Laboratory of Thermal Process Engineering
The Laboratory of Thermal Process Engineering was established in November 2017 as a part of the Institute of Chemical Engineering and deals with questions related to new thermal separation processes. Multiple dividing wall columns, rotating separation devices and additive manufacturing are currently the main topics of our research. Within our research approach theoretical and experimental methods are contributing equally to reach our goal of deepened process understanding. The research interests of our group are triggered by the megatrends energy efficiency, modularization and flexibilization of chemical production processes. In this context we are attempting to close the gap between fundamental and application oriented research, keeping an eye on industrial relevance.
Head of Laboratory: Prof. Dr.-Ing. Thomas Grützner
We are looking for a committed student research assistant for stationary and dynamic simulations of multiple dividing wall columns. You should already have some knowledge of Aspen Plus or Aspen HYSYS and enjoy modeling and simulation.
Duration: 6 months
Effort: 30 hours per month

How to find us
We are located at "Uni West"
Albert-Einstein-Allee 47, 89081 Ulm, Germany, Building 47, Room 47.2.225
Successful application to the Carl Zeiss Foundation
The Carl Zeiss Foundation supports our activities in the field of investigating the interaction of liquids on additively manufactured solid surfaces. The funded project represents basic research and is intended to help us answer the question of whether surfaces can be functionalised in a targeted manner by adjusting specific printing parameters.
"Major Research Instrumentation" application successful
Our application for funding for a multiple dividing wall column was positively reviewed by the German Research Foundation (DFG). The plant planned at Ulm University will be built in a specially equipped technical centre and is the first of its kind in the world. [June 2020]
We had exciting and interesting days at the "Fachausschuss Fluidverfahrenstechnik" in Berchtesgaden. The best came at the end: Lena won the poster prize for her contribution "Mehrkriterielle Optimierung ternärer Destillationen: Gesamter Lösungsraum". Congratulations! (Feb 2020)
BASF supports our research
We are glad to receive financial support from BASF on our work related to additive manufacturing of distillation columns. In a joint project (BASF, Ulm University, TU Munich) we are developing solutions for 3D-printed laboratory applications. (January 2020)
