Coke oven gas is a valuable by-product in the conventional production of coke. It enables the recovery of a wide range of other coal by-products, which, when marketed, make the production of coke even more cost-effective. The main product of a dedicated gas treatment unit, the treated coke oven gas, is used as fuel gas although it can also be used as a feedstock for the production of chemical products.
Some outstanding examples of gas treatment units based on our technology at large-scale coke oven plants are:
- Schwelgern, Germany (155,000 m3/h gas)
- Hyundai, Korea (phase 1/2 170,000 m3/h, phase 3: 120,000 m3/h gas)
- POSCO Gwangyang (160,000 m3/h gas)
- FCFC, Vietnam, to be completed in 2015 (195,000 m3/h gas)
Our processes employ high-performance state-of-the-art equipment and equipment components that ensure efficient, reliable operation of the plants and minimize their environmental impact. Our wide range of technologies and services allows us to provide our customers with tailored solutions, including:
Raw Gas Treatment
- Gas condensation and cooling
- Tar removal
- Detarers
- Electrostatic tar precipitators
- Naphthalene removal

Recovery of Useful Products
- Sulphur recovery
- MonoClaus
- Sulphuric acid production
- Conventional
- Emissions-free sulfuric acid plant
- Ammonium sulfate production
- Ammonia recovery
- Phosam
- Coke oven gas treatment for the production of synthesis gas
Emissions Control Process
- Waste water treatment
- Conventional
- Loop reactor
Treatment and Use of Flue Gases for Heating Purposes
- Steam boiler
- Flue gas desulfurization
The treated coke oven gas can be subjected to an additional final desulfurization step so that it can be used as synthesis gas. Instead of treating the coke oven gas, it is possible to use it purely for heating or energy purposes. Here, too, thyssenkrupp Industrial Solutions offers steam generation plants with a corresponding flue gas treatment unit.
