TLDR
In this paper, fixed adsorptive distillation is used to enhance azeotropic IPA-water mixture with an interbed of adsorbent filled of silica gel, and the results show that this method can pass the aizotropic point; the higher the feed composition of column I as well as the high the ratio of flow is, the higher purity of the second column product is.About:

Economic comparison between azeotropic distillation and different hybrid systems combining distillation with pervaporation for the dehydration of isopropanol
TL;DR: In this paper, an economic analysis was performed comparing different processes for the dehydration of isopropanol/water, and it was found that the hybrid system distillation-pervaporation with ceramic membranes was the most interesting process from economic point of view and could lead to a saving in total costs of 49% compared to azeotropic distillation.
