摘要：

We have conducted a series of basic experiments for CO2 removal from the flue gas of thermal power plants by use of hollow-fiber gas-liquid contactors. It was confirmed that the stability of PTFE membrane having a high degree of hydrophobicity is more than 6,600 hours and that by improving the degree of hydrophobicity on the surface of the membrane, the durability and performance of the membrane can-be improved. Furthermore, we have confirmed that flow characteristics of fluid in hollow-fiber can be estimated based on Hagen-Poiseuille law. The overall volumetric mass transfer coefficient Ka(=Kxa) of the hollow-fiber gas-liquid contactor is more than 5 times larger than that of a conventional packed bed, which suggests that adoption of the present method has the advantage of making the absorber more compact.
