CO2 Separation Membrane Module

UBE CO2 separation membrane modules (CO2 separator) have polyimide hollow fiber membranes originated from UBE. The modules that carbon dioxide (CO2) permeates preferentially than methane (CH4) can generate biomethane by separating CO2 efficiently from biogas. Biogas is a mixture gas of CO2/CH4 mixed gas obtained from fermentation or digestion of livestock waste, landfill waste, sewage sludge, and so on. Biomethane has been attracted much attention as renewable natural gas (RNG) and is a high purity CH4 concentrated from biogas. The modules are applied to several hundreds of biomethane plants all over the world from 1980's. The modules also can be applied to He or H2 recovery at low pressure operation up to 2.4 MPaG.
