Flooding rates, dispersed phase hold‐up, hold‐up profile and drop‐size distribution were investigated in rotating disc and Oldshue Rushton 0.10 m diameter, 18 compartment columns with toluene‐water as the liquid‐liquid system. The axial dispersed phase hold‐up and the mean drop size in both contactors varied significantly with column height. The hold‐up profiles were correlated by semi‐theoretical models.
