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 TBPOK 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 ketonewater cyclohexanewater and 20TBPOK0.05 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.
