Abstract
An improved process for removing acid gases from raw biogas streams, such as biogas from landfills or biogas from controlled anaerobic digestion, provides for efficient HS removal combined with carbon dioxide removal. The biogas is treated in a biological hydrogen sulfide removal system integrated with a multi-stage membrane gas separation system. The combined system provides for efficient acid gas removal while simultaneously limiting oxygen carryover into the treated product stream by beneficially utilizing oxygen in the biological desulfurization system.
