With the aggravation of the unprecedented greenhouse effect, the reduction of greenhouse gases which mainly consist of CO 2 has caught high attention by global scholars. The membrane absorption of CO 2 from the flue gas seems a promising alternative to conventional absorption methods like chemical absorption. In this article, the principles of the membrane absorption process were discussed. The research development and current status of CO 2 capture in flue gas using a hollow fiber membrane contactor were reviewed. The affecting factors included the membrane structure and material, module connection form, gas and liquid flow pattern and absorbent. Also, these factors that affected the separation performance of mass transfer processes, as well as the mass transfer coefficients and models for CO 2 absorption were critically discussed in the tube side, shell side and membrane. Also, an experiment system for CO 2 absorption in a membrane contactor was dipicted. The modeling works were validated with experimental results. Additionally, the deficiencies of present development in membrane gas absorption of acid gases and recommendations for future pilot-scale applications were proposed.

Innovative advanced solvent based capture processes (ASBCPs) employing sophisticated separation mechanisms have emerged as essential solutions that may dramatically reduce high energy requirement of CO 2 separation in capture plants. This study systematically characterises useful mechanisms of several such ASBCPs, being mostly at relatively low technology readiness levels. Based on improved understanding of these emerging ASBCPs it is shown how they can contribute to achieving energy efficiency benefits and thus increase CO 2 capture efficiency. It is followed by an analysis of practical examples of all ASBCPs recently presented in academic and patent literature. Finally, major challenges of discussed emerging ASBCPs are identified showing potential directions for further research and development. Overall, innovative ASBCPs employ very different mechanisms translating to different energy efficiency benefits in various CO 2 capture applications. The provided technological account along with the identified challenges may be useful for capture process developers which will be able to bring the most promising ASBCPs to higher technology readiness levels and finally they can be employed in the practice.
