摘要:Carbon capture and storage (CCS) has been identified as an essential technology to meet the internationally agreed goal
of limiting the temperature increase to 2°C. Compared to traditional gas-liquid contactors, the membrane contactors
provide many beneficial features, including the high specific area, independent gas and liquid flows, modular units and
easy to include internal heat exchange. The solvent carbon dioxide absorption processes employing membrane
contactors is an important technology. Limited by the low partial pressure of carbon dioxide, physical absorption is not
a feasible technology for post-combustion flue gas treatment. However, chemical absorption technology is high energy
consumption. In this study, an innovative hybrid absorption/stripping membrane contactor (HASMC) for physical
solvent carbon capture is proposed. The simultaneous absorption and stripping can enhance the effectiveness of carbon
capture. The device can raise the feasibility of applying physical solvent technology to the treatment of gases with low
carbon dioxide partial pressure. In this paper, computational fluid dynamics simulation of the concentration profiles
and mass fluxes for parallel-flow and cross-flow modules are presented.
