全球大气中二氧化碳浓度正在迅速增加。二氧化碳排放对全球气候变化有影响。需要采取有效的二氧化碳减排策略，例如碳捕获和封存（CCS）来应对这一趋势。 CCS 主要有三种方法：燃烧后捕集、燃烧前捕集和富氧燃烧工艺。燃烧后捕集具有一些优势，因为现有的燃烧技术仍然可以使用，而无需进行根本性的改变。与其他两种方法相比，这使得燃烧后捕获更容易作为改造选项（对现有发电厂）实施。因此，燃烧后捕集可能是第一个采用的技术。本文旨在对迄今为止在化学吸收燃烧后捕集方面开展的研究工作进行最先进的评估。首先将介绍该技术，然后介绍使用该技术所需的电厂烟气制备。将回顾世界范围内的重要研究计划和基于中试工厂的实验研究。接下来是基于建模和仿真的各种研究的概述。然后重点转向回顾不同溶剂的开发和工艺强化。在此基础上，我们尝试从新溶剂、试点工厂、工艺热集成（以提高效率）、建模和模拟、工艺强化和政府政策影响等不同方面来预测挑战和潜在的新发展。 (C) 2010 年化学工程师学会。由 Elsevier B.V. 出版。保留所有权利。
Global concentration of CO2 in the atmosphere is increasing rapidly. CO2 emissions have an impact on global climate change. Effective CO2 emission abatement strategies such as Carbon Capture and Storage (CCS) are required to combat this trend. There are three major approaches for CCS: post-combustion capture, pre-combustion capture and oxyfuel process. Post-combustion capture offers some advantages as existing combustion technologies can still be used without radical changes on them. This makes post-combustion capture easier to implement as a retrofit option (to existing power plants) compared to the other two approaches. Therefore, post-combustion capture is probably the first technology that will be deployed. This paper aims to provide a state-of-the-art assessment of the research work carried out so far in post-combustion capture with chemical absorption. The technology will be introduced first, followed by required preparation of flue gas from power plants to use this technology. The important research programmes worldwide and the experimental studies based on pilot plants will be reviewed. This is followed by an overview of various studies based on modelling and simulation. Then the focus is turned to review development of different solvents and process intensification. Based on these, we try to predict challenges and potential new developments from different aspects such as new solvents, pilot plants, process heat integration (to improve efficiency), modelling and simulation, process intensification and government policy impact.
