Review on Capture and Utilization Technology of Carbon Dioxide in Coal-fired Power Plant

As global warming worsens, control technology of carbon dioxide emission is attracting more and more attention. The paper comprehensively introduced domestic and overseas development of technology for carbon dioxide capture,utilization and storage,and focused on the technology of carbon dioxide capture using aqueous ammonia solution, carbon dioxide storage by mineralization,and a novel process integrating carbon dioxide capture with mineralization. The analysis shows that,compared with other traditional amine- based absorbents,aqueous ammonia solution has large carbon dioxide capacity,high reaction rate,good oxidative stability,and low regeneration energy; Carbon dioxide storage with mineralization also has huge potential for large mineral resources reserves,wide mineral distribution,and wide range of adaptability; The integrated process has good development prospects as it overcomes traditional defects such as high energy consumption and low efficiency,and produces high value byproduct that lowers the cost.
