Abstract

Abstract: An operational model is developed to evaluate and predict the permeation performance of mixed gas through poly(dimethylsiloxane) (PDMS) membranes by combining the ideal gas permeation model with the experimental analysis of the mixed gas transport character. This model is tested using the binary and ternary mixed gas with various compositions through the PDMS membranes, and the predicted data of the permeation flux and the compositions of the permeated gas are in good agreement with the experimental ones, which indicates that the op-erational model is applicable for the evaluation of the permeation performance of mixed gas through PDMS mem-branes.

Key words: operational model, poly (dimethylsiloxane) membrane, mixed gas, permeation performance
