Intensified Processes
[1]- © d|b|t|a 2017
Objective of the research activities in this area is to develop, investigate, and improve intensified processes. These processes aim for energy savings, reduced demand in space and costs, and replacement of harmful or toxic compounds by deploying integrated and novel unit operations and materials. This incorporates thermal and physical separation processes with and without reaction, as well as tunable liquid multiphase systems. Key elements of the performed research are the systematic analysis of phenomena and operability on the lab scale and the subsequent transition to the mini-plant or pilot-plant scale, as well as the incorporation of model-based methods for process analysis and control.

High Gravity Mass Transfer
Investigation of mass transfer of absorption and distillation processes in centrifugal fields using Rotating Packed Beds (RPBs). Application of RPBs enables space and CAPEX savings through enhanced micromixing and mass transfer, as well as possibility to use high specific surface area packing materials.

Switchable surfactant containing reaction media are investigated to enable the efficient and highly selective conversion of long-chained oleo-chemicals in a macroscopically homogeneous system. Quantitative catalyst recycling and product separation is then enabled by the distinct phase separation behavior of microemulsion systems.
