Gas separations using polymer membranes

Abstract

A discussion covers the structural features important in the use of polymers as rate-controlling membranes for gas separations; materials with desirable combinations of high permeability and high selectivity based on solubility selectivity, e.g., butane removal from natural gas, CO2 separation from H2 or N2, or diffusivity selectivity (CO2 removal from natural gas); cross-linked poly(ethylene oxide) polymers as promising materials to remove polar and acid gases, e.g., CO2, from mixtures with light gases, e.g., H2; customizing polymers to achieve high selectivity based on high diffusivity selectivity; polyimides with ortho-position functional groups, which could be solution-processed to form conventional films and membranes; and important attributes for membranes that would be used in chemically or thermally aggressive environments. This is an abstract of a paper presented at the 2011 AIChE Spring Meeting & 7th Global Congress on Process Safety (Chicago, IL 3/13-17/2011).
