Chapter 9 covers gas separation. After a historical perspective, the author recaps the theory of gas separation in dense and finely microporous membranes, as treated in Chapters 2 and 3. A consideration of structural requirements leads to a summary of actual and potential uses, the issues involved in developing suitable membranes, and the opportunities for the newer types of microporous membranes. There follows an analysis of the interaction between selectivity, pressure ratio, and stage cut in determining system performance and the importance of these factors to efficient process design. The remainder of the chapter is devoted to the many applications of membrane gas separation, with examples from the major existing markets: hydrogen recovery from ammonia plants and refineries; production of nitrogen from air; natural gas treatments; and organic vapor/gas separations, as well as from the to-be-developed areas, most importantly carbon capture, hydrogen/CO 2 separation, and olefin/paraffin separations.
