基于汽轮机安全性的循环流化床机组耦合新型MEA碳捕集系统调峰性能评估
Evaluation of peak-shaving capability based on steam turbine safety for circulating fluidized bed unit coupled with novel MEA carbon capture system
摘要
Abstract
The thermal coupling point of a circulating fluidized bed(CFB)unit and an ethanolamine(MEA)carbon capture system is on the turbine side of the original unit,and the turbine safety directly affects the peak-ing performance of the coupled carbon capture system.A traditional MEA carbon capture system is con-structed based on Aspen Plus,and the optimization measures to improve the CO2 absorption rate are studied.By optimizing and analyzing the effects of lean loading,inter-cooling,and rich solution splitting on regenera-tion energy consumption,a novel MEA carbon capture system with comprehensive improvement on absor-bent,absorption side and regeneration side is designed.The results show that the energy consumption of the novel MEA system is 36.3%lower than that of the traditional system.The impact of coupling the CFB unit with a novel carbon capture MEA system on the minimum output of the steam turbine is analyzed.The peak-ing performance of the circulating fluidized bed coupled with the rich-lean liquid energy storage MEA system is studied.The results indicate that this system can effectively facilitate peak shaving,achieving a peak-shaving coefficient of 1.45 under stable operating conditions.关键词
