Influence of plate geometry and added packing on dispersed phase holdup and slip velocity in reciprocating plate column

A comprehensive study of the influence of plate geometry and the added packing on the holdup and slip velocity in reciprocating plate columns is presented. The use of packing in the interplate spaces of the column is of interest as packing alters the character of dispersion and also provides contact area for the phases. A model is proposed relating slip velocity to the single drop rise velocity taking into consideration the pseudohydrostatic effects and particle-to-particle interaction effects.
