Outline
Chemical absorption using amine solution takes the dominant position for post combustion CO2 capture of coal-fired power plants, the regeneration of amine is thermally driven, consuming large amount of steam extracted from turbine units, which results in severe power generation efficiency penalty and higher power generation cost. This limitation restricts its large-scale application in terms of both single-unit capacity and project quantity. Optimizing the heat application method in the system is an important approach to address the aforementioned issues. Focusing on the thermal energy integration utilization between the carbon capture subsystem and the power plant system, discussions and investigations are performed from the perspectives of thermal integration optimization theory and engineering energy system optimization. In terms of thermal integration optimization theory, the principles, usage methods, application results and the limitations of the exergy analysis and the pinch point analysis method in coal-fired carbon capture systems are discussed, and the suggested research interests are proposed. In the aspect of engineering energy system optimization, the beneficial effects of steam extraction parameters optimization, superheated steam utilization methods, condensate waste heat utilization methods, carbon capture and compression waste heat utilization methods, and various auxiliary machine application methods are analyzed, as well as the feasibility and economic problem of the mentioned methods during implementations. The research can provide references and ideas for further reducing system energy consumption of carbon capture of coal-fired power plants.
