Illustrative examples are presented which demonstrate that in spite of the fact that the same fundamental thermodynamic quantities EL and f," are involved in the definition of the rate of mass transfer and in the definitidn of the-vaporizahbn efficiency, a non-zero. finite and positive set of vapori
## Ah&act -In packed columns large differences occur in the wetting of the particles and especially in the refreshing of the liquid 011 the wetted particles due to gradients in surface tension of the liquid/gas interface. Mass transfer rates may die, with a factor 2. In a column packed with Berl s
## Abstract The pressure drop and mass transfer efficiency for two‐phase flow in a structured packed column were simulated using a commercial CFD package, CFX version 10. The distillation of the methanol/isopropanol system was carried out in a 0.073 m diameter column, with an element composed of a
