Abstract

This overview article discusses fundamental principles of gas sorption and transport in rubbery and glassy polymers and material selection guidelines for gas separation membranes. Comparisons between the performance of membrane-based gas separation systems and more conventional technologies in key commercial applications are provided. Companion articles in this special edition focus on state-of-the-art reviews and descriptions of theoretical and experimental developments important in the technology of gas separations using polymeric membranes.
