The main raw materials for steel production include raw ore of iron ore, manganese ore, chrome ore, limestone, refractory clay, dolomite, rhodochrosite and other minerals and their finished ores, artificial lump ore, ferroalloys, washed coal, coke, gas and coal chemical products, refractory products, carbon products, etc. In the process of production, steel enterprises not only need to invest a lot of material and energy resources, but also discharge a large amount of waste: waste water, waste gas and solid waste. These wastes are harmful to the environment and a threat to human health. Therefore, we need to purchase the right denitrification catalyst for the ironmaking plant after treatment. What kind of denitrification catalysts are suitable for ironmaking plants? The selection of catalysts needs to be judged according to different industry situations, working conditions and other characteristics, and finally the denitrification catalysts are made to order.

For example, we should first analyze what is the main content of the pollution emitted from the iron smelting plant, our denitrification catalyst is mainly for denitrification, but we also need to understand the metal elements, sulfur content and the proportion of other substances contained in the emission. We also need to consider the working temperature, fuel type, kiln type, working flue gas volume, denitration operation temperature, denitration inlet NOx concentration (mg/Nm3,baseline oxygen %O2), denitration inlet SO2 concentration (mg/Nm3), denitration inlet dust concentration (mg/Nm3), denitration inlet moisture content (%), denitration outlet NOx concentration (mg/Nm3,baseline oxygen %O2), and Ammonia escape requirements (ppm) and other data are analyzed, and then calculated to find out what kind of denitrification catalyst is suitable for selection, and then customized.

Therefore, the more accurate the calculation parameters are, the more accurate the matching and customized denitrification catalysts will be, and the catalysts can meet the actual needs in our working conditions.

Anhui Yuanchen Environmental Science&Technology Co., Ltd ("Yuanchen Technology") is a high-tech enterprise integrating R&D, production and sales of dust bag and denitrification catalyst. The dust bags (mainly PPS, PTFE, P84 and composite series filter materials) and SCR denitrification catalysts have been widely used in cement, steel, glass kilns, waste incineration power generation, biomass power generation, non-ferrous metal smelting and other industries. In the future, Yuanchen Technology will be guided by "becoming the guardian of global ecological environment", always rooted in environmental protection, and insist on the great cause of guarding the blue sky and white clouds. Leveraging on the national ecological civilization construction pattern, we will continue to deepen technology, optimize management, strengthen brand, refine industry and solidify advantages, and create synergistic value for industry through comprehensive and integrated governance and services.
