ArcelorMittal Poland Signs Acceptance Certificate forEnergy-Efficient Gas Cleaning PlantPrimetals Technologies has implemented gas cleaning plant to increase dry dust
recycling while reducing energy consumption and improving green credentials
Lowers ongoing maintenance requirements

As part of ArcelorMittal’s initiative “Smarter Steels for People and Planet”, ArcelorMittal is focused onminimizing the environmental impact of their operations. This means investing in innovative iron andsteelmaking processes that are more efficient, use less energy, and emit significantly less CO2. To
support this purpose, ArcelorMittal Poland placed an order in 2021 with Primetals Technologies to supply
a gas cleaning plant for its blast furnace No. 2 in Dąbrowa Górnicza, Silesia Voivodeship, Poland.
Recently, ArcelorMittal granted the final acceptance certificate (FAC) to Primetals Technologies.
The gas cleaning plant is an essential component in any blast furnace complex and is responsible forensuring emissions from the blast furnace are in line with environmental norms.
Advanced Technology
The new gas cleaning plant includes the complete system from the furnace offtakes through to theexisting gas network. Primetals Technologies supplied the key components, including the cyclone, wet
scrubber and demisting vessel. This has allowed ArcelorMittal Dąbrowa Górnicza (AM DG) to increase
the amount of dry dust recovered for recycling and reduced the requirement for waste-water processing.
Additional benefits from the new equipment are an improvement in energy efficiency of the plant anddownstream units and a reduced need for maintenance-related labour. This has made the whole plant
more cost-effective to run and improved the green credentials of the operations.
Project Excellence
Construction of the new gas cleaning plant was undertaken by consortium partner Mostostal Zabrze
Realizacje Przemyslowe (MZRP). With a 90-day shutdown window for demolition and construction, themajor units were built in parallel to blast furnace operation, thereby minimizing the work required during
the shutdown period. These modular units were then lifted into place utilizing a 1000-ton crane.
