Propose an Empirical Model for Mean Drop Size in a Mixer-Settler Extractor with Anionic Surfactant

In this investigation, several experiments have been performed with a single stage horizontal mixer-settler. A video technique has been used in order to measure the drop size in the mixer-settler by a digital camera. The experiments carried out in various surfactant (Sodium Dodecyle Sulfate) concentrations, hold-ups and impeller speeds. For various surfactant concentrations, have been proposed an empirical model for mean drop size. These correlations have a good agreement with experimental data. Also the proposed correlations were compared with Desnoyer and Lee and Soong’s models where little deviation from Desnoyer model was found.
