| 摘 要：介紹了氣液液三相精餾塔板傳質(zhì)性能研究的進(jìn)展情況,討論了氣速、液氣比等操作條件,表面張力、界面張力、液體的粘度或分散粘度、密度和相對揮發(fā)度等物系性質(zhì)以及油水體積比等多種參數對傳質(zhì)效率的影響,探討了第二液相的存在對傳質(zhì)的影響,文中的許多觀(guān)點(diǎn)和建議對于優(yōu)化精餾塔的設計具有重要的指導意義。 |

| 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... |
