Preparation and Simulation of Polycarbonate Hollow-Fiber Membrane for Gas Separation

Abstract

In present studies, the gas separation in hollow-fiber membranes was investigated theoretically and experimentally. Hollow fibers were prepared by melt-extrusion method at speed of 110 m/ min. Simulations were performed for gas absorption in liquid absorbents. Simulations were performed for absorption of CO₂ in aqueous solution if K₂CO₃. Moreover, the simulation results were validated with experimental data obtained from literature for physical absorption of CO₂. The simulation results were in good agreement with experimental data. Simulations showed percentage removal of 75 % for CO₂ removal. The results indicated that hollow-fiber membranes have a good performance in the area of gas absorption.
