Generalization of AIChE and colburn models for tray efficiency

Abstract

The most important investigations on liquid weeping and entrainment in plate columns with downcomers are reviewed. The formulae for calculating column plate efficiency under conditions of liquid weeping and entrainment have been derived on the basis of mass balance equations. The presented model is a generalization of the models of AIChE and Colburn. Sample results are shown graphically. The effect of liquid entrainment on tray efficiency predicted by the model is in agreement with experimental data of F N .
