HOUSTON, Jan. 5 -- Mexican state oil company Petróleos Mexicanos has awarded a $150 million engineering, procurement, and construction contract to Techint SA, Mexico City, and Costain Group PLC subsidiary Costain Oil, Gas & Process Ltd., Manchester, UK, for a 630 MMscfd nitrogen rejection project at its Ciudad Pemex Gas Plant in Tabasco.

Costain said the facility, which will extract nitrogen used in enhanced oil recovery from produced natural gas, will be the world's largest nitrogen rejection project.

The plant will use Costain's proprietary cryogenic process for nitrogen rejection. Costain will provide process engineering for the overall facility and supply key separation equipment.

Main contractor Techint will provide detail engineering and the remaining equipment including the complete gas turbine or compressors and will also construct the facility.
