From the bottom of column B1 is withdrawn a nearly pure water stream, named phlegmasse, hydrated ethanol is produced on top of column B, and a side stream, containing most of the higher alcohols, is also withdrawn from column B (Dias 2008; Junqueira 2010).
The production of hydrated ethanol is performed using the distillation con?
Phlegmasse is the bottom stream of column B1, and hydrated ethanol is produced on top of column B.
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.
Vinasse and phlegmasse ethanol content <200 ppm Meirelles (2006) Amount of fusel oil per ethanol produced 0.2 % (v/v) Garcia (2008) Hydrated ethanol purity 93 wt% Mantelatto (2010) Molecular sieves
