Study on Removal of CO_2 by Ammonia Method

The effects of ammonia concentration,carbonized ratio,retention time and temperature on removal of CO2 by ammonia meth-od were investigated with the flux of 500 mL/min at room temperature.The results show that the removal efficiency of CO2 by ammonia absorption and the reaction velocity increase with the increase of ammonia concentration.The carbonized ratio has a significantly nega-tive effect on removal of CO2 by ammonia method,the higher carbonized ratio,the lower removal efficiency.In addition,a higher re-moval efficiency can be observed with the long retention time.
