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

Topic for a M.Sc. Thesis

We are looking for a student for a master thesis in the field of process optimization with immediate effect. In a joint project with the Technical University of Hamburg, various optimization strategies for thermal separation processes are to be comparatively investigated.

Contact: M.Sc. Lena Ränger, Prof. Dr.-Ing. Thomas Grützner

Topic for B.Sc. Thesis / HiWi Job

We are looking for a committed student to assist our research in the field of dynamic simulation of multiple dividing wall columns. You should have basic knowledge in process simulator (Aspen Plus / HYSYS) and interest in the field of computational process engineering.
