93/5000 Nitrogen oxides may be released during titanium smelting, especially in raw materials containing nitrogen oxides or in high-temperature operations. In the production process of titanium, especially in the use of coal as an energy link, it may involve the application of SCR denitrification equipment to reduce NOx emissions.

As an important industrial metal, titanium is widely used in aerospace, military, medical equipment, automobile, sporting goods, chemical industry, ocean engineering and other fields. However, the relatively high cost of titanium alloys limits their popularity in some cost-sensitive applications. With the advancement of technology and the expansion of production scale, the cost of titanium alloy is gradually reducing, and its application scope is also expanding.

However, some parts of the titanium smelting process may indeed produce nitrogen oxides (NOx). Nitrogen oxides are one of the main sources of atmospheric pollution and are usually formed by the reaction of nitrogen and oxygen during high-temperature combustion. These contaminants need to be treated by selective catalytic reduction SCR denitrification equipment. SCR denitrification technology is an efficient nitrogen oxide emission control technology, which is widely used in industrial flue gas denitrification. Nitrogen oxides may be released during titanium smelting, especially in raw materials containing nitrogen compounds or in high-temperature operations. In the production process of titanium, especially in the use of coal as an energy link, it may involve the application of SCR denitrification equipment to reduce NOx emissions.

Reaction formula of selective catalytic reduction system:
CO(NH₂ )₂+ H₂O → 2NH₃ + CO₂
8NH₃ + 6NO₂→ 7N₂ + 12H₂O
4NH₃ + 4NO + O₂ → 4N₂+6H₂O
2NH₃+ NO + NO₂ → 2N2+3H₂O

In order to effectively treat the nitrogen oxides produced in the titanium smelting process, enterprises need to choose the appropriate treatment technology according to their own production conditions and NOx emission characteristics, and may need to combine a variety of technologies to achieve the best treatment effect. Selective catalytic reduction SCR, is a widely used industrial flue gas denitrification technology, through the role of catalysts to convert NOx into nitrogen and water, SCR denitrification equipment in the titanium production of energy use links and may produce nitrogen oxide waste gas production links need to be used to achieve clean production and meet the requirements of environmental protection.

In order to effectively treat the nitrogen oxides produced in the titanium smelting process, enterprises need to choose the appropriate treatment technology according to their own production conditions and Nox emission characteristics, and may need to combine a variety of technologies to achieve the best treatment effect. With the increasingly stringent environmental regulations, continuous technological innovation and improvement is also an important way to achieve cleaner production.
