The first step is carried out in a pre-concentration distillation column (PDC) that concentrates bioethanol from 5–12% up to 92.4–94%wt. The second step is the ethanol dehydration up to concentrations above the azeotropic composition. Although extractive distillation presents relatively high energy costs, it is still the option of choice in case of large scale production of bioethanol fuel.
