Abstract

See full text

A system and method for generating renewable natural gas from raw biogas streams, such as biogas from landfills or biogas from controlled anaerobic digestion of biomass, provides for the efficient removal of acid gases and other impurities, including oxygen and nitrogen from biogas. The biogas is treated in a multi-stage membrane gas separation system integrated with a pressure swing adsorption system to generate pipeline-specification renewable natural gas. The combined system provides for efficient acid gas removal while simultaneously limiting oxygen carryover into the product stream.
