Nov. 11, 2022 - NLMK Lipetsk has revamped its Blast Furnace No. 3 dedusting system, ensuring a dust capture rate of 99.9%. As a result of NLMK’s continuous environmental upgrades, all of its blast furnaces are now equipped with advanced dedusting systems that are on par with best global technologies.

The new dedusting system comprises: a filtering unit, exhaust fans, a gas duct network, and specialized capture hoods installed over sources of smelting waste. The system uses high-performance bag filters that ensure a reduction of residual dust in off-gases by 95% vs. the pre-revamp level.

The entirety of captured dust is reused in blast furnaces as iron ore feed. Project investment totalled RUB 320 million.

"This project is yet another step in implementing the Environmental Cooperation Agreement through to 2024 between NLMK Group, the Russian Ministry of Natural Resources and the Environment, the Federal Supervisory Natural Resource Management Service (Rosprirodnadzor), and the Administration of the Lipetsk Region. Seven of the nine projects envisaged by the Agreement have already been completed and one more is due this year." said Nikita Vorobyev, NLMK Group Director, Environment and Climate.
