A review showed that on the basis of pilot-plant studies, a Biogas Process plant was capable of gasifying 39 percent of the incoming municipal solid wastes. About 80 percent of the produced methane could be upgraded to SNG for sale. The thermal efficiency of the plant was about 42 percent and about 16 Btu of fuel energy in the form of SNG could be recovered from the inputs for each Btu of external energy supplied. Estimated capital requirements for medium-sized plants were $7500/day/ton of nominal capacity. Energy reclamation by the anaerobic fermentation of petrochemical industry wastewaters could save $250,000/yr in a plant producing 30 tons of biochemical oxygen demand per year. The review also covers the conversion of solar energy to methane by way of algae culture in high rate ponds and the anaerobic digestion of algae; microbiology and mechanism including the anaerobic fermentation of alkanes, especially methane; anaerobic denitrification; process developments; and process applications, e.g., food-processing wastes. 156 references.
