Experimental Study on Regularities of Carbonation for CO₂ Capture Using Ammonia Solution

Abstract:

The regularities of carbonation in the process of CO₂ capture were investigated using ammonia solution by laboratory-scale and bench-scale device. The research showed that the lower volatility of NH₃ and higher rate of carbonization in solution could be achieved with ammonia concentration ranging from 10 to 16 wt%. The emission of ammonia accelerated with the increasing of flow of flue gas, and the bubbling function of air was apparent in a lower CO₂ volume fraction, which has an adverse effect on carbonation of solution. Benefits of environment and economic could be achieved in CO₂ capture using ammonia solution so long as appropriate ammonia concentration, the flue gas flow and volume fraction of CO₂ were determined.
