| Outline of Final Research Achievements |
Carbon dioxide capture and storage technology has attracted recent attention for the mitigation of CO2 emissions; however, to facilitate its commercial implementation, its capture cost should be further decreased. This research proposes an innovative energy-saving process using chemical absorption by a solid in a circulating fluidized bed. In this process, the reaction heat that accompanies absorption is successfully supplied through a heat pump to achieve thermal decomposition in a regenerator, leading to recirculation of all process heat into the process. Absorption and fluidization experiments were conducted to determine the separation performance. An energy balance of the proposed process was simulated using the experimental data with a commercial process simulator as compared with conventional counterparts.
