Iron & steel

Iron is one of the most abundant elements on the earth and the widely used metal across various applications. Globally, majority of the iron produced goes into steel production. By increasing the production capacity, more and more iron and steel global players following trends like energy savings and environmental protection.

Proven dedusting processes and components for process and environmental technology

Iron and steel production is an area of application featuring a huge number of key-processes. To be competitive also in the future, our customers count on minimizing the steel production cost. As a fully integrated part of the production process, our gas cleaning solutions help to reduce cost of production and also to protect the environment at the same time.

Being the original inventor of many gas cleaning processes, GEA can look back onto more than 100 years of plant engineering with satisfied customers all around the world. Also in the future our customers can count on the reliability of GEA gas cleaning solutions.

Dealing with the erection of new production plants, environmental aspects and energy savings are getting more and more important.GEA offers for this purpose sustainable gas cleaning solutions, which help to keep investment and operational cost low.

With a wide portfolio and state of the art technologies, GEA provides solutions for the following sectors of iron and steel production: 

Oxygen Steelmaking Plant

  • Dry primary converter de-dusting
  • Lurgi-Thyssen (LT) Steel Gas process
  • State of the art process without requirement of waste water treatment
  • Highly efficient with outlet dust emissions
