T2 Hybrid separation processes: Modeling and design of membrane-assisted distillation (completed)

Sub-Coordinator: Prof. Dr.-Ing. Andrzej Górak

Researchers: M. Sc. Bettina Scharzec, M. Sc. Thomas Waltermann

Cooperation between: TU Dortmund and BASF SE

The project objective is the development of a systematic design method for membrane-assisted distillation processes. Building up on the results of the SFB/TR 63, suitable membrane processes and potential combinations with distillation will be identified and evaluated. The anticipated design method facilitates a targeted integration of the experimental characterization of separation processes with optimization-based evaluation of process variants. Instead of focusing on a specific membrane technology it will cover a wide range of membrane separations. The process design method requires the identification of the necessary modelling depth of each separation unit. An extensive experimental program on multicomponent distillation in packed columns, performed at the industrial partner supports the theoretical studies on modelling accuracy of distillation, using different modelling approaches.
