The modernization of the dedusting system of the steel shop in Dabrowa Gornicza Unit of ArcelorMittal Poland is getting off the ground. It is one of the projects stemming from the EU’s IED (Industrial Emissions Directive), which in Poland came into force in autumn 2014, obliging steel plants to adjust their installations to the BAT (best available techniques) requirements within 4 years.
One of the project preparation stages included computer simulations and detailed analyses of process gas flow at the steel shop, carried out by a company specializing in this field. Engineers from the steel plant in Dabrowa Gornicza also visited other plants of the ArcelorMittal Group, including Gent and Bremen, where similar solutions had been successfully implemented.
A steel shop is a place where liquid steel is made from hot metal and scrap. The process takes place in basic oxygen furnaces (BOF), also called converters. Currently a single dedusting system is in operation at the steel shop, covering all its installations. The new project assumes two dedusting systems: construction of a new dedusting installation dedicated to BOFs only, as well as modernization of the existing system, which will cover the remaining pieces of equipment. Thanks to this solution the flow of process gases treated by the dedusting equipment will increase threefold. Additionally, ArcelorMittal Poland will seal off all emitters in the converter process and mount roof canopies. Thanks to these actions the fugitive emissions from above the steel shop bay will be eliminated.
The cost of the project will exceed PLN 100 m; its completion is foreseen for the second half of 2018. The offer collection has already been completed. The contractor will be selected before the end of July from among renown companies operating on the local, as well as on international markets.
Geert Verbeeck CEO and deputy chairman of the board of directors of ArcelorMittal Poland said that after the modernization of sinter belt no. 3 this is yet another environmental project which we are starting in our Dabrowa Gornicza Unit. This is the best evidence of the fact that we treat environmental protection with the utmost seriousness. The modernization of the dedusting system of the steel shop will not only allow us to comply with future emission limits resulting from EU legislation, but also meet the expectations of the residents of Dabrowa Gornicza as for reducing our environmental footprint.
