无用废气从“环保负担”变为“效益引擎”

Core Viewpoint - The first demonstration project for CO_2 capture and resource utilization from converter gas in China's steel industry has been launched, marking a significant breakthrough in carbon capture and resource utilization [1] Group 1: Project Overview - The project is a collaboration between Beijing University of Science and Technology and Binxin Steel Group, achieving a full-chain closed loop of CO_2 "capture - conversion - reuse" [1] - The project aligns with the national "dual carbon" strategy, focusing on innovative practices of "turning waste into treasure" and "using carbon to treat carbon" [1] Group 2: Technological Achievements - The project employs unique technological pathways to capture high-concentration CO_2 emissions from converter gas, purifying it for direct reuse in steelmaking processes [1] - It represents a transformation from "useless waste gas" to "resource recycling," from "environmental burden" to "benefit driver," and from "unit technology" to "system integration" [1] Group 3: Environmental and Economic Impact - The project is expected to capture 30,000 tons of CO_2 annually, reducing CO_2 emissions by 60,000 tons per year and saving 10,000 tons of standard coal [1] - It will also reduce dust emissions by over 4,000 tons, promoting the increase of high-end steel products by 18% and decreasing CO_2 emissions per ton of steel by over 20 kilograms [1] - The chairman of Binxin Steel Group stated that the project will convert the annual reduction of over 60,000 tons of CO_2 into downstream products with a "zero carbon label," achieving a win-win for environmental and economic benefits [1]
