- Analysis and optimization of the entire production process including the power plant
Why Deutsche Gasrußwerke relies on ÖKOTEC
“We were very impressed by how quickly ÖKOTEC understood our complex processes and developed very good savings measures.”

The Challenge
KG Deutsche Gasrußwerke GmbH & Co (DGW) produces over 30 different carbon blacks for companies in the chemical and tire industries at the port of Dortmund. The medium-sized company supplies electricity and district heating from the resulting process heat to a large number of households in Dortmund, Germany. DGW’s aim is to become the most competitive carbon black plant in Europe. Against this background, there was interest in external expertise for the development of energy efficiency and savings measures as the basis for DGW’s climate strategy.
Benefits
- Expansion of electricity and district heating generation
- Improvement of the site’s carbon footprint and cost situation
The Solution and Implementation
An energy analysis of the entire production process and the power plant, including the steam turbines and condensers, was performed. As the production process is highly integrated, the impact of individual actions on the entire site had to be taken into account in all savings proposals.
- Development of actions to generate additional steam from previously unused waste heat from process systems
- Recommendations for optimizing the process gas/hot air/steam system
- Development of recommendations for measures to produce electricity from previously unused waste heat using steam expanders
DGW is very satisfied with the proposed solutions and plans to implement them successively.
