TLDR
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.About:
