Pilot Design of a Distillation Column to Obtain Isoamyl Alcohol from Fusel Oil
Keywords:
Fusel oil, distillation, isoamyl alcoholAbstract
Brazil stands out internationally in the production of biofuels, especially ethanol, and its importance is commonly the subject of several studies. In the sugar-alcohol sector, the distillation process is essential for the good quality of the final product. However, from this operation, a residue that does not have high economic value in its natural state, the fusel oil, is also produced. The present work aims to design a pilot distillation column to obtain the isoamyl alcohol present in this by-product to add economic value to it. The McCabe-Thiele method was selected for dimensioning the distillation column, and the main results consisted of a distillation efficiency of 36%, using 8 trays, and a purity of isoamyl alcohol analyzed by chromatography of 92,2 %. Therefore, the work presents an alternative for the use of this important by-product.
