Production of Biomethane from Agricultural Waste Using a Cryogenic Carbon Capture ProcessThis paper evaluates a novel cryogenic carbon capture process to upgrade biogas produced from agricultural waste. The A3C cryogenic process offers simplicity and compactness with lower capital and operating costs compared to many alternative processes. The work addresses potential technical issues presented by trace contaminants in the raw biogas including hydrogen sulphide, organics and siloxanes. It is found that the A3C process offers high CO2 removal with minimal biomethane losses while requiring simple raw gas treatment.
