This study aims to present experimental studies on the dispersion of immiscible liquids in agitated vessels for a range of liquids and geometries under both batch and continuous conditions. Preliminary experiments were first carried out in a small scale single –stage mixer-settler unit operating with the 20% TBP/OK, 0.05M nitric acid, uranyl nitrate system. This work was followed by measurements of drop size distribution in agitated liquid-liquid systems in 6 and 9 inches baffled and a 20 cm side square tank using six-flat bladed turbine type impellers. The drop size measurement technique employed fiber optic probes and photography. The liquid-liquid systems used for the measurements were methyl-iso-butyl ketone/water, cyclohexane/water and 20%TBP/OK/0.05 nitric acid. The volumetric fractions were 0.10, 0.15 and 0.20 Impeller speeds varied from 300 to 500 r.p.m. A correlation of the mean drop size for the cylindrical and square vessels under both batch and continuous conditions were established.
