MMC Norilsk Nickel is to reduce SO2 emissions from its metallurgical production facilities in Norilsk, Russia.
As part of its air emissions programme, the firm has posted a tender for set works related to implementing SO2 recovery technologies at copper and Nadezhda metallurgical plants.
The new technologies will recover 95% of SO2 emissions from the plant's waste gases.
The chosen contractor will construct and install deep dust separation systems at a flash furnace at NMP and Vanukov furnace at CP, and construct SO2 concentration units at a flash furnace at NMP and Vanukov furnace at CP.
The contractor will also renovate the sulphur utilisation units at NMP and CP so that all of the concentrated SO2 can be processed.
MMC has scheduled to begin work at both plants in December 2011.
