Experimental investigation on dispersed phase holdup in an L-shape pulsed packed extraction column

Progress in Nuclear Energy, 2021
Abstract In this study, the dispersed phase hold-up has been investigated in a pilot plant of a new type of extraction column entitled “L-shaped pulsed packed extraction column” by using two liquid systems of toluene/acetone/water and n-butyl/acetone/water in the presence of mass transfer in two directions.

Ultrasonic technique for dispersed-phase holdup measurements

Industrial & Engineering Chemistry Research, 1987
Mesure du temps de transit d'un train de pulsations ultrasonores, dans une colonne d'extraction liquide-liquide. Un modele de moyenne temporelle permet d'evaluer la retenue de la phase dispersee a partir du temps de transmission global des pulsations sonores.

Dispersed phase holdup and mass transfer in liquid pulsed column

Bioprocess Engineering, 1998
Dispersed phase holdup and drop velocity relative to the continuous phase are of fundamental importance in the development and operation of pulsed columns. Pulsed columns find application as biochemical reactors and in liquid-liquid extraction. The paper presents experimental data and its analysis covering dispersed phase holdup, slip velocity and mass

Dispersed‐phase holdup in a rotating disk extraction column

AIChE Journal, 1961
AbstractA study has been made of the effect of column geometry and flow condition upon the dispersed‐phase holdup in an rotating disk type of extraction column. Variables investigated were stator opening, disk diameter, compartment height, rotor speed, and flow rates of the dispersed and continuous phases.

Dispersed phase holdup and drop size distributions in reciprocating plate columns

The Canadian Journal of Chemical Engineering, 1983
AbstractThe paper covers an experimental and theoretical investigation of the dispersed phase holdup and drop size distribution for gas‐liquid and liquid‐liquid counter‐current flow in reciprocating plate columns provided with plates having small hole size and free area. The response of the reciprocating plate column is similar to that of liquid‐pulsed

Parametric study on dispersed phase holdup and axial drop size distribution in a pulsed disc and doughnut extraction column

, 2020
A parametric study of the dispersed phase holdup, specific power consumption (P) and axial drop size distribution (ADSD) in a pulsed disc and doughnut column have been carried out with 30% Tri-Butyl Phosphate- 0.01 M nitric acid system.
