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

GEA Insights
The breakthrough that changed spray drying
In 1976, NIRO engineers responded to a competitive challenge by rethinking what spray drying could do. Their idea became the multi-stage dryer MSD. Fifty years later, the same fundamental principle helps turn liquids into the powders used in essential nutrition products and important medicines around the world. Refined through decades of engineering expertise, customer insight and continuous development, MSD is a story of innovation with lasting impact.
Beyond the machine: unlocking better plant performance
An efficient machine does not automatically make an efficient factory. Real improvement often starts by looking beyond individual equipment and understanding how processes, energy systems and operating decisions affect one another. It’s a holistic approach designed to uncover opportunities that might otherwise be missed.
How a valve reshapes the way food and drinks are made
In food and beverage plants, valves are commonly operated using compressed air. GEA Hydract® Actuation Technology moves valves with water instead, in a closed, digitally controlled circuit. The result is a valve that can be held exactly in place and steered in fine-tuned steps. This results in lower energy use and greater control.
