainly for Air compressor.
Therefore, turndown of air compressor is limited and turndown below 70% consumes similar
power. With use of new schemes from vendor, the power consumption can be optimized
such as by using two parallel air compressors.
The utility requirement like cooling water remains same as for normal capacity as cooling
water flow is not reduced during turndown operation.
Below curve provides estimate of power consumption for ammonia ISBL with change in
capacity. The power consumptions at turndown does not reduces linearly with capacity and
increases below 70% of plant load. This is because compressors with anti-surge open, so the
power consumption does not reduce linearly with capacity and end up in approx. 85% of
normal power consumption at 20% turndown capacity. Additionally with lower capacity,
steam generation equally reduces, however, the efficiency of turbo-generator at lower
capacity reduces leading to further reduction in power generated. The final figures depend
on compressor and turbo generator selection.

14 Cost Estimation
Class-IV estimate cost (+/- 40% Non-binding of Total Installed Cost) is based on grass-root
installation of full Green Ammonia complex, which includes following units- Ammonia
Synloop, Air Separation Unit (ASU) and Ammonia storage along with its associated items i.e.,
Boil-Off Gas Refrigeration package, Ammonia Transfer Pumps and Ammonia Storage Tank
Flare. In addition to cost estimate below, a Licence fees of approx. 1.65 MillionUSD$ need to
be added for one-time payment. 1

Total Installed Cost (TIC) $ 212,430 $ 19,829 $ 121,219
The preliminary overall Non-Binding price of long lead items is 67 Million USD$ (includes
PEQs, Compressors, ASU and Ammonia Storage). 1
To be noted that, during the execution of the study, budget quotations have been obtained
for all major pieces of equipment. Therefore, the cost estimate has been prepared on the
basis of the current prices’ level of equipment (Q2-2022).
Due to the present volatility of the market and supply chain disruptions, we have noted that
vendors provide quotations for equipment as high as 50%-80% higher than in 2021. Since the
TIC estimate is factored based on equipment price, this inflated price is cascaded to the bulk
materials, installation, and construction. In reality, the cost of bulk materials as well as the
cost of installation and construction might not be experiencing the same level of inflation.
Moreover, the market situation might be significantly better in the coming year.
Only a more accurate and detailed assessment (FEED) can provide more certainty, which is
the recommended path forward for the project.

15 Preliminary Project Schedule

Tentatively, Basic Engineering Design phase schedule will be for 16 to 18 weeks and lead time

16 KBR experience
Since 1943 KBR has designed and licensed a total of 268 grassroot syngas, hydrogen and/or
ammonia plants. Out of 268 plants:
 255 include syngas (hydrogen and carbon monoxide) generation from hydrocarbon
reforming.
 250 include ammonia production.
 13 are standalone ammonia synthesis plant (“Synloop”) based on hydrogen and
nitrogen available from sources other than hydrocarbon reforming, such as carbon
neutral hydrogen from carbon black production, refinery off-gases, coal gasification, etc.
Over the years, KBR has been in the forefront to introduce technology innovations supported
by sound equipment design concepts to achieve economies of scale, energy efficiencies and
other critical operational records on-stream, reliability, safety, and environmental
performances.
Introduction of centrifugal compressor by KBR in 1960s paved way for a major shift in the
development of syngas and ammonia technology. With a persistent mind to stretch the
bounds, KBR has introduced several enhancements to the syngas and ammonia process
technology to help industry reaching new milestones.
Some of the notable milestones are listed below:
 1943 KBR Licensed first unit
 1960s Centrifugal compressor in synloop
 1960s Cryogenic Purifier for Syngas
 1970s SMR-Gas Turbine (GT) integration
 1980s “Mega” SMR in operation (936 tubes) – for a methanol plant

Ammonia Plant
 1990s KBR Reforming Exchanging System (KRESTM)
 1990s KAAP Ammonia Synthesis
 1990s ATR with Enriched air for ammonia production
 2010s High Pressure Reforming for Syngas production
Some highlights of recent achievements include:
 The most energy efficiency ammonia plant in the world is based on KBR technology (6.27 Gcal/ton,
Chambal, India).
 The largest ammonia plant with a single converter operating worldwide is based on KBR technology
(3,000MTD, EuroChem, Russia).
 The most reliable ammonia plant worldwide is based on KBR technology (2,162 consecutive days of
operation, almost 6 years, at Yara, Netherland).
With reference to design special challenges, in 2020 KBR completed the design of Monolith
Olive Creek, Nebraska, USA Ammonia Synloop with a capacity of 930 MTD. This reference is
not only particularly relevant for its similar capacity of H H ammonia unit, but also because
this synloop has been designed to be able to operate with a minimum turndown ratio of 30%
in order to cope with the variable availability of hydrogen generated in various PSA units
which are not continuously in operation. This special feature makes this design particularly
suitable to cope with changing in hydrogen availability expected in the H H project.

Ammonia Plant
Construction Experience
KBR built its first syngas & ammonia plant about 75 years ago.
100+ of the 262 plants licensed and designed by KBR were also built by KBR on EPC basis.
The most recent examples of ammonia plants licensed, designed, and built on EPC basis by
KBR are:
 Yara-BASF, Freeport, USA, Ammonia Synloop with a capacity of 2,200 MTD, in operation
since 2018;
 Dyno Nobel, Waggaman, LA, USA, complete Purifier™ Ammonia plant based on natural
gas reforming with a capacity of 2,300 MTD of ammonia, in operation since 2016.
In 2016 KBR completed the landmark Dyno Nobel ammonia plant in Waggaman, Louisiana.
The project utilised integrated KBR solution of KBR's Purifier™ ammonia technology along
with KBR's engineering, construction, and procurement (EPC) services. The facility met and
exceeded all performance parameters for throughput, efficiency, and environmental
performance during handover of operations and management. The time from contract
award to handover was 42 months. Demonstrating KBR's commitment to Zero Harm, the
project reached this milestone with no lost time incident, while executing more than five
million man-hours.
KBR has also partnerships with global EPC contractors that are licensed to build syngas,
hydrogen and/or ammonia plants based on KBR design. When working alongside its EPC
partners, KBR perform the following key activities:
 Provide license to operate and provide performance guarantees.
 Develop basic engineering design (“BED”);

Ammonia Plant
 Review the detail engineering developed by the EPC contractor by providing “post-BED”
services.
 Supply proprietary equipment (“PEQ”), which are the most critical items in the plants
and require special attentions during the fabrication.
 Provide operators training simulator (“OTS”).
 Assist EPC contractor during commissioning, start-up and test-run of the new plant.
 Provide remote monitoring services (“InSite”) during the operation of the plant after the
test-run to ensure that the performance is always optimised.
 Provide services under technical services agreement (“TSA”) to assist the operator to
deal with special maintenance and/or upgrading.
Thanks to the longstanding relationships with certain EPC contractors, those EPC partners
have extensive experience in building KBR technology plants, and we are able to secure
seamless transitions from the design phase to the execution phase.
A listing of all new KBR ammonia plants licensed since 1944 follows in Appendix-B.
