초록

이산화탄소 포집 및 저장 기술 중에서 수송 단계를 위한 전처리 과정인 초임계 압축 및 액화 공정에 대해서 압축 방법에 따른 에너지와 그 때의 비용의 평가가 이루어졌다. 이산화탄소를 초임계상까지 직접 압축하는 경우(공정 1-1), 액화 후 펌프로 초임계상을 만드는 경우(공정 1-2), 이산화탄소의 가압 팽창으로 액화하는 경우(공정 2), 다른 냉매를 사용하면서 그 냉매를 가압, 팽창으로 얻는 경우(공정 3-1), 냉매를 흡수 냉각법으로 얻는 경우(공정 3-2), 캐스케이드 방법을 사용한 경우(공정 4)에 대해서 각각 공정 모사되었으며 그 때의 비용이 평가되었다. 비용은 $4~7/ton으로 추정된다.

Energy and cost analysis of the preprocessing for carbon capture and storage transportation such as supercritical compression and liquefaction is done using chemical simulation model. Direct compression to supercritical phase (process 1-1), liquefaction and pumping (process 1-2), carbon dioxide compression and expansion as a refrigerant itself (process 2), usage of other refrigerant with compression and expansion (process 3-1), with absorption chiller (process 3-2), cascade refrigeration (process 3-2) have been simulated and evaluated. The specific cost is about 4 to 7 $/ton.
