Reactors that work especially for you

We customize your DWE® reactor until it perfectly fits your requirements

If you are producing acrolein (AC), acrylic acid (AA), maleic anhydride (MA), phthalic anhydride (PA) and methyl methacrylate (MMA), our salt-operated reactors are perfect for you. Owing to their excellent process control, they also lend themselves to many more applications.

Our water-, gas- and oil-operated tubular reactors on the other hand are used for the production of ethylene oxide (EO), methanol (MeOH) and others, as well as for XTL (X-to- liquid, GTL) processes, coupled with the need to cut CO2 emissions. This kind of reactor is also used in the power-to-X (P2X / PTX) business area for the production of hydrogene, methane and SNG (synthetic natural gas).

We offer process development and testing in our pilot plants or in a pilot reactor built for you.

Should you have very particular safety, transport or other requirements, our special, custom-made reactors will be of interest.

All our top-quality reactors can be made from special high-grade materials if the process demands it. They have little downtime, have guaranteed spare parts for their long lifetime and reduce your CAPEX and OPEX. We also conduct feasibility and safety studies, carry out revamps or supply start-up services for our reactors systems among other things.
