The removal of CO2 from biogas using a laboratory PSA unit: design using breakthrough curves

Original language description

The production of biomethane from biogas offers the possibility to obtain chemical resources fuels from combustion engines, gas turbine and fuel cells. However, each biomethane application requires specific treatment. This work is focused on the removal of CO2 from biogas as a fundamental step in biogas treatment. A laboratory scale PSA unit is introduced in this paper. The extruded activated carbon was used to construct the fixed bed adsorption layer. The maximum sorption capacity of CO2 was determined from the adsorption isotherm of pure CO2 carried out in a high pressure thermogravimeter. Breakthrough curves of CO2 and CH4 were determined for different volumetric flows of feed. The results were applied for the optimisation of PSA time in order to maximalize the suppression of CO2 from upgrading CH4. The concentration of CH4 is more than 98 % after the upgrading process. The total efficiency of the process was 77 %.
