CSCR®
CSCR® (Carbon Selective Catalytic Reduction) is a dry flue gas purification system.
Flue gas flows through one or more activated coke beds in a modular Adsorber.
The modules are designed to enable a counterflow-process. This results in higher process efficiency and economic advantages.
The technology was developed and patented by Dr. Grochowski.

Business Model
For international projects WVK partners with experienced companies (Licensee), which are familiar with the local aspects of the projects. Within the framework of this partnership, WKV assumes the following roles:
– Licensor for CSCR® and know-how transfer to the Licensee.
– Concept Engineering, Basic Engineering and part of the Detail Engineering
– Supporting the Licensee through supervision from construction, assembly and commissioning on site.
Through the extensive knowledge transfer WKV enables its licensees to represent the WKV technology/CSCR® in the market. WKV supports licensees in all project phases, starting with the pre-project phase up to after-sales support.
Since 1967, Dr. Horst Grochowski has pioneered the world’s first industrial waste gas purification using activated coke. Initially, he developed the cross-flow Adsorber together with the German Bergbauforschung (Coal Mining Research Institute). In 1986, Dr. Grochowski founded the engineering company WKV and further developed the crossflow Adsorber to the counterflow Adsorber. This patented technology has since been known as WKV-Technology/CSCR® (Carbon Selective Catalytic Reduction) and is used worldwide. By 2021, a total of more than 80 plants had been installed worldwide.
The WKV-Technology / CSCR® (Carbon Selective Catalytic Reduction) is used worldwide in a wide range of industries, including:
| Power plants |
|---|
| Steel industry |
| Cement plants |
| Household waste incineration |
| Industrial waste incineration |
| Sewage sludge incineration |
| Chemical industry |
| LCD Glass melting |
