Russian steelmaker NLMK has announced its commitment to construct a modern modular dust collection system at its Lipetsk production site to treat off-gases from its blast furnace No. 4.
With a capacity of 600,000 cubic meters per hour, the new system will bring residual dust content down by 30 percent, to 5 mg per cubic meter. This will reduce annual dust emissions by 504 mt to reach the level of the best available technologies.
Currently, gases from the BF No.4 are dedusted by a previous generation dust collection system that uses the water sprinkling method.
Investment in the construction of the new dust collection system will total approximately RUB 250 million ($6.89 million), with the launch planned for the end of 2015.
This project is part of NLMK's Environmental Program 2020, aimed at further minimizing the company's environmental footprint. Total investment in NLMK Group's environmental measures will amount to RUB 10.6 billion ($0.29 billion).
