摘要
介绍了气液液三相精馏塔板传质性能研究的进展情况,讨论了气速、液气比等操作条件,表面张力、界面张力、液体的粘度或分散粘度、密度和相对挥发度等物系性质以及油水体积比等多种参数对传质效率的影响,探讨了第二液相的存在对传质的影响,文中的许多观点和建议对于优化精馏塔的设计具有重要的指导意义。
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 transfer efficiency was also investigated, a great deal of viewpoints and suggestions having been put forward in this paper are significant important for optimizing design of distillation tower.
