Abstract

The effect of dispersed phase holdup and dispersion height on the separation of batch liquid- liquid dispersions is experimentally investigated in terms of the variation in the heights of the sedimenting and coalescing interfaces with time. A model is presented which predicts these separation profiles, knowing the initial drop diameter and the interfacial coalescence time for a dispersion of given height, dispersed phase holdup, and physical properties. This is verified using the present and published experimental data.
