Focus/Key Topic:


Organic Solvent Nanofiltration (OSN) is a pressure driven membrane process. It enables selective separation of solutes on molecular level. In contrast to common processes (e.g.: Distillation, Crystallization, etc.) OSN can be operated under near ambient conditions (neither requiring high temperatures nor change of state). At the moment there are only few full scale applications. However, the attention of chemical and pharmaceutical industry increases vastly due to high potential savings in energy and resources.

At AVT.CVT we investigate systematically this emerging process in order to gain in-depth understanding of observed phenomena. In addition, we aim to define new reliable standards for process design in chemical and pharmaceutical industry. Finally, we want to establish OSN as a new standard unit operation.

The task for this thesis is to plan and conduct experiments using different membranes and multi-component systems. The results gained using an existing lab set-up should be compared to literature data. Finally we want to deduce correlations between interaction of solvent, solutes and membrane (solubility, diffusivity, swelling, compaction, ageing).
