Assessment of the effective reaction surface area in the gas-liquid membrane contacting process

摘要

It is of great importance to understand the mass transfer and kinetic phenomena in the membrane contactor to design an appropriate membrane contactor. To the best of our knowledge effect of the membrane surface structure on the gas absorption performance has been asses experimentally in a few papers [1,2]. In all simulation studies, the whole membrane surface was assumed to be active in the gas-liquid contracting process. In some cases, this assumption is not correct and resulted in a considerable difference between calculated and experimental results.
