中文摘要:

      制约碳捕集技术发展的瓶颈之一在于能耗过高，而现有碳捕集能效分析的方法论与适用模型并未从能源转换的共性机制层面揭示碳捕集理论能耗的“天花板”。因此，也较难像热力学经典概念热机、热泵及其衍生研究框架一样，从“理想与现实之间的不可逆性”这一思考原点出发，探索节能降耗的新机制与新途径。从碳捕集中能源转换的普遍特性出发，提出了热力学碳泵这一概念，首先对其在既有碳捕集研究体系中的辅助角色进行了论述，其后建立了基于热力学观点的模型并展开案例分析，最后与既有混合气体分离模型进行了异同讨论，阐述了两者的互补性。对热力学在面向新型工业应用情景下的能效分析进行了可供参考的尝试。

英文摘要:

      The main barrier to development of carbon capture is high-level energy consumption, while the existing methodology and related modeling on energy-efficient analysis of carbon capture could not demonstrate the top-ceiling performance of ideal energy-consumption in aspect of generalized mechanism of energy conversion. Thus, it near impossible to clearly explore the innovative mechanism and pathway of energy-saving and efficient, originating from the consideration on “irreversibility between idea and real status”, like the growing development of classical concepts of heat engine and heat pump, relevant research framework in the field of thermodynamic. Based on the generalized characteristics of energy conversion in carbon capture, thermodynamics carbon pump is proposed as a concept. The assistant role of such concept inside the exiting research framework is presented, than thermodynamics modeling is conducted as well as case studies, finally a comparative analysis between proposed model and separation model of mixture gas is discussed for complementarity. Such work could be considered as a helpful reference on how to apply thermodynamic to serve the energy-efficient analysis for the new application scenario of developing industrial section.
