Research on desorption and regeneration of simulated decarbonization solution in the process of CO2 capture using ammonia method

Study on desorption and regeneration of simulated decarbonization solution using ammonia method for CO2 capture was carried out in order to understand the feature of regeneration of decarbonization solution. The mechanisms about solution desorption after decarbonization were introduced briefly. Under the atmospheric pressure and in the presence of nitrogen carrier gas, several effects related to desorption of simulated decarbonization solution were analyzed, such as temperature, solution concentration, pH, loading capacity, etc. The results showed that the CO2 desorption percentage increased with the increases of temperature, solution concentration and loading capacity, but CO2 desorption percentage increased with the increasing of pH and then decreased.
