MARINE OIL SEPARATOR PPT 1st Review

MARINE OIL SEPARATOR
ABSTRACT
Investigation of a novel parameter that considerably enhances the
performance of disk and Belt oil skimmers is introduced. During the
operating of crude oil, the transportation of crude oil requires the
adoption of safety measures in port terminals. At sea accidents are
further serious cause of oil pouring and cause of pollution. By
careful optimization of the angle between the plane of the disk and
the vertical plane, hence the efficiency of a conventional disk oil
skimmer get doubled and this parameter is same as in belt oil
skimmer. Therefore, this is particularly significant as it requires only
a minimum effort to modify existing disk and belt skimmers.
INTRODUCTION
Oil is one of the precious crude and being used in many routine
application of human life. It is not easy to determine the amount of oil
spilled into sea every year but according to the estimate, it is expected to
be around 4 million tonnes in the whole planet and 600.000 tonnes only
for Mediterranean.
Oil Skimmer
The collection of spilled oil is performed by means of special vessels
called oil skimmer
• Skimmers may be:
• Self-propelled – Moved with thrusters for forward and backward
movement operated by joysticks or levers. During an operation it is
possible to position the skimmer in the place of greatest oil
concentration.
• Dynamic – Generally they are positioned on the bow or on side of a
vessel. To make it possible for recovery of the oil and the movement
of a vessel simultaneously.
• Stationary – They are moved and retained by ropes by placing in the
location with the greatest concentration of oil. For many years the
response industry has been making efforts with the development of
methods and equipment for the recovery of oil.
LITERATURE REVIEW
A great number of publications were found during this literature survey
that was expressly devoted to Kaizen. However, some information was
found on the cost and benefits of kaizen at companies. In doing this
survey, it was proved that this research would be important in
contributing studies on this project.
• AEGEAN SEA (Spain, 1992) On 3 December 1992, while ship is
close to the port of La corona on the Galician coast, north west Spain ,
the Greek OBO carrier AEGEAN SEA, during heavy weather, laden
with 80,000 tonnes of north sea Brent crude oil, ran aground. The
vessel is break into two and caught fire. Ship and spilled cargo burned
for several days.
• TORREY CANYON is ran aground on pollard rock on the seven
stones reef, it is near to the lands end, cornwall on 18 march 1967.
Thousand tonnes of oil is spilling from the stricken vessel's ruptured
tanks and during the next 12 days the entire cargo is close to 119,000
tonnes of Kuwait crude oil was lost.
• ODYSSEY 9(Off Canada, 1988) On November 10th 1988, in the
north Atlantic 700 miles of the coast of Nova Scotia while on voyage
from sullom voe, Shetland islands to come by chance Newfoundland,
the Liberian tanker ODYSSEY, in heavy weather almost fully loaded
with a cargo of 132, 157 tonnes of north sea brent crude oil, broke into
two and sank. As it sank fire started on the stern section and the
surrounding oil caught fire.
LIMITATIONS
• In the occurrence of an accident and whenever sea water is reaches to
its deposit, tanks, double bottoms or boxes containing pollutant
liquids, their content must be transferred to the other intact containers,
when possible.
• The spreading and also fragmentation of a slick limit the amount of oil
available to be recovered within a given timeframe, termed the
encounter rate.
2D LAYOUT
WORKING PRINCIPLE
• Rotating Disc and Tray to attract oil which is dumped into collecting
tank.
• Entire assembly is on floating disk and belt with skimmer partially
dipped in water for more contact.
• Solar panels charge the battery and runs the motor and make itself
sustaining model.
• The rubber scraper is attached with disc and belt and collect oil in
storage container.
ADVANTAGES
• There are many important positive points of this system as explained
below:
• No external power is needed of skimming when used with solar power
• It reduced oil pollution of sea
