Optimization of structured packings using twisted tape inserts

In this work, CFD simulations were applied to numerically investigate performance enhancement potential of corrugated sheet structured packings combined with twisted tape inserts. For different twisted tape configurations, pressure drop and mass transfer coefficients were determined and the optimal configuration was selected to be inserted into structured packings. The new structured packing with integrated twisted tapes was compared with an equivalent conventional packing, and finally first experimental investigations of the optimal configuration were carried out. Based on these investigations, it can be concluded that twisted tape inserts have the potential to increase the overall efficiency of structured packings.
