Diseño y construcción de un Deshidratador por Absorción con Tamices Moleculares para la obtención de Alcohol Anhidro

Abstract

The design an d construction of a molecular ab sorption dryer for obtaining anhydrous alcohol was performed in order to substantially reduce the percentage of water in ethanol to increase their alcohol content, the aforementioned equipment serves in the professional field, training and educatinal syste m, at Laboratory of Industrial Process, Sciences Faculty at ESPOCH. For design, was made some laboratory test varying the temperature and pressure of the feed to the column, these are 120°C and 40 PSI; therefore, the machine has a dehydration tower with a diameter of 11 cm, a capacity of 9,5 L, an internal bed 100 cm and 15 cm at the top and bottom for in put and output feed needed to ab sorb from 3,5 to 20% water in ethanol, a preheater works with a temperature of 120°C essential to raise the enthalpy of th e steam, and a condenser supplied with 25 °C water which transforms alcohol anhydrous liquid into vapor state. As a result a dehydrator ethyl alcohol was obtained with a yield of 86,6% and an efficiency of 92,9%, with positive results indicate that we can raise the alcoholic strength to reach 99,5% by weight, on a time of 20minutes. It is recommended to use the dehydrator in the laboratory for future research complementing the theoretical to the practical.
