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.
