Progress in research and engineering demonstration of CO2 capture technology
CCS/CCUS is an effective way to alleviate the increasing serious environmental problems and CO2 capture is an important part of CCS/CCUS.Through decades of sustained development,the chemical amine carbon capture technologies represented by MEA,and the subsequent developed polyamino amines,steric hindrance amines and ionic liquids technologies are gradually maturing,and many of them have been carried out or are undergoing large scale pilot test or industrial demonstration.The research institutions have achieved the key node validation of Technical Review(TR)and accumulated rich experiences.In this review,the pre-combustion,the Oxy-combustion,the chemical looping combustion and the post-combustion capture technologies were briefly introduced with some specific cases,and the main problems with different technologies were analyzed.High capture energy consumption,high equipment investment and maintenance spends,and large amount of wastes were the main factors influencing the capture cost.Moreover,the captured CO2 was mainly used for enhanced oil recovery or sequestration,and the immature CO2 conversion technologies still cannot produce competitive products in the market.
