Refinery hydrogen recovery with sepharex membrane systems
Gas separation by membranes is discussed, and presented to be an economically viable process. Commercial installation of membrane systems has been made for hydrogen recovery in refineries and ammonia plants and for CO/sub 2/ removal from various gas streams. The process described in this paper utilizes a flat-sheet cellulose acetate membrane fabricated into a spiral wound element configuration. An illustration of the membrane, named Separex, is provided. These membranes exhibit long-time stability in refinery H/sub 2/ recovery applications even under harsh operating conditions. The successful operation of this system demonstrates the commercial capability of Separex membranes. A comparison with PSA for hydrogen purification shows that membrane systems offer a substantially lower hydrogen production cost and an increase in hydrogen recovery.
