Simulation of gas separation in hollow fiber embranes by orthogonal collocation-application to the recovery of carbon dioxide from flue gases in a polyimide pilot plant unit

摘要

The use of polymer membranes for gas separations has expanded in recent years to many industrial applications. Membrane separation is more advantageous than other competing technologies, such as adsportion, absorption and cryogenics, becasue of its relatively low capital investment, ease of operation, spaece efficiency and moderately low energy consumption.
