Simulación de una destilación alcohólica mediante fermentación de la cáscara de banano (cavendish) para la obtención de bioetanol rectificado.

Abstract

In Chemical Engineering, simulation is considered a feasible tool for solving common problems in chemical processes; this allows its application to be carried out correctly in the development of products that require computational validation. The banana (Musa Cavendish) represents up to 95% of sales. The peel of this fruit is rich in fiber (50 g/100g), which is why it is called an energetic material, becoming an optimal raw material for industrial processing. The objective of the project is to take advantage of the commonly unused organic waste, with an amount of 17.5 kg in three repetitions of a fractional distillation to verify if there is variation in the results of obtaining bioethanol, for its development the alcoholic fermentation process is used. anaerobically through the use of the Saccharomyces Cervisiae yeast that helps in the transformation of this organic waste, taking advantage of the properties it has and providing innovative ideas. The collected samples were obtained from the “El Cisne” farm located in the El Cambio parish of the El Oro Province. The process is carried out through fractional distillation on the equipment of the Unitary Operations laboratory where the results have been verified in the software. DWSIM, using the thermodynamic model of Raoult's law that consists of ideal mixtures to obtain the mole fractions of the components of interest, the program considers the Chemsep as a tool to apply the operational system of the distillation column, the data obtained through of experimentation and bibliographic compilation were used for a qualitative analysis with the purpose of obtaining the degrees of alcohol seeking that their values resemble those of the simulation to verify if its implementation in the development of the mentioned product is feasible. We have the results obtained from the simulation of processes agree with the experimental values with a value of 0.8233 in mole fraction of pure ethanol, verifying that the process used is appropriate for the reuse of this raw material whose results will be used for future research.
