Research topics

Forschung

Our research is focused on non-reactive and reactive separation units and especially their internals. Furthermore, innovative technologies towards process intensification are investigated, e.g. energy-integrated and micro-separation units. A further area is the analysis and optimisation of energy-efficient heat exchangers, evaporators and condensers. In order to gain deep process understanding, fundamental research studies on transport phenomena in different systems (e.g. extraction, distillation, evaporation, condensation) are carried out.
