Optimization, Carbon Capture and Storage, Coal Fired Power Plant, Heat IntegrationAbstract
This study evaluates the optimization of Carbon Capture and Storage (CCS) implementation in a subcritical Coal Fired Power Plant (CFPP). The objective of this paper is to investigate how heat integration can reduce energy consumption of CCS systems and analyze their impact on the overall energy penalty of CFPP. The research focuses on a CFPP with an installed capacity of 3×330 MW and a design efficiency of 38.4%. The results of the baseline case without heat integration indicate that achieving a 90% CO₂ capture rate using an MDEA+PZ solvent requires a reboiler energy consumption of 3.46 MJ/kgCO₂, which results in an energy penalty of 34% relative to the total energy generated by the CFPP and reduces the overall plant efficiency to 27.4%. Process optimization was identified through the utilization of waste heat. Among all the scenarios evaluated, Case 6, which integrates a rich solvent preheater and an inter-stage heater, achieves the highest energy savings, with up to a 40% reduction in reboiler energy consumption and a 10.7% decrease in the overall energy penalty of the CFPP. These findings highlight that strategic heat integration significantly mitigates the energy impacts of CCS implementation which could reduce energy penalty of CFPP.
