Abstract
Membranes have gained commercial acceptance as proven methods to recover valuable gases from waste gas streams. This paper explores ways in which gas separation membranes are used in the refinery and petrochemical industries to recover and purify hydrogen. Several case studies using Separex® membranes to recover hydrogen from hydrocracker offgas, ammonia purge gas, and methanol purge gas are discussed.
