Upgrading Biogas to Biomethane by Physical Absorption Process

摘要: Biogas is generated from anaerobic digestion of organic wastes by micro organisms. It a relatively simple and economical method to produce fuel waste. has composition methane as the main component with 50–70 percent, carbon dioxide around 30–40 percent and, hydrogen sulphide moisture in trace quantities. The biogas varies depending upon substrates used. raw digesters properly scrubbed purified remove unwanted gases like CO2, H2S upto certain required level. In this work, upgrading system 2 m3/h capacity been developed for removal biogas, indispensable get biomethane. Developed system, upgrades up 96- 97% biomethane at 10 bar column-operating pressure 1.5- 2.5 in-flow rate 1.75 water inflow rate.
