"CCUS" technology, as a key technological pathway for addressing global climate change and achieving large-scale low-carbon utilization of fossil fuels, is particularly crucial for the steel industry to achieve its deep carbon reduction goals. In 2023, Wuhan Iron & Steel Co., Ltd., in collaboration with the Yunnan Provincial Academy of Ecological and Environmental Sciences, Kunming University of Science and Technology, and the Institute of Process Engineering, Chinese Academy of Sciences, jointly applied for the Yunnan Provincial Research Project on "Research and Demonstration of Key Technologies for Low-Cost Carbon Dioxide Capture, Resource Utilization, and Storage in the Steel Industry." The project comprises four sub-projects: "Current Status of CO2 Emissions in Yunnan's Steel Industry and Feasibility and Potential Assessment of Carbon Capture," "Research and Development of Key Materials and Processes for Carbon Dioxide Absorption and Capture in the Steel Industry," "Research and Development of CO2 Storage and Resource Utilization Technologies in the Steel Industry," and "Integration and Demonstration of CO2 Capture Technology and Resource Utilization in the Steel Industry."
This project represents a key action by Wuhan Iron & Steel Co., Ltd. to proactively innovate and practice green and low-carbon development. It will provide practical experience and technical cases for the "dual carbon" work of the steel industry in Yunnan Province and even nationwide, and has significant exploratory and demonstrative significance for promoting the overall emission reduction process in the steel industry. The landmark project is the construction of a pilot demonstration unit by Wuhan Kunming Co., Ltd., capable of capturing 1,000 tons of CO2 annually from the flue gas of the blast furnace hot blast stove. The key technology adopts the "CO2 phase change absorption technology and multi-component composite phase change absorbent" developed by the Institute of Process Engineering, Chinese Academy of Sciences, to efficiently capture CO2 from the flue gas of the blast furnace hot blast stove, significantly improving the capture rate and purity of carbon dioxide, and effectively reducing capture energy consumption. The goal is to achieve a CO2 capture rate of more than 90%, a CO2 purity of more than 95% after capture, a capture energy consumption of less than 2.2 GJ/ton, and stable operation for more than 2,000 hours. The aim is to achieve substantial breakthroughs in production practice and techno-economic efficiency, laying a solid foundation for subsequent industrial applications.
