Principle of biogas purification

Biogas purification: The main components of biogas and natural gas are CH4. The product gas purified by CH4 is biogas (BNG) and compressed natural gas (CNG) when pressurized to 25 MPa.Biogas purification equipment designed and manufactured by Dear air separation can effectively remove impurities such as condensate, hydrogen sulfide and carbon dioxide from biogas and maintain a very high recovery of CH4.
