World's largest SNG plant operating at Green Springs
Columbia LNG Corp.'s SNG complex, the world's largest, recently began operation at Green Springs, Ohio. The facility has not yet operated at its full design capacity of 250 million CF/day because of insufficient feedstock supplies. The feedstock--light hydrocarbons ranging from methane through hydrocarbons with a final boiling point of 365/sup 0/F--is obtained from Canadian and U.S. sources and is delivered to the plant by pipelines. The plant is composed of 2 separate gas-making trains, each producing 125 million CF/day of SNG and completely self-contained but using common offsites. SNG is produced through feedstock vaporization and pretreatment, steam/hydrocarbon reforming by the British Gas Corp.'s CRG process, heat recovery and methanation by the British Gas Corp. process, CO/sub 2/ removal by the Benfield process, gas drying over a glycol solution, recycle reforming, recycle stream shift conversion, and CO/sub 2/ removal and heat recovery.
