CAN GAS SYSTEMS COMPANY LIMITED has developed a comprehensive methane upgrading solutions tailored to the compositional characteristics of biogas. These primarily utilize the following two advanced processes:
Pressure Swing Adsorption (PSA / VPSA) Technology: Selectively adsorbs and removes impurities such as CO2, N2, and O2 to produce high-purity methane. Membrane Separation Technology: Utilizes the selective permeability of specialized membranes to achieve efficient separation of CO2, N2, and O2, yielding high-purity methane.
Depending on the specific application requirements, either PSA / VPSA, membrane separation, or an integrated combination of both can be flexibly employed to enable efficient biogas conversion and maximize resource utilization.
