Abstract

Computer simulation was carried out for the system of ternary gaseous mixtures where the object component had the intermediate permeance among the mixtures. As for the model system of the 3-component mixtures, the gaseous mixtures of N<SUB>2</SUB>/CO<SUB>2</SUB>/H<SUB>2</SUB>O having molar compositions of 0.78/ 0.12/ 0.10, which is a typical composition of flue gases, were separated by a single permeator and two stage modules of various configurations with membrane permeances in the order of H<SUB>2</SUB>O> CO<SUB>2</SUB>> N<SUB>2</SUB>. Two-stage cascade configuration improved CO<SUB>2</SUB> concentration in product stream in comparison with a single permeator, while the power consumption increased. Among three types of configuration of two-stage modules : permeate product of two-stage membrane series (abbreviated as PR-TSS), permeate product of two-stage membrane cascade (PP-TSC) and retentate product of two-stage membrane cascade (RP-TSC), the RP-TSC was found to be the best configuration for concentrating CO<SUB>2</SUB> which has the intermediate permeance among the feed gases.
