Abstract: CO2 capture using ammonia method has become an emerging research hot point due to its characteristics of high removal efficiency,low cost,high absorption capacity etc. The mechanisms about CO2 capture by ammonia method and solution desorption after decarbonization were introduced in the paper. Research progress in this process was reviewed. Several problems affected the application of this technology were analyzed,such as mechanism research,ammonia leakage and energy consumption etc. Industrial test and combined desulfurization and decarbonization should be carried out in near future,so as to push forward the industrial application as soon as possible.
