Experimental investigation of the froth height in columns with sandwich packings

Sohr, J.; Schubert, M.; Flechsig, S.; Kenig, E. Y.; Hampel, U.


Sandwich packings, consisting of alternatingly stacked conventional structured packings with different geometric surface areas, are promising to increase capacity and efficiency of separation columns. Film and froth flow evolve along a stack, which requires comprehensive fluid dynamic analysis. In particular, the froth height is an essential parameter to determine the spatial extent of the flow regimes. Ultrafast X-ray tomography and a 3D-printed pressure drop profile measurement module were applied to independently estimate this parameter. The results are compared with existing correlations.
