Thermal Process Engineering and Simulation covers a broad range of processes and technologies in the area of chemical, biochemical, and environmental engineering. The key issues are thermal separation processes, such as rectification, absorption, and - in particular - membrane processes. The applications include the separation/purification of gaseous and liquid products from fermentations (biogas, biohydrogen, bioethanol, ABE), (waste) water treatment, biorefinery as well as industrial production processes. Our work is supported by process simulation, computational fluid dynamics, and multivariate data analysis. The goal is to optimise existing processes and to develop new and better processes.
