The iron and steel industry is an energy-intensive sector, and large amounts of waste/ by-products are generated during the steelmaking process, such as CO2, metallurgical slag, and wastewater. Enhancing the development and deployment of treating waste from the steelmaking process will be environment friendly and resource-saving. Capturing CO2 by steel slag (SS) via mineralization is regarded to be an excellent choice due to the high basicity of the slag. In this paper, recent research on the steel slag-based carbon capture and storage (SS-CCS) by mineralization was summarized. Three routes of SS-CCS are compared including, direct gas-solid carbonation, direct aqueous carbonation, and indirect carbonation, respectively. Furthermore, the challenges and prospects for further development of the SS-CCS were discussed.

炼钢过程中废物的共处理:基于矿渣的碳渣捕集和封存

钢铁行业是能源密集型行业,在炼钢过程中会产生大量废物/副产品,例如CO 2,冶金炉渣和废水。加强对炼钢过程中废物处理的开发和部署将有利于环境和节约资源。捕获CO 2由于矿渣的高碱度,通过矿化处理的钢渣(SS)被认为是绝佳的选择。本文综述了矿化对钢渣基碳捕集与封存(SS-CCS)的最新研究。比较了SS-CCS的三种途径,分别是直接气固碳化,直接含水碳化和间接碳化。此外,还讨论了SS-CCS进一步发展所面临的挑战和前景。
