초록
석탄화력 발전소의 연소 배가스를 시간당 1,000 Nm3을 처리할 수 있는 이산화탄소 분리용 pilot plant를 설치하여 화학흡수제인 mono-ethanolamine(MEA)과 2-amino-2-methyl-1-propanol(AMP)를 이용해서 운전특성을 연소 배가스 유량과, 흡수용액 순환유량을 주 실험변수로 분석하였다. MEA 20 wt%를 기준으로 연소 배가스 유량이 100 m3/hr 감소할수록 이산화탄소 제거율이 평균 6.7% 증가하였으며 흡수용액 순환유량이 1,000 kg/hr 증가에 따라 이산화탄소 제거율은 약 2.8% 상승하였고 110 ℃ 재가열기 온도에서 90% 이상의 이산화탄소 제거효율을 나타냈다. MEA가 AMP보다 높은 제거효율을 보였고 MEA(20 wt%) 실험에서 이산화탄소의 제거율이 75.5%인 ASPEN plus의 모사 결과보다 10% 높은 85.5%로 나타났다.
The pilot scale experiments can handle the flue gas up to 1,000 Nm3/hr for separation of carbon dioxide included in real flue gas at coal-fired power plant. The operational characteristics was analyzed with the main experimental variables such as flue gas flow rate, absorbent circulation rate using chemical absorbents mono-ethanolamine(MEA) and 2-amino-2-methyl-1-propanol(AMP). The more flue gas flow rate decreased in 100 m3/hr in the MEA 20 wt% experiments, the more carbon dioxide removal efficiency was increased 6.7% on average. Carbon dioxide removal efficiency was increased approximately 2.8% according to raise of the 1,000 kg/hr absorbent circulation rate. It also was more than 90% at 110 ℃of re-boiler temperature. Carbon dioxide removal efficiency of the MEA was higher than that of the AMP. In the MEA(20 wt%) experiment, carbon dioxide removal efficiency(85.5%) was 10% higher than result(75.5%) of ASPEN plus simulation.
