Abstract

The dense skin thickness in a dense asymmetric polymeric membrane of the Loeb-Sourirajan type has been optimized for achieving the maximum extent of separation of a binary mixture of permanent gases with the help of Sirkar’s expression for the extent of separation in a single entry barrier separation stage. The expression for fluxes and separation factor through the dense asymmetric membrane were obtained from a recent analysis by Sirkar. The dense skin thickness on the microporous support in a composite membrane has also been optimized.
