Reactors for demanding world-scale chemical processes

Rohrbündelreaktor von DWE für großtechnische chemische Prozesse

Since 1955, DWE has engineered and manufactured reactors for technically demanding, large-scale processes in the chemical industry. More than 800 plants realized worldwide document the company’s experience and expertise in implementing process-critical reactions.

The portfolio ranges from multi-tubular and stirred-tank reactors to fluidized-bed reactors and further customer-specific reactor concepts. The basis of every solution is the combination of process engineering know-how, sound materials expertise, and unique manufacturing experience in the construction of large-scale apparatus and reactors.

Market context

Many chemical processes take place within narrow temperature ranges. Yield, selectivity, product quality, and catalyst service life are largely determined by the precise supply or removal of the heat of reaction. At the same time, requirements for plant size, energy efficiency, safety, and sustainability continue to rise. Selecting the right reactor concept thus becomes a central process-engineering decision.

Position and core competence

DWE combines reactor engineering, process engineering know-how, and manufacturing expertise at a single site. Together with technology and licensing partners, we develop reactor solutions for exothermic and endothermic processes — from pilot scale to full commercial scale. The focus is on optimal reaction control, reliable heat transfer, and economic viability in industrial operation. Our particular strength lies in reactors with indirect heat transfer.

The molten-salt technology in particular has established itself over decades as the reference for temperature-critical processes. In addition, DWE realizes reactors using water, oil, gas, and other heat-transfer media, as well as application-specific special solutions.

Molten-Salt Reactors

Process development
and scale-up

Together with technology and licensing partners, DWE develops IP equipment for chemical processes — from the single-tube pilot reactor to the full-scale solution. The close integration of engineering and manufacturing expertise under one roof reduces interfaces, accelerates innovation, and ensures the highest quality standards.
