Being a kind of important energy and chemical raw material, natural gas can replace fossil fuel for instance coal to cut down the net CO2 discharge. For natural gas purification, separation using membrane technology are considered to be an attractive alternative method. It is necessary to remove acid gases and other impurities for instance, carbon dioxide, hydrogen sulfide. In order to satisfy the transportation regulations and terms of usage, noble gases such as N2 should be added. From the point of view of financial benefits, for industrial production and applications asymmetric membranes are considered to be a considerable solution. This article overviews the latest developments in various natural gas asymmetric membrane purification technologies, the removal of CO2 from CH4 are mainly focused, the separation of N2 and H2S from CH4 are also mentioned. By comparing different material types, polymer membranes, inorganic membranes, mixed-matrix membranes (MMM) and carbon molecular sieve membranes (CMS) are introduced. The related preparation methods and transmission characteristics of various asymmetric membranes are discussed. In practical applications, the asymmetric structure of the hollow fiber of polymer, mixed-matrix membranes (MMM) and carbon molecular sieve membrane (CMS) is mainly studied.
