气相夹带对蒸馏塔板效率的影响

Effect of Vapor Entrainment on Distillation Tray Efficiency

本文给出了在完全泡沫状态或以泡沫为主的混合状态下进行蒸馏操作时包括气相夹带的板效率模型,导出了Lewis的第一、第二和第三种情况的板效率计算式,讨论了气相夹带对板效率的影响,并与FRI的实验值作了比较.

A distillation tray efficiency mode] including the effect of vapor entrain-ment was developed for the emulsion flow regime or froth flow regime operation under Lewis case 1, 2 and 3 conditions. The effect of vapor entrain-ment on tray efficiency was systematically investigated for the three cases. The calculated values by the model were in good agreement with FRI experimental data.
