This study analyzed the reduction effect of CCS on air pollutants when CCS is applied in Korea. Also This study was conducted to contribute to the spread of CCS and the necessity of further study on the environmental impact of CCS. In this study, two scenarios for applying CCS in Korea were set up and the reduction effect of air pollutants(SOx and NOx) by CO2 capture was quantitatively analyzed using the environmental performance coefficient of the previous study. Also The reduction effect of PM2.5 of CCS was analyzed by assuming secondary PM2.5 formation of air pollutants.
When a new thermal power plant of 1,000 MW was operated for one year, the reduction amount of SOx was 4,853 tons, which was reduced by 99.5%, and the NOx emission increased by 67 tons. When Oxyfuel Combustion Capture and Pre-Combustion Capture were applied to existing power plants, SOx and NOx were reduced by 82,981 tons and 44,021 tons, respectively.
As global efforts to reduce greenhouse gas emissions are continuing to expand, CCS will soon be introduced in Korea. CCS is a technology that can reduce CO2 and air pollutants together. In the future, PM2.5 related environmental problems that are going on in the future should be sourced from the source of greenhouse gas mass sources and various researches for introduction of domestic CCS will be needed.
