As the main gas of the greenhouse effect, carbon dioxide (CO2) must be effectively captured and recycled, and the high separation efficiency and low cost of membrane separation make it stand out to remove CO2 among many gas separation methods. Considering the gas contained in the flue, a more efficient CO2 membrane separation method is proposed, that is, improving the separation coefficient by adopting a separation device coupled with multi-layer separation membrane and absorption membrane. If this method is used, the separation quality can be improved, the purity of CO2 will be close to 99%, and the cost for the developed separation technology can be greatly reduced. As a result, this research is devoted to describe a novel method of removing CO2 from the flue gas, which is by combining separation membrane and absorption membrane. The method can reduce the cost and external pollution, combined with various advantages, to improve the separation quality as far as possible.
