By the end of 2025, the ultra-low emission transformation of steel enterprises in key regions will be basically completed. The opinions on promoting the implementation of ultra-low emission in the steel industry (hereinafter referred to as the opinions) issued by the Ministry of ecological environment and other five ministries and commissions recently made it clear that by the end of 2020, significant progress will be made in the ultra-low emission transformation of steel enterprises in key regions, striving to complete the transformation of about 60% of production capacity, and orderly promote the ultra-low emission transformation of steel enterprises in other regions; By the end of 2025, the ultra-low emission transformation of iron and steel enterprises in key regions will be basically completed, and the country will strive to complete the transformation of more than 80% of the production capacity

the opinion points out that promoting the implementation of ultra-low emissions in the steel industry is an important measure to promote the high-quality development of the industry, promote industrial transformation and upgrading, and help win the blue sky defense war. In addition to promoting the ultra-low emission transformation of existing steel enterprises, the new (including relocation) steel projects across the country should also reach the ultra-low emission level in principle

ultra low emission of iron and steel enterprises refers to the upgrading and transformation of all production links (including raw material yard, sintering, pelletizing, coking, iron making, steel making, steel rolling, and the project aims to develop a self-contained power plant suitable for dairy packaging, as well as the transportation of bulk materials). The opinions put forward several requirements for the organized and unorganized emission of air pollutants and the transportation process

among them, the hourly average emission concentrations of particulate matter, sulfur dioxide and nitrogen oxides from sintering machine head and pellet roasting flue gas are not higher than 10, 35 and 50 mg/m3 respectively; Other major pollution sources: particulate matter, sulfur dioxide, nitrogen oxide row column copper sleeve: refined by brass, the hourly average radioactive concentration is not higher than 10, 50, and 200 mg/m3 except painting

Xu Xiangchun said in an interview with Shanghai Securities News that according to the current national standards for pollutant emissions, the hourly average emission concentrations of particulate matter, sulfur dioxide and nitrogen oxides from sintering machine head, pellet roasting flue gas are not higher than 50, 200 and 300 mg/m3 respectively. It is preliminarily estimated that the transformation of ultra-low emission and unloading in the whole industry will require an investment of 60.7 billion yuan, and the operating cost will be increased by more than 10 yuan/ton

"at the same time, steel mills that implement ultra-low emission transformation can also enjoy preferential policies, such as reduction of environmental protection tax and partial exemption from shutdown during heavy pollution weather warning, which also improves the corporate image and market competitiveness." Xu Xiangchun said

according to the requirements of the opinions, policy support should be strengthened for iron and steel enterprises that have completed the transformation of ultra-low emissions
