醋酸越过油水界面的传递——界面扰动对传质速率的影响
-
摘要: 在类似湿壁塔的扩散槽中研究醋酸在正己烷和水之间的传递。利用激光全息干涉装置拍摄传质界面现象的全息图。分析界面扰动对传质速率的影响,并给出了传质增强因子的关联式。Abstract: The transfer process of acetic acid from the hexane phase to the water phase was studied in a diffusional cell which is similar to a wetted wall column.The holograms of interfacial phenomena were taken by using a laser interferometry system,The effect of interfacial turbulence on mass transfer rate was analysed and the correlation equation for predicting enhancement factor of mass transfer coefficient was given.
