MEMBRANE FOR SEPARATING CARBON DIOXIDE FROM ASSOCIATED GAS

摘要

A gas separator membrane for purifying associated gas of the present invention uses a porous supporter in which transmittance of carbon dioxide is at least 1,000 GPU and a gas separator membrane consisting of a composite membrane in which a separation membrane where permselectivity to carbon dioxide and hydrocarbon is more than or equal to 10 is coated on surfaces of the porous supporter, selectively separates and removes carbon dioxide from mixed gas of associated gas including carbon dioxide and hydrocarbon, and can easily use associated gas as energy source.
