Dispersed phase holdup and volumetric mass transfer coefficient were measured in a reciprocating plate column with high porosity packing in interplate spaces of the column and the performance was compared with that of the column without packing. The data and its analysis show substantial increase in the dispersed phase holdup and in the interfacial area to give an enhancement of 4 to 5 times in the volumetric efficiency of the column with the added packing.

Influence of added packing on the volumetric efficiency in a Karr column

Bioprocess Engineering

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.
