Progress of absorption CO2 by membrane contactor

As a new type of technology of carbon dioxide separation from flue gas,membrane absorption are paid more and more attentions by scholars of home and abroad. Membrane contactor can provide larger interfacial area to increase the mass transfer coefficient comparing to traditional chemical absorption technique. The system process, membrane materials and absorption solution are studied on the membrane absorption of CO₂. A brief introduction is made about mixed absorption solution and the performance on combining different membrane materials with absorption solution. The prospect forecast of membrane absorption is also discussed.
