Dispersed Phase Hold-Up in Packed Columns Containing Random and Structured Packings

Dispersed Phase Hold-Up in Packed Columns Containing Random and Structured Packings 

The figures show that all packings are characterised by a qualitatively equal course of the function of the dispersed phase hold-up x. Up to a certain distance from the flooding point uc uc,Fl Fig- 7-2, line A-A, the dispersed phase hold-up x is not dependent on the specific flow rate of the continuous phase uc- 

The dispersed phase hold-up x, as a function of the specific flow rate of the dispersed phase ud, is now plotted in a graph, using the flow rate uc of the continuous phase as a parameter. Figs. 7-4 and 7-5. The result is a linear relationship. 

Influence of test system on dispersed phase hold-up X under normal temperature and pressure. 

The linear relationship between the dispersed phase hold-up x, acc. to Eq. (7-2), can be seen in Figs. 7-2, 7-3, 7-4, 7-5 and 7-6. It therefore applies to liquid/liquid systems in the range below the loading line, i.e. for
