In the Krasnoyarsk Territory, Norilsk Nickel brought the Sulfur program to the finish line.
The Nadezhda Metallurgical Plant (NMZ) launched the third sulfuric acid production line and the fourth neutralization line in comprehensive testing mode. Thus, the entire sulfur dioxide recycling system is fully operational.
The company notes that Norilsk Nickel is now very close to reaching its designed capacity and fulfilling its obligations under the federal Clean Air project.
“Another important milestone has been achieved in the implementation of the Sulfur Program, which allows us to build sustainable operation of the entire complex. The new lines will not only allow us to fulfill the assigned tasks, but also increase the overall reliability of the system,” said Vitaly Muravyov, General Director of NN-Development.
Let us remind you that the Sulfur Program is a project for the utilization of metallurgical gases to reduce sulfur dioxide emissions in the Norilsk industrial region. The total investment in it is estimated at 300 billion rubles. The program will reduce sulfur dioxide emissions at the Novosibirsk Metallurgical Plant by 90% from the 2020 indicators taken as the base.
Norilsk Nickel recalled that gas from flash smelting furnaces is supplied through gas ducts to three sulfuric acid production lines, undergoes wet cleaning, is cooled, and then sent to contact devices, where it is converted from dioxide into trioxide. It then turns into sulfuric acid. Neutralization lines complete the process and convert the acid into gypsum.
Since the beginning of 2026, the installations have already disposed of 160 thousand tons of sulfur dioxide. The peak load of the workshop will occur in the second half of the year, when, according to the plan, the enterprise will reach maximum performance and fulfill annual obligations.
Despite the fact that construction and installation work is almost completed, the Sulfur Program continues to improve: a stage of technical re-equipment is ahead, which will improve certain technological parameters and increase the reliability of equipment.
