Important parameters unique to the development:
Process is based on simple VSA cycle configuration, The process is designed to operate at low pressure considering availability of biogas at low pressure, The process operates with low cost commercially available adsorbent, The process simultaneously produces high purity methane and carbon dioxide streams, Methane purity of 90% with over 90% recovery is obtained, High purity CO2 is also simultaneously produced (Purity 90 %), The productivity of VSA process (05 mol CH4/kg/hr) is 3-4 times higher than similar process reported for biogas up gradation.
