Objective
!Overview of hydrotreating technology
!World HDT capacity
!Sampling of technology vendors and costs
Trans-Energy Research

Purposes of Hydrotreating
! Note: some fluidity in use of terms hydrotreating,
hydrorefining, hydroprocessing, hydrodesulfurization
! Heavy naphtha treated prior to cat reforming
! Jet fuel treated to reduce sulfur and convert
aromatics to naphthenes, raising smoke point
! Diesel sulfur reduced, cetane number enhanced,
some aromatics may be saturated
! Heavy fuels may be desulfurized, though
pressures must be kept high to minimize coking
! Gasoils may be treated prior to cat cracking
Trans-Energy Research
Associates, Inc.
Hydrodesulfurization Process
! C6+ streams likely to have sulfur compounds
attached anywhere in the molecule, with heavier
fractions more difficult to desulfurize
! Hydrogen used with catalyst, 500-800 oF (260-
425 oC), H2 combines with S to form H2S, 95%-
99%+ of sulfur is removed
! Some nitrogen compounds converted to ammonia
! Metals deposited onto catalyst (CO-MO for S, NI-
MO or NI-W for N and HDA)
! Some aromatics, olefins, naphthenes are
saturated, creating methane, ethane, propane,
butanes Trans-Energy Research

Regional Variations in HDT
!N. Am. and W. Eur accounted for two-
thirds of HDT capacity until the 1990s,
when share fell to 54%
!Despite growth in HDT capacity in
FSU/EE, Mideast, Asia & Africa, N. Am.
and W. Eur still have more HDT capacity
as % of crude capacity (64% and 58%)
!Lat. Am lags with HDT:CDU of just 23%,
(though Pemex has large HDT cap)

Gasoline-Oriented HDT Techs
!HDT heavy naphtha pre- cat reforming is
very common
!HDT of FCC naphthas becoming more
common and more sophisticated
!95-99%+ of sulfur may be removed
!Saturation of olefins and aromatics possible
but typically avoided because of octane loss
!Costs range $10-70 mn.

Diesel Hydrotreating Technologies
! Tightening sulfur specs have stimulated massive
investment in new HDT techs
! 95-99% of sulfur typically removed
! HDT improves cetane # and saturates some
olefins and aromatics
! HDA techs have evolved to saturate aromatics
and eliminate sulfur
! GTL technologies also evolving to produce zero-
sulfur synthetic diesels
! Costs range $50-200 mn, HDA

!RDS was rare outside of Japan (Belgium,
Kuwait, S. Korea, UK, US also have)
!FCC feed (VGO) pretreatment more
common, resulting in lower-sulfur light and
middle distillate output
!May also be considered mild hydrocracking
depending on level of conversion

Conclusion: Major Growth in HDT
! Significant regional variations in specs and HDT capacities
! Growth in HDT worldwide; development of better
technologies
! Expect continued interest in lower sulfur fuels and
technologies
! Zero-sulfur fuels are possible
! Other Trans-Energy analyses have indicated costs of
approx 1.5-3.5 c/g for reformulating gasoline, 3.7-8.7 c/g
for reformulating diesel
! Asia example of reducing diesel sulfur, 1990-2008: Major
shift in average sulfur needed just to keep pace with
demand.
