The melting process generates up to 20 kilograms of dust per ton of steel. This goes into the exhaust air where it represents a big problem. You need to clean the exhaust air to ensure sustainable steel production and comply with clean air regulations. Whatever your furnace type - whether electric-arc (EAF), basic oxygen (BOF converter), argon oxygen decarburization (AOD converter), or submerged-arc (SAF) - we offer you the right technology. 

Our range includes:

  • Complete gas cleaning plants for all metallurgical equipment
  • Primary gas cooling / dedusting
  • Secondary dedusting
  • Gas recovery (BOF, SAF)
  • Dedioxization (by lignite coke)
  • Desulphurization
  • EFATM process

Key features

Blast furnace top gas cleaning

A high-efficiency top gas cleaning system is vital for reliable operation and prolonged campaign life of gas and blast systems, energy recovery, and steam generation facilities. It allows the plant operators to meet the relevant pollution control standards. Thanks to extensive expertise built up over decades, Paul Wurth is an environmental solution provider able to supply technology, systems, and equipment designed to the highest levels of cleaning efficiency, safety, and reliability. With more than 140 references in blast furnace top gas cleaning worldwide, Paul Wurth offers proven design, plant, and core components, as well as plant improvement.

Gas cleaning plants for BOF converters

The challenge of gas cleaning is to provide maximum protection to humans, machinery, and to environment and to effieciently recover valuable constituents of the process gases. Our BOF (basic oxygen furnace) environmental systems ensure high efficiency in recovering these converter gases and offer considerable economic advantages.

Gas cleaning for electric arc furnaces

Our competence in the dedusting and gas cleaning of electric arc meltshops applies to the supply of equipment for new facilites and the modernization of existing facilities. The perfect interaction of all components reduces investment costs and improves efficiency.

Gas treatment for non-ferrous metals plants

Off-gas composition in production plants for non-ferrous metals differs largely depending on the process and the charge mix in the furnace. Based on years of experience developing furnace processes and the downstream fume treatment process, SMS group’s expertise covers a wide range of existing plants and the necessary data from tests to accurately determine the gas compositions for all charge mixes. The fact that the furnace and the fume treatment plant were both developed by SMS group gives us in-depth knowledge and control over the entire process. Furthermore, we consider local conditions in determining the best solution for each application. For example, if water is scarce, a dry solution may be selected instead of a wet fume treatment alternative. Another example of local conditions to
