Bialecki ring

Mozenski and Kucharski [2] examined the pressure-drop, overload limit, and flooding limit of a column (0.5 m diameter) packed with Pall rings (35 mm diameter) and Bialecki rings (35 mm and 50 mm diameter) sprayed with propylene carbonate up to 15 bar. Some specific correlations have been proposed and compared with literature data for atmospheric pressure, particularly with the use of the Sherwood diagram for loading-and flooding capacities.

Figure 5.4-23 presents the result of the evaluation of (5.4-27) together with (5.4-28) and (5.4-29) for a random packing of Bialecki rings. This plot is almost identical with the empirical flooding correlation of Mersmann (Fig. 5.4-18). Just the dimensionless liquid load has been replaced by the liquid holdup below loading.
