Study of the fusel oil distillation process kansas gas service bill pay

Fusel oil is a byproduct obtained from bioethanol distilleries, composed of a mixture of higher alcohols such as isoamyl alcohol, isobutyl alcohol, and others. This study aimed to evaluate the industrial distillation process of fusel oil to obtain isoamyl alcohol using the Aspen Plus simulator, considering fusel oil as a mixture of nine components. Fusel oil samples collected in Brazilian industrial mills were analyzed by gas chromatography. An investigation of phase equilibrium (vapor–liquid equilibrium and liquid–liquid equilibrium) was carried out for the components involved in this mixture. Three configurations for the fusel oil separation process were proposed. The best design with minimum total annual cost (TAC) resulted in a recovery of 99.53% of isoamyl alcohol of product containing the isomers isoamyl alcohol (0.818 w/w) and active amyl alcohol (0.178 w/w). Dynamic control of this configuration was investigated, and the results show that reasonable control performance can be achieved.

… Therefore, based on those reports, the esterification mechanism proceed via the protonation of acetic acid by a proton donated from Brönsted acid sites, IL/MIL101(Cr) surface, forming protonated carboxylic acid intermediate, as shown in Schemes 2. This protonated intermediate then interacts with amyl alcohol generating the corresponding ester, amyl acetate, and water.Esterification of acetic acid with n-butanol (molar ratio 1:1) at 110 °C with 3 g of catalyst per mol of acetic acid for 5 h 60[41]70 HPW/MIL-101 The reaction was carried out over 0.05 g catalyst at 120 °C for 1 h using acetic acid to n-butanol molar ratio 1:1. 92.3 [42]HPW/MIL-101 0.2 g of catalyst, 0.1 mol of n-hexanol, and 0.1 mol of acetic acid at 110 °C for 6 h 58.3[45]HSO 3-MIL-101(Cr) HCl Esterification of n-butanol and acetic acid (1:1 M fraction) using 3 g of the catalyst (specified in the graph) per mole of reactant at 70 °C for 375 min. 40[45]S/MIL-101 0.3 g of catalyst, 0.1 mol of n-hexanol, and 0.1 mol of acetic acid at 110 °C for 5 h. …
