A population-balance-equation model is employed for the analysis of liquid-liquid extraction columns. This model considers drop breakage, coalescence, and exit phenomena for the drop phase caused by drop-drop and drop-continuous phase interactions. Drop breakage and coalescence rates are employed fr

β¦ Synopsis
Drop
size distributions and dispersed phase holdups in a multistage vibrating disk column (MVDC) have been investigated.
The drop sizes and holdups are strongly affected by the wave-form of disk vibration. The drop size distributions, mean diameters and holdups are well correlated in terms of dimensionless groups containing the instantaneous maximum speed of disk vibration.
The interfacial area can be enlarged by the disk vibration by as much as 70-80 times of that without vibration at the highest vibrating speed range investigated here.

This paper reports measurements of droplet sizes and holdup in liquid-liquid systems in a 2 in. dia. reciprocating plate extraction column, in the absence of mass transfer. The Sauter mean droplet diameter was found to depend on the product of plate amplitude and frequency and on the system propert
The residence time of fluid elements in a control volume of any chemical process has a direct effect on the process efficiency. This effect is more important in liquid-liquid extraction where the residence time of the dispersed-phase droplets determines not only the extraction/reaction time but also
