국내 초임계 석탄화력발전소에 연소 후 CO2 포집공정 설치 시 성능 및 경제성 평가 = Performance and Economic Analysis of Domestic Supercritical Coal-Fired Power Plant with Post-Combustion CO2 Capture Process

다국어 초록 (Multilingual Abstract)

In this study, Economic analysis of supercritical coal-fired power plant with CO2 capture process was performed. For this purpose, chemical absorption method using amine solvent, which is commercially available and most suitable for existing thermal power plant, was studied. For the evaluation of the economic analysis of coal-fired power plant with post-combustion CO2 capture process in Korea, energy penalty after CO2 capture was calculated using the power equivalent factor suggested by Bolland et al. And the overnight cost of power plant (or cost of plant construction) and the operation cost reported by the IEA (International Energy Agency) were used. Based on chemical absorption method using a amine solvent and 3.31 GJ/tonCO2 as a regeneration energy in the stripper, the net power efficiency was reduced from 41.0% (without CO2 capture) to 31.6% (with CO2 capture) and the levelized cost of electricity was increased from 45.5 USD/MWh (Reference case, without CO2 capture) to 73.9 USD/MWh (With CO2 capture) and the cost of CO2 avoided was estimated as 41.3 USD/tonCO2.
