OSTI ID:87320
Objective was to develop a membrane process for separating hydrogen sulfide and other impurities (CO{sub 2}, water vapor) from low-quality natural gas. A membrane material was identified with very high H{sub 2}/CH{sub 4} selectivity in the range of 40--60; membrane production was scaled up to commercial size rolls; high-pressure membrane and module development and optimization were completed; and a membrane permeation flux of 4{times}10{sub {minus}6} cm{sup 3}/s{center_dot}cm{sup 2}cmHg, twice as high state-of-the-art cellulose acetate membranes, was achieved.
