Dispersed phase hold-up in rotary disc contactor

Abstract

The present study in Rotary Disc Contactors, an attempt has been made to develop a new correlation for the direct estimation of dispersed phase hold-up with the knowledge of known operating system variables and also to estimate the different regions of effective operation in terms of rotor critical speed. New generalized correlation involving Froude Number, phase flow rates, modified property group along with those of geometry factor is proposed for both no solute transfer as well as mass transfer conditions. A large bank of published literature data from 13 different sources (1248 data points with 14 liquid systems) with a wide range of variables, along with those of author's data (291 measurements with four liquid systems) were used. The proposed correlations are far more accurate and simple to use, than those of previously reported.
