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 softw...
