AbstractSolar-assisted post-combustion carbon capture system is studied to compensate the energy penalty of coal-fired plant due to absorbent regeneration. The system is highly integrated with the amine-based carbon capture process coupled with solar thermal sub-system. The dynamic performance is largely affected by the variations of parameters and the fluctuations in solar collectors. Anexperimental facilityof solar-assisted chemical absorptionpilot with two types of collectors (parabolic trough and linear Fresnel) was constructed in this study. The impacts on the absorbent regeneration performance were studied on the dynamic variation of the solar heat and the operating temperature of the reboiler. The results show that an optimum ration of liquid-to-gas of 2.5-3.0 was determined at the lowest of the required regeneration energy. The study suggests thata better understanding of the key parameters associated with both capture process as well as the solar assisted sub-system if of importance for the overall operation and control.
