A laser capillary spectrophotometric technique is used to study and quantify the dispersed phase mixing effects on the performance of a one liter continuous flow reactor for the cobalt-di-(2-ethylhexyl) phosphoric acid extraction system. Bivariate distribution data show that, as the RPM increases, the drop size and drop concentrations change from widely to narrowly distributed, the former tending toward small drop sizes and the latter tending toward higher concentrations. Comparisons between the Monte Carlo simulation model predictions and experimental results, using an aqueous film reaction model, indicates that the simulation predicts the size distribution closely, the Sauter mean diameter within 10% error, and the extraction efficiently within 15% error.
