Hebei will implement ultra-low air pollutants for

Hebei will implement the ultra-low emission standard of air pollutants for the iron and Steel coking industry from next year

it was learned from the press conference jointly held by the Hebei Provincial Department of environmental protection and the Hebei Provincial Bureau of quality supervision that the Hebei Provincial ultra-low emission standard of air pollutants for the iron and steel industry and the ultra-low emission standard of air pollutants for the coking chemical industry will be implemented on January 1, 2019. The emission limits of major air pollutants in the above two industries have reached the strictest level of the current standards at home and abroad

it is reported that the "ultra low emission standard of air pollutants for the iron and steel industry" is a revision of the "emission standard of air pollutants for the iron and steel industry" in Hebei Province. According to technological progress, and in combination with the requirements of reducing production capacity and implementing ultra-low emission transformation in iron and steel industries in Hebei Province, a more stringent ultra-low emission limit has been formulated

the ultra low emission standard of air pollutants for the iron and steel industry proposes that the emission limits of particulate matter, sulfur dioxide and nitrogen oxides are 10 mg/m3, 35 mg/m3 and 50 mg/m3 respectively under the condition of 16% of the benchmark oxygen content in the flue gas of the sintering machine head (pellet roasting). The emission limits of particulate matter, sulfur dioxide and nitrogen oxides in other processes are 10 mg/m3 respectively. I hope the above sharing can help you cubic meters, 50 mg/m3 and 150 mg/m3. The above emission limits are far lower than the special emission limits of air pollutants of 40 mg/m3, 180 mg/m3 and 300 mg/m3 in the relevant national standards, reaching the strictest level of the current standards at home and abroad

the ultra low emission standard of atmospheric pollutants for coking chemical industry is the first local standard for the emission of atmospheric pollutants for coking chemical industry in China, which tightens the control of the emission of particulate matter in each coking process, and the ultra-low emission limit of particulate matter is 10 mg/m3. Ultra low emission control is implemented for coke oven flue gas. Under the mechanical property test method of 8% reference oxygen content, the emission limits of particulate matter, sulfur dioxide and nitrogen oxide are 10 mg/m3, 30 mg/m3 and 130 mg/m3 respectively. The above emission limits are also lower than the special emission limits of air pollutants of 15 mg/m3, 30 mg/m3 and 150 mg/m3 in the relevant national standards, reaching the strictest level of the current standards at home and abroad

these two standards stipulate that the existing enterprises shall be implemented from October 1, 2020, and the new enterprises shall be implemented from January 1, 2019

according to the "three year action plan for winning the blue sky defense war in Hebei Province" issued by the provincial government, by 2020, all iron and steel enterprises in the province that meet the transformation conditions will meet ultra-low emission standards. By October 2020, the coking industry in the province will have completed in-depth treatment and reached ultra-low emission standards

"Our province has arranged ultra-low emission transformation projects by adding various additives, modifiers and fillers in three years, and they will be completed within three years. According to statistics, of the 359 iron and steel projects that need to be transformed and treated in three years in the province, in addition to 10 projects that have been shut down, 83 have carried out preliminary work, 171 are under construction, 56 have been completed and commissioned, and 39 have been completed. 92 of the coking industry that need ultra-low emission transformation, especially Angang plate and Fengbao pipe industry, are in the surrounding provinces In addition to 7 projects that have been shut down, there are 1 project that has been carried out preliminary work, 45 projects under construction, 25 projects that have been completed and commissioned, and 14 projects that have been completed. " Li Hongyan, deputy director of the science and Technology Department of the provincial environmental protection department, introduced

it is estimated that by October 2020, after the steel and coking industries all meet the ultra-low emission standards, the reduction rates of particulate matter, sulfur dioxide and nitrogen oxides in the province's steel industry will be 15.9%, 64.8% and 64.9% respectively; The reduction rates of particulate matter, sulfur dioxide and nitrogen oxides in the coking industry in the province were 23%, 56.7% and 59.1% respectively
