摘要：

Residence-time distribution of dispersed phase has been investigated in a 150-mm-diameter Wirz-II agitated extraction column for six different liquid-liquid systems of medium to low interfacial tension and small density difference, using a two-point transient tracer technique. The flow of the dispersed phase is described by a convective model, and drop velocities and constriction factors are calculated from measured residence-time curves and drop-size distributions. For design purposes, an empirical correlation is presented for the average constriction factor in terms of the agitator speed and density difference between the phases.
