摘要：

A novel theoretical analysis was performed to strip CO2 from an aqueous diethanolamine (DEA) solution using a membrane contactor, which is composed of porous hollow fibers. Governing equations of the system were derived for a cocurrent flow scheme of the feed absorbent steam and the permeate stream in a membrane contactor. Those were successfully solved with the proper initial conditions using a personal computer. The computer program was coded with a Compaq Visual Fortran 6.6. The concentration of free DEA and the flow rate of the recovered CO2 in the permeate could be obtained in terms of the fiber length with changing several operating parameters: temperature in a feed, fractional reaction yield of DEA, feed flow rate and pressure in a permeate.
