Review of liquid absorbent behaviours in membrane gas absorption process

摘要

Emission of CO2 becomes a major problem to all people everywhere and a famous debate title among scientists and politicians worldwide. Uncontrollable of CO2 emission will be caused the climate change or global warming. Recently, CO2 removal from flue gases of power plant using membrane gas absorption (MGA) technology has attracted many researchers throughout the world. The advantages of MGA are offer higher performance compared the conventional approaches, environmental friendly, easy to handle as well as low cost of maintenances. In this paper, criteria, type, scenario and trends of liquid absorbents for MGA will be reviewed. Strategies on further development of this process are also proposed.
