Abstract

Abstract: The gas-liquid-solid three-phase fluidized bed is widely used in petrochemical, electrochemical and biochemical processes. Compared with the traditional three-phase fluidized bed, the features of gas-liquid-solid circulating fluidized bed include operation simplicity, large inter-phase contact area, uniform gas-liquid mixture, good heat and mass transfer effect and easy temperature control. Therefore, it can be one of the potential reactors for ammonia decarbonization in coal-fired power plants. Based on the tests of three-phase circulating fluidized bed, the ammonia decarbonization technology with three-phase circulating fluidized bed acting as reactor is simulated and analyzed in Aspen Plus environment. The feasibility of the technology is also discussed.

Key words: CO2 separation, three-phase circulating fluidized bed, ammonia absorption
