INTEGRATED SYSTEM FOR INCREASING ETHANOL RECOVERY AND
CO-PRODUCTION OF ISOAMYL ALCOHOL, INTEGRATED PROCESS FOR
INCREASING ETHANOL RECOVERY AND CO-PRODUCTION OF ISOAMYL
ALCOHOL, AND PRODUCTS THUS OBTAINED
ENERGY AND FUELS
The technology enables higher ethanol recovery and production of isoamyl alcohol without
major changes in the process
The growth in the demand for ethanol production enabled an increase in options for more profitable uses of by-products generated
in the process, such as fusel oil. For every 1000 liters of produced ethanol, 1 to 11 liters of fusel oil are generated. However, mills
have not been taking advantage of this by-product that contains not only ethanol but also isoamyl alcohol.
The technology allows the integration of a system in the conventional ethanol distillation process without changing its structure by
simply attaching a new module to the existing plant. This enables fusel oil distillation increasing ethanol recovery and the production
of high purity isoamyl alcohol. This kind of alcohol is often used as a reagent and solvent in the food, paint and varnishes, plasticizers
and fragrance industries.
