Membrane separation processes are being used on an increasingly larger scale for a wide variety of gas mixtures. The objective of this study was to assess the feasibility and economics of a new membrane separation process for upgrading the CH{sub 4} content of biogas produced by anaerobic processes in industrial wastewater treatment plants. The upgraded biogas can be utilized for the cogeneration of electricity and heat, which could result in substantial savings in plant operation costs. This paper reports preliminary results of laboratory and pilot plant studies on the separation of CO{sub 2} and H{sub 2}S from mixtures with CH{sub 4} by means of polymer membranes in the form of hollow fibers. Both synthetic CH{sub 4}/CO{sub 2} and CH{sub 4}/CO{sub 2}H{sub 2}S mixtures and biogas produced in a municipal wastewater treatment plant were used in a range of elevated pressures selected to determine optimum operating conditions. These data were used to develop economic assessments of cogeneration systems fueled with biogas upgraded by membrane systems.
