Analysis of CO2-loaded ammonia absorbent and its precipitates by FT-IR and NMR measurement |
| 초록 |
Ammonia water was investigated as a new absorbent of chemical absorption process for removal of CO2 in flue gas. Suitable concentration range of ammonia water was decided in the point of view of CO2 absorption capacity and NH3 loss due to the formation of NH4HCO3 precipitation. Absorption capacity and formation of NH4HCO3 precipitation in liquid phase were calculated by Pitzer model for electrolyte solution. CO2 absorption capacity of 5 mol/kg ammonia water was higher than conventional amine absorbent. The limit of CO2 loading due to precipitation formation was decided at various absorbent concentrations. Absorber could be operated without precipitation by using less than 9 mol/kg of ammonia water at the typical operating condition of an absorber. The optimum operating conditions of ammonia water absorbent for removal of CO2 in flue gas were 40oC, 9 mol/kg, and CO2 absorption capacity was 0.166 kg CO2/kg solution. |
