Hydrodynamic features of centrifugal contactor separators: Experimental studies on liquid hold-up, residence time distribution, phase behavior and drop size distributions

► Experimental study on hydrodynamics of a centrifugal contactor separator. ► Hold-up mainly function of weir system and not flows (flows <100 mL/min). ► Residence time distribution model shows seven or more mixers in series with dead zone. ► Drop size distribution measurements with FBRM probe. ► Phase inversion measured.
