The general features of the two types of operation of a counter-current liquid-liquid extraction spray column are reviewed, i.e. loose-bed operation, which has been known for some time, and compact bed operation, which was not discovered until a few years ago. The ratio between the relative velocity of the two phases [formula] and the velocity of motion of a drop in an infinite medium [formula] is investigated, which depends on the retention coefficient of the dispersed phase hold-up and the physical properties of the fluids, especially their viscosity. This function, which was derived from the results of tests on fifteen pairs of liquids, can be used to predict flooding and the hydrodynamic behaviour of a liquid-liquid extraction column.On...
