Process Design and Cost Estimation of Carbon Dioxide Compression and Liquefaction for Transportation

Abstract

Energy and cost analysis of the preprocessing for carbon capture and storage transportation such as super- critical 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 (pro- cess 3-2), cascade refrigeration (process 3-2) have been simulated and evaluated. The specific cost is about 4 to 7 $/ton.
