Gas Chemistry and Gas Treatment
The challenge facing the gas industry is to reconcile the increasing quality requirements of end customers with changing gas qualities. Our Gas Chemistry & Gas Treatment department accompanies this process analytically from the source to the end customer. As an accredited gas chemistry laboratory, we act as an intermediary between basic research and industry and are the point of contact and support for the transfer of new developments to the gas supply.
Main topics
- Odorization & Special Projects
- Liquid Phase Seperation & Power-to-X
- Gas Chemistry & Underground Storage
- Gas Treatment
- Analytics / Laboratory
