Modeling of Mass Transfer of Non-spherical Drops in Liquid-liquid Extraction Columns

Document Type : Research Paper

Abstract

In this paper, mass transfer modeling of non-spherical drops, when the drops are a segment of an ellipse, was carried out. Predicted results obtained by the new and Handlos-Baron models and experimental data were compared. The dimensions of the non-spherical drops were optimized by using the experimental data. In this work, the Olney’s model using Klee & Treybal drop terminal velocity correlations were utilized to model the hydrodynamics of the column. Mass transfer of the column was also modeled using forward mixing, and the required drop sizes were obtained from experimental data. 95% confidence limits in predicting the plug flow number of transfer units    using Handlos-Baron and new model were calculated and the values of this parameter are 32.78% and 11.11% respectively.
