Project:
Dakhni Expansion
Client:
Oil & Gas Development Company Limited (OGDCL)
City/Country:
Islamabad, Pakistan
Synopsis:
Dakhni Gas Processing Plant was installed in late 1980s. This was OGDCL’s first major processing plant. The plant is designed to process 30 MMSCFD of sour wellhead fluids being produced by Dakhni field. ENAR was involved in all the phases of project execution i.e. design engineering, procurement, project management & construction supervision and start-up assistance.
The plant has not been able to operate at its designed capacity due to high concentration of H2S in the feed gas. The H2S removal, amine units and downstream sulfur plant have become a bottleneck. As the quantity of available gas has also increased OGDCL decided to proceed with expansion of the plant.
ENAR was engaged by OGDCL for providing following services:
