We manufacture VPSA Based Biogas Purifier which produces high purity ( above 95 %) Methane gas from Raw Biogas. It is a piece of very low-consuming equipment and a user-friendly machine. At the beginning of the purification, the biogas passes through a column containing amines, i.e. ammonia derivatives, which capture and absorb CO2 as solvents. After the purified CH4 is separated, the CO2-saturated solvents are steam flushed at high temperatures to be reused.
