07/21/2011 - NLMK has upgraded its aspiration system in the refractory shop at Lipetsk to improve the efficiency of its gas cleaning equipment to the level of best available technologies.
NLMK has upgraded its aspiration system in the refractory shop at Lipetsk to improve the efficiency of its gas cleaning equipment to the level of best available technologies.
The complex revamp of the gas cleaning system, worth RUR57 million, included the installation of a new type of filter installation and a more efficient end-of-pipe technology. The project has helped to reduce emissions of dust generated by the initial material preparation process by almost 80%. All entrapped dust is recycled, and levels of residual dust in outgoing air will be reduced more than 6-fold.
The aspiration system upgrade is part of the company’s plan to minimize the impact of steel production on the atmosphere and to improve local ecology. As part of its Technical Upgrade Program, Novolipetsk currently is upgrading the central aspiration system of Sintering Machines No. 3 and 4. Through the commissioning of new environmentally friendly equipment in 2011, Novolipetsk aims to achieve a 3.5-fold reduction of dusting from sintering machine No. 3, with similar levels of reduction expected at sintering machine No. 4 in 2012. A mixer department upgrade project and the construction of a secondary emission collection and cleaning system in BOF Shop No.2 are also underway.
Since the launch of Novolipetsk’s Technical Upgrade Program in 2000 investments into the Environmental Program have exceeded RUR17 billion. As a result, atmospheric impact from production has been reduced by 22% over the last 10 years, and Novolipetsk’s Environmental Management System has been certified for compliance with international standard ISO 14001-2004. In 2011 the company successfully passed a recertification audit conducted by TÜV Rheinland Cert GmbH (Germany).
