Work is under way on Nigeria's first gas processing plant.
Site is in Obiafu and Obrikom oil fields about 90 km north of Port Harcourt on the Niger River Delta.
Nigerian Agip Oil Co. Ltd. will operate the plant in a joint venture with Nigerian National Petroleum Corp. (NNPC), and Phillips Oil Co. (Nigeria) Ltd. (OGJ, July 16, 1990, p. 48).
Completion, commissioning, and start-up of the $300 million project are set for first quarter 1993.
ABB Randall Corp., Houston, in a combine with Entrepose-Montalev of France and Delattre Bezons Ltd. of Nigeria, has received a $40 million contract for the unit. ABB Randall will be responsible for engineering, procurement, and overall management of the project.
The Randall design will use a cryogenic turboexpander process with supplemental propane refrigeration and accommodate a broad range of inlet gases, said ABB Randall.
By recovering 85% of the ethane, 99% of the propane, and 100% of the butane, the unit will produce 25,800 b/d of NGL from associated gas currently reinjected in Obiafu and Obrikom fields. Inlet gas capacity was not disclosed.
Recovery volumes of 480,000 metric tons/year of ethane, propane, and butane and 150,000 tons/year of C5's are expected (OGJ, July 16, 1990, p. 48).
NGL will be used as feedstock for NNPC's $1 billion Eleme Petrochemicals Co. Ltd. complex, under construction near Port Harcourt.
