The project is one of 180 activities of the integrated environmental program of Norilsk Nickel on the Kola Peninsula, the total amount of financing of which will exceed 71.7 billion rubles by 2031.
The key objective of the new system is to reduce sulfur dioxide (SO2) emissions from fluidized bed furnaces in the refining workshop as part of an integrated gas purification system. The project is expected to reduce SO2 emissions by almost 1,000 tons per year.
The practical implementation of the project started in December 2022. A building was erected for him, where four modern four-floor Russian-made electrostatic precipitators were installed. The share of domestic equipment in the new gas purification system reaches 98%.
The commissioning of this gas purification system is an important project for the environmental strategy of the Kola site, said Stanislav Seleznev, Vice President of Industrial Safety, Labor Protection and Ecology at Norilsk Nickel.
"We have been working on its implementation for several years, and significant investments have been made. This is not just an upgrade, it is a qualitative leap in the treatment of exhaust gases, which will allow us to achieve new minimum values for sulfur dioxide emissions, continuing our policy of reducing environmental impact."In addition to the main environmental effect, the new system will also bring economic results. It will allow additional annual return to production of non-ferrous metals. In addition, the quality of the sulfuric acid produced will be significantly improved.
