Aiming to address challenges posed by the complex composition and high emissions of flue gas in the iron and steel industry,this paper analyzes the characteristics,development status,and future trends related to each carbon capture technology.Currently,the absorption method is the most mature and effective carbon capture approach with demonstrated commercial applications in the industry.New carbon capture technologies exhibit great potential for reducing carbon emissions.However,most of these technologies are currently only in the experimental stage,which poses a significant hurdle for future adoption.Composite capture technology,utilizing membrane contactors,overcomes the limitations of individual capture technologies and has already been successfully deployed in the coal-fired industry.In practical applications,the selection of appropriate capture methods should be based on the characteristics and concentration differences of flue gas for each steel production process.Further research is needed on the carbon capture technology in the future steel industry.
