Abstract：The development of mass transfer in the system of vapor-liquid-liquid three-phase distillation from trays was introduced, the effects of the hydrodynamic conditions e.g. vapor velocity and ratio of liquid to vapor loading and physical properties of liquid phase, including surface tension, interfacial tension, viscosity or dispersion viscosity, density, relative volatility etc. and the volume ratio of oil to water on mass transfer were discussed systematically,the influence of the second liquid on mass trans...

Key words：mass transfer; three-phase distillation; tray
