...the process is "Just like
cola fizzing. When the top is popped, pressure is lowered
and gas is released.
Natural gas separated from the
oil is collected and, at most oil fields, enters a pipeline
to be used at power plants, to produce liquefied petroleum
gas (LPG), or be re-injected underground to maintain reservoir
pressures.
Although LPG is the product used
for cooking in Iraq, circumstances in Iraq are not normal
and natural gas pipelines and the countrys LPG plants
are still being restored. Therefore, the valuable natural
gas resource is flared (burned) at the GOSP. As facilities
are repaired, it should be processed into LPG, used for petrochemicals,
or re-injected underground.
Washing the oil removes salts
in the final step in GOSP process. Salts are soluble minerals
dominantly sodium chloride (table salt), but also including
a mix of potassium and calcium chlorides, sulfates and borates.
The natural salt in the Rumaylah oil is removed by mixing
the oil with water from the Qarmat Ali Water Plant to form
an emulsion. As the oil and water mix, the salt
molecules in the oil attach to the water molecules. When the
process is complete, the oil and water separate naturally
and the water containing extracted salts is discarded.
After removing salt the crude oil
is transported by pipeline to the Basra Refinery to be refined
into petroleum products, to powerplants to be used for electricity
production, or delivered for export. About 80% of the oil
produced in the Rumaylah field is exported through an oil
terminal located in the Persian Gulf, according to the Corps
report.
In interviews with engineers and
managers on the gas side of the industry, South Gas Co. officials
are complaining that not enough attention is being paid to
restoring their facilities. South Gas Co. has current liquid
petroleum gas output of 1,200 tons per day, short of the pre-war
3,200 tons per day, says Abdul Ruof Ibrahim, SGC senior engineer.
Nothing has really been done to get back to these levels,
Ibrahim says.
Wright agrees the South Gas plant
has remarkable capacityenough to meet Iraqs
domestic needs in LPG. But of the five trainstwo natural
gas liquids and three LPG, only one of each type is operating.
He says $8 million has been spent on repairs to the LPG line,
but predicts it will become a high priority project soon.
Thair Ibrahim Jabar, South Refineries
director general, has similar complaints about progress restoring
refineries. He says Basra and Meesan are operating at about
62% capacity, producing 136,000 bbl per day. A third refinery
in the south, the 30,000-bbl-per-day Nasiriyah plant, is off
line awaiting repairs. Jabar says that of a dozen refinery
projects initially identified for reconstruction, only one,
Meesan, has been completed.
