The use of polymeric membrane technology is an exciting approach toward the removal of acid gases, namely, carbon dioxide and hydrogen sulfide, from natural gas streams. Polymer membranes exhibit good mechanical, thermal and chemical stabilities. These membrane materials can also possess desirable transport properties such as high permeability and selectivity. A number of studies have attempted to improve these properties without compromising the advantages of existing technologies. Various preparations and structures of polymer membranes were reviewed. The structure-property analyses of these polymer membranes used for acid gas removal followed by their selectivity-permeability relationship and economic aspects are considered here.
