In order to dehydrate the azeotropic solution from column B to produce anhydrous ethanol (min. 99.3 % w/w), three main technologies are commercially available: azeotropic distillation with cyclohexane, extractive distillation with ethylene glycol and adsorption with molecular sieves.
Hydrated ethanol is sent to the molecular sieves, where anhydrous ethanol is produced, and the diluted alcoholic stream from them is recycled to column B.
lters, settlers and molecular sieves, among others) were represented as component splitters, due to the lack of more adequate blocks in the simulator database.
