Based on the importance of drops' behavior in liquid-liquid extraction, the maximum sauter mean drop diameter has been investigated and correlated in a counter-current spray extraction column with two chemical systems. Spargers were set of nozzles in all experiments. Studying the effects of several parameters on drops size, some correlations were estimated by the last available version of software “Eviews”. Finally, the best empirical correlation was selected based on lowest error and highest conformity with the experimental data. It’s notable that, in this paper, the maximum sauter mean drop diameter was investigated and correlated for first time in a spray extraction column. Comparing final selected correlation with experimental data, it’s observed that the correlation mentioned above has an error about 4.22% with empirical data that shows the good accuracy of this correlation.
