摘要:

目的 在“双碳”目标下,以CO2为主的温室气体排放控制受到高度关注,2023年,我国CO2排放量为126亿t,居世界首位,其中钢铁行业是主要的CO2排放源之一,约占我国CO2排放量的15%。我国粗钢产量占全球1/2以上,降低钢铁行业碳排放,需要考虑我国国情及能源利用特点。因此,有必要研究适合我国钢铁行业的碳捕集与利用技术。 方法 对钢铁生产过程中CO2的排放特性进行了分析,并综述了现有碳捕集技术的研究进展,重点讨论了吸收法、吸附法和膜分离法在高炉煤气CO2捕集中的应用。此外,探讨了炉顶煤气循环氧气高炉技术的利用,并分析了其与吸收、吸附技术的耦合潜力,以期实现钢铁行业的低碳转型。 结论 利用炉顶煤气循环氧气高炉技术,可以结合吸收或吸附法在降低高炉耗碳量的同时降低高炉碳排放,且钢厂余热的有效利用有助于提高碳捕集的经济可行性。转炉CO2喷吹、钢渣矿化利用和钢化联产CO2制化工产品技术的结合,可实现钢铁行业的碳捕集与利用一体化,不仅能够减少钢铁行业的碳排放,还能通过产能优化提升行业的经济和环境效益。

Abstract:

Objectives The control of greenhouse gas emissions, mainly CO2, under the “carbon peak and carbon neutrality” target has received high attention. In 2023, China’s CO2 emissions ranked first in the world, with 12.6 billion tons. Among them, the steel industry is one of the main sources of CO2 emissions, accounting for about 15% of China’s CO2 emissions. China’s crude steel production accounts for more than half of the world’s total, and reducing carbon emissions in the steel industry requires consideration of China’s national conditions and energy utilization characteristics. Therefore, it is necessary to study the carbon capture and utilization technologies suitable for China’s steel industry. Methods The emission characteristics of CO2 in the steel production process are analyzed and the research progress of existing carbon capture technologies are summarized, with a focus on the application of absorption, adsorption, and membrane separation methods in CO2 capture of blast furnace gas. In addition, the utilization of top gas recycling-oxygen blast furnace technology is explored and its coupling potential with absorption and adsorption technologies is analyzed, in order to achieve low-carbon transformation in the steel industry. Conclusions The use of top gas recycling-oxygen blast furnace technology can be combined with absorption or adsorption methods to reduce carbon consumption and carbon emissions of the blast furnace, and the effective utilization of steel plant waste heat can help improve the economic feasibility of carbon capture. The integration of carbon capture and utilization in the steel industry can be realized by the combination of converter CO2 injection, steel slag mineralization and utilization, and tempering co-production of CO2 to produce chemical products technology. It can not only reduce the carbon emissions in the steel industry, but also improve the industry’s economic and environmental benefits through capacity optimization.
