Proprietary adsorption technology is being used to purify gas extracted from a Class I sanitary landfill in Los Angeles County, generating about 1 million CF/day of pipeline-quality methane from 25% of the 172-acre landfill. An underground collection system withdraws contaminated methane from the landfill and routes it through 2 pretreater vessels to remove moisture, hydrogen sulfide, and other trace contaminants. The gas then moves to molecular-sieve vessels where carbon dioxide and remaining contaminants are drawn off. Contaminated effluent from the pretreaters is used as fuel to heat the molecular-sieve regeneration system. Southern California Gas Co. will sell the processed gas at prices competitive with other new forms of energy. The Los Angeles County Sanitation Districts will receive a royalty for all gas sold.
