Obtenção de etanol líquido neutro a partir dos resíduos (cabeça e cauda) oriundos da fabricação de cachaça por processo de destilação convencional e assistido por micro-ondas para obtenção de álcool gel.

Abstract

With the advent of technological globalization, ideal for industrial companies is to process assessment (s) material (s) with your full time to educating the supply chain profitability and be more competitive in the market recovery. This study aimed to develop the process for recovery of waste (head and tail) deriving from the manufacture of cachaça to obtain neutral liquid ethanol by conventional distillation process and an innovative distillation process assisted by microwave, to obtain alcohol gel at 70 ° INPM. In this work , we studied the kinetics of processes destilatórios mixtures of wastes with concentration of 40°GL, 42.5°GL, 45GL°, 47.5° and 50°GL in both distillation systems, varying the temperature heating at 90°C, 92°C, 94°C, 96°C, 99°C and 100°C which defined parameters, such as temperature optimum heating systems, heating rate, ethanol alcoholic distillate yield and process, as well as adjusting the traditional formulation of obtaining ethanol from ethanol gel using waste. In the process distillatory using radiation microwaves as the heating agent, was used a microwave microdestilador developed for this purpose, keeping the same parameters as defined methodology to conventional distillation. Waste, liquid alcohol antiseptic gel extracted and ethanol produced were characterized by physical and physico-chemical as densitometry, ebuliometria, gas chromatography and viscometry. The results showed that the ethanol extract of the waste meets the technical specifications established by ANVISA ( National Health Surveillance Agency ) for ethanol antiseptic gel to 70°INPM ideal temperature range and work in both stills is 99°C - 100°C. Ethanol antiseptic gel , obtained from waste, presented physical and physical-chemical properties similar to ethanol gel and traditional terms of their cost / benefit ratio, showed significant economic advantage from the standpoint of cost material consumption and price of the product on the market compared to the traditional alcohol gel.
