Abstract
- By using the salting-out phenomenon to induce phase separation, the novel CO 2 phase change absorbents (CPCAs) composed of MEA/water-miscible alcohol/H 2 O were developed. The absorbents using 1-propanol, 2-propanol and tertiary butanol as the diluent were selected as CPCAs. The CPCAs composed of MEA/1-propanol/H 2 O were further examined include the species distributions in the two phases, physical properties, cyclic capacity and absorbent regenerability. In comparison to 30 wt% MEA/H 2 O, the optimal CO 2 cycle capacity of CPCA is 2.59 mol CO 2 /kg which increase 62% and the volume of CPCA sent to the stripper decreased over 67%. The developed CPCAs would benefit to reduce energy consumption of CO 2 capture.
