IIT Madras

A numerical technique for the estimation of the true mass transfer coefficient in extraction columns

The Chemical Engineering Journal

Liquid-liquid mass transfer has been experimentally studied for the kerosene (dispersed)-water (continuous) system in a reciprocating-plate column, using benzoic acid and n-butyric acid as solutes. The effect of the flow rates of the phases, the agitation rate of the plate stack, the perforation diameter and free area of the plate and the mass transfer direction have been investigated. Correlations for volumetric and mass transfer coefficients have been proposed in terms of power dissipation rate and the physical properties of the system. The mass transfer coefficient is compared with the predictions of the drop models to establish the extent of internal mobility of the dispersed phase droplets. © 1994.

Liquid-liquid mass transfer in a reciprocating-plate column

Mass transfer for kerosene-water system with benzoic acid and n-butyric acid as solutes has been studied in a reciprocating plate column at different operating conditions including the agitation rate of the plate stack, the plate geometry, the flow rates of the phases and the direction of mass transfer. Apparent and true concentration profiles for the dispersed and the continuous phase along the length of the column were generated, taking axial mixing of the phase into consideration. It is noticed that high agitation rate for the plate stack and low free area for the plate give rise to large difference between the apparent and true values. These observations also agree with the data obtained for carbon dioxide - water system studied in a reciprocating plate column. © 1993 Springer-Verlag.
