In Colombia, the sugar obtained from the sugar cane fields is used not only as food, but also as raw
material to produce anhydrous fuel ethanol. The bioethanol production process takes place in three steps:
fermentation, distillation and dehydration, being the distillation step the more energy consuming. In
addition, the product obtained at the end of this stage affects directly the performance of the dehydration
step and therefore the final product quality. Hence, special attention must be paid to the distillation process.
