Chemical absorption processes for low concentration CO2 and comprehensive comparison
捕集低浓度二氧化碳的化学吸收工艺及其综合比较

CO2 capturing has been becoming an important technology to mitigate the global warming,but there is no technology that is ready for large-scale industrial use now.The chemical absorption is the most promising process in all the methods.Research on MEA,PZ-K2CO3,ILs and ammonia are the hot off the press.It is necessary to have a comprehensive comparing on these solvents for knowing their characters and application.It is found that MEA process is much mature,ammonia process has great prospects,IL and PZ-K2CO3 processes need more research,through comparing the properties of solvents and processes,research progress,energy cost,etc.
