用于集中式低浓度碳排放源的大规模CO2捕集技术是实现"碳中和"的关键技术.溶剂吸收法作为现有技术中成熟度最高的低浓度碳捕集技术,依然存在着捕集成本和能耗偏高的问题.为解决现有碳捕集能耗过高的核心痛点,大量新型低能耗吸收剂被开发.但是新型节能工艺作为捕集能耗另一大影响因素,相关介绍则相对较少.调研现有大规模示范项目报道,聚焦于新型节能工艺在已有碳捕集示范项目中的应用情况和实际效果.将现有节能技术进行分类:吸收过程强化技术、热量回收技术、再生过程强化技术.针对不同节能类型,分析现有节能工艺的优势与劣势.在此基础上,对未来节能工艺的发展进行展望,为今后捕集设备节能工艺的选择提供综合性参考.
Research progress on energy saving technology of carbon capture by solvent method
Large-scale CO2 capture technology for low concentration carbon emission source is a key technology to achieve"carbon neutrality".In low concentration carbon capture technology,solvent absorption method as the highest technology maturity still has problems of high capture cost and energy consumption.In order to solve these problems,a large number of low energy consumption absorbents were developed.However,as another major factor affecting capture energy consumption,the energy-saving technology is relatively rare introduced.The existing large-scale demonstration projects were investigated,focusing on the application of new energy-saving technologies in existing carbon capture demonstration projects and the actual results.The existing energy saving technologies were classified as absorption strengthening technology,heat recovery technology and regeneration strengthening technology.According to different energy-saving types,the advantages and disadvantages of existing energy-saving technology were analyzed.On this basis,the future development of energy-saving technology is prospected,and a comprehensive reference is provided for the selection of energy-saving technology for future capture equipment.
