| Abstract: | The effects of parameters,including ammonia concentration,CO2 concentration and reaction temperature on CO2 removal efficiency were systematically studied by ammonia scrubbing at a pilot-scale device for capturing CO2 in the flue gas from coal-fired power plants.The nitrogen element content and qualitative XRD analysis in reaction products were completed according to the national standard of China.The dynamics of ammonia scrubbing CO2 was analyzed.The results show that the CO2 removal efficiency was more than 84%,and the CO2 removal efficiency of 93.2% was achieved while the ammonia concentration of 8%,CO2 concentration of 14.98% and reaction temperature of 32 ℃.This study results provides a basis for industrialization. |
