Urban trash methanation background for a proof-of-concept experiment
Abstract
Urban trash methanation (UTM) involves the economic production of pipeline quality fuel gas by the anaerobic digestion of the large organic fraction of municipal solid waste. The UTM process involves four major areas: (1) feed preparation, which includes size reduction and separation of the digestible from the undigestible fraction; (2) digestion (which includes the mixing of the feed, the biological processes of destruction of volatile solids and production of gas, and the reactor variables which affect these processes); (3) dewatering and ultimate disposal of the undigested residue; and, (4) gas preparation, which includes the separation of carbon dioxide from the methane, and the elimination of moisture from the gas.
