In recent decades, next to conventional technologies, such as physical adsorption, chemical or physical absorption and cryogenic fractioning, membrane processes have become an industrial alternative for gas separation. Over the last decade, there have been growing interests in the advancement and applications of membrane-based gas separation technology to tackle various global issues and challenges. Tremendous progress has been made in the development of gas separation membranes. This paper highlights the most promising areas of research in gas separation, by considering the various applications of membrane gas separation processes includes: the Air Separation packages, hydrogen recovery, acidic gas removal, and olefin/paraffin separation.
