水/乙二醇与水/二甘醇真空蒸馏的传质性能与流体力学特性研究

Study on the mass transfer and hydrodynamics of water/ethandioL and water/diglycol in vacuum distillation

本文探讨了两种混合工质:水/乙二醇、水/二甘醇在θ环小型填料塔中,采用不同回流比及塔操作压强对真空蒸馏过程传质分离效率与流体力学特性的影响。

Influence of varying reflux ratio and operating pressure of the two mixedworking media(ie,water/ethandiol,water/diglycol)in the θ—ring packedcolumn on the mass transfer property and hydrodynamics characteristic ofvacuum distillation
