Project Outline
Natural gas from South Pars Gas Field largely is slated to be shipped
north for home and industrial consumption via a planned 56-inch, 512
kilometer, IGAT-3 pipeline. The gas, mainly from phases 6,7 & 8 of South
Pars Gas Field, will also be reinjected to boost output at the huge
Aghajari field, where output peaked at 1 million bbl/d in 1974, but has
since fallen to 200,000 bbl/d.
The gas intended for injection into Aghajari's 22 oil wells will be
transported via a 56-inch, 512-kilometer pipeline. The pressure of the
gas entering Aghajari gas injection station will be increased 240 bars
by seven turbocompressor units in two stages and transported out of the
station by means of a 24-inch pipeline and injected into the oil wells.

Air Cooler
Each set of turbocompressors is equipped with two air coolers known as
stage 1 and stage 2 air coolers. The first and second stage air coolers,
which operate with 37 KW, 400 volt motors; respectively cool the
compressed fluid by increasing its pressure initially 140 bars and then
258bars to achieve the desired temperature. Each cooler has four
impellers and four motors. Pressure Vessel There are 22 pressure vessels
at the gas injection station, including:
|
|
KO drum of stage 1: 7 units |
|
|
KO drum of stage 2: 7 units |
|
|
Fuel KO drum: 1 unit |
|
|
Fuel LP KO drum: 1 unit |
