摘要：

The flooding behaviour of a 150-mm diameter Wirz-II extraction column has been investigated for six different liquid-liquid systems. Normally, flooding occurred by phase inversion but when the density difference was low could also occur by entrainment of dispersed-phase drops at the continuous-phase exit. Empirical expressions for flooding velocities and holdup at flooding are derived in terms of the operating variables, column geometry and physical properties of the liquid systems.
