Abstract

By considering the Hausen stage efficiency EH in the case of a cocurrent multistage process and a similar stage efficiency ED in the case of a countercurrent multistage process, general relations giving the overall efficiency and the concentration profiles in both phases are derived. These relations are then extended to the limiting case of a continuous contact.

Abstract

A simple statistical model of residence time distribution is applied to the dispersed phase for a liquid-liquid co-current flow in a packing. This model leads to a good representation of the experimental distribution curves and to the determination not only of the total hold-up but also of the stationary hold-up. The parameters of the model, mean free path and mean rest time, have a clear physical signification.
