摘要(Abstract)：

有机胺化学吸收法是目前应用于燃煤电厂最主要的碳捕集技术。有机胺再生过程由热驱动，需消耗大量取自汽轮机组的蒸汽，导致燃煤电厂发电效率下降，发电成本大幅升高，限制了碳捕集技术在单机容量和配置数量2个层面的规模化应用。优化系统能量热集成利用是改善上述问题的重要途径。以碳捕集子系统和电厂系统间的热能集成利用方式为主要目标，从热集成优化理论和工程能量系统优化两方面出发进行讨论与分析。在热集成优化理论方面，分别阐述了?分析法和夹点分析法的原理、使用方法，和在煤电碳捕集系统应用的成果以及局限性，提出了建议研究方向；在工程能量系统优化方面，分析了蒸汽抽汽参数优化、蒸汽过热度利用方式、凝结水余热利用方式、碳捕集与压缩余热利用方式和多种辅机应用方式的有益效果，讨论了相关方案在工程实施中可能面临的可行性和经济性问题。文中对相关内容的讨论可为进一步降低系统能耗提供参考与思路。
