Membrane separation of CO_2 and H_2S from hiogas for industrial cogeneration purposes

摘要

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_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 substantial savings in plant operation costs.
