Gas processing technology

How can we transfer innovative technologies into the fields of hydrogen production and synthesis (with a focus on PtX: methanol, DME, SAF, …)? This issue is the main focus of the Department of Gas Process Engineering, from laboratory research to real-world application. Our work encompasses feasibility studies, experimental investigations, and process developments, as well as engineering for the implementation of process plants on a container scale.

Furthermore, we conduct detailed R&D within industrial and corresponding publicly funded projects that address specific specialist topics within our expertise. This includes studies on reaction engineering and catalyst screenings, along with associated analytics, technology and process evaluations based on cost estimation methods, and both basic and detailed engineering (including circuit design, automation, and process safety). We have access to appropriate software, laboratories, analytics, and a fully-equipped workshop to fulfill our tasks, allowing us to manufacture smaller plants or prototypes.
