The steel industry is one of the world’s largest manufacturing industries and the highest carbon emitter. At present, the carbon emissions of China’s steel industry have accounted for 15% of the total emissions of the country, and nearly 50% of the steel produced and used in the world every year is produced in China, so the carbon emissions of China’s steel industry also account for about 50% of the total carbon emissions of the global steel industry. In view of this, carbon reduction in the steel industry is crucial for China to achieve carbon neutrality.
Through the implementation of ultra-low emission transformation, can effectively reduce the emissions of air pollutants, including nitrogen oxides, thereby improving environmental quality, low nitrogen transformation is one of the important measures to promote the green transformation of the steel industry, it helps to achieve the organic unity between economic growth and environmental protection. At the same time, it is also in line with the concept of “green development” put forward by our country. The transformation of low nitrogen in the steel industry is of great significance for protecting the environment, promoting green development, enhancing corporate image and promoting cleaner production.
The low nitrogen transformation of the steel industry is mainly through the upgrading of the production links (including raw material field, sintering, pelletizing, coking, iron making, steel making, steel rolling, self-owned power plants, etc., as well as the transportation of bulk materials and products) to achieve the goal of ultra-low emissions. Specific measures include:
1, organized emission control: the implementation of upgrading, reduce the organized emission of air pollutants.
2. Unorganized emission control: reduce unorganized emission by improving production process and management.
3, transport process control: in the transport process also to control the emission of pollutants.
4, clean production control: through regional capacity optimization, energy structure and production process structure adjustment, ultra-low pollution reduction and energy saving and carbon reduction coordinated development, to achieve clean production.
5, Promote advanced technology: promote the application of advanced smelting technology, equipment and management methods, improve energy efficiency and reduce carbon emissions.
6, green design product evaluation system improvement: establish and improve the evaluation system of green design products, promote the development of green manufacturing.
7, accelerate the transformation process: strive to complete the ultra-low emission transformation within the specified time, such as by 2025, more than 80% of the capacity to complete the transformation.
GRVNES focuses on steel, glass, chemical, cement, gas turbine, Marine, internal combustion engine, boiler, distributed energy and other sub-specialized fields, low/medium/high temperature (180℃-550℃) high concentration of nitrogen oxides, high dust and other flue gas conditions customized solutions.
The implementation of the above measures has made breakthrough progress in the transformation of China’s steel industry to low-energy, low-pollution green manufacturing. According to reports, by the end of 2021, 23 iron and steel enterprises in the country have completed the ultra-low emission transformation of the whole process, involving steel production capacity of 145 million tons.
