NLMK Group, an international metallurgical company, was awarded a gold medal at the 26th International Industrial Exhibition Metal-Expo 2020 for the construction of a complex for the waterless cooling of metallurgical slag on the site of the Novolipetsk Combine. The project, implemented as part of the ongoing environmental modernization, made it possible to reduce the emission of hydrogen sulfide by 3.5 times in the relevant area.
Previously, water was used to cool the blast furnace slag. The reaction of hot slag with water leads to the release of hydrogen sulfide. Despite the fact that the average content of this substance in the city air is several times lower than the maximum permissible concentration, the smell itself caused discomfort for residents of nearby areas. The new complex makes it possible to completely dispense with the use of water and, accordingly, eliminate the smell and significantly reduce the content of hydrogen sulfide in the city air.
The complex was built on the site of a slag accumulation site. During the construction, 6 million tons of slag and other secondary resources accumulated until the 90s of the last century were processed, and about 500 thousand tons of iron was recovered, which was reused for the production of iron and steel. The remaining material was used in the construction of the complex itself and other facilities.
Investments in the project amounted to more than 2 billion rubles.
