CORRECTIONS FOR ANALYTICAL GAS-PERMEATION MODELS FOR SEPARATION OF BINARY GAS-MIXTURES USING MEMBRANE MODULES

Corrected solutions for analytical models, originally presented by Rau tenbach and Dahm [1], for membrane-based binary gas separation are pre sented. These models are based on constant pressure in the feed and pe rmeate streams and perfect-mixing in the permeate stream. A comparison of these models with more complete numerical solutions suggests that the analytical models provide excellent short-cut, preliminary design information. The analytical solutions may also be used to assist conve rgence of more complete numerical methods.
