This study has investigated the effects of operational parameters on the mean drop diameter (d(32)), the dispersed phase holdup (phi) and the slip velocity (V-s) in uranium (VI) stripping of the loaded Alamine 336 using ammonium carbonate (0.64 M) by a horizontal pulsed sieve plate column. The main operational and physical parameters are the continuous and the dispersed phase flow rates, the pulsation intensity, the density, the continuous and the dispersed phase viscosities and the interfacial tension. Experimental results showed that an increase in the pulsation intensity led to a decrease in phi and d(32), and an increase in the phase flow rates cause an increase in both phi and d(32), although the impact of the flow rates on the d(32) was much milder than the pulsation intensity. Also, it was observed that the V-s increase by increasing the pulsation intensity and the phase flow rates. Based on the experimental results and dimensional analysis, three experimental-theoretical correlations for predicting d(32), phi, and V-s are proposed. The Average Absolute Relative Errors (AARE) of these parameters were 9.90%, 14.45%, and 8.58%, respectively, signifying their accuracy and usefulness for horizontal pulsed sieve plate column scaling up.
