Simulação - Chemsep-coco e produção de Etanol a partir de aguardente obtido da Cana-de-açúcar

Abstract

In the current context of growing concerns in the health sector, the demand for ethanol for use as an antiseptic is growing. The valorization of agro-industrial waste for the production of bio-products from renewable sources is a topic of great interest. In the case of the production of ethanol from a biological source, conventional processes have low production costs, based on the socio-economic development in Mozambique, the initiative arises to reuse brandy for the production of ethanol from the abundant raw material in the country that is sugar cane. In this context, this project is conducted with the aim of generating technological information by simulating and producing sugarcane brandy by means of fractional distillation. Where a fractional distillation column was built, whose figure and dimensions of the column are presented in the annex, after the construction, the test phase with water began, where evaporation was carried out, which consisted of eliminating leaks or losses present in the distillation column. In terms of production, the brandy samples come from the Maragra sugar factory, in the district of Manhiça, in the province of Maputo. The physical characterization of the samples was carried out before and after the distillation operation in order to analyze the influence between the alcohol content and the density in ethanol and the energy consumption was recorded for each test, in order to make a comparison with the simulated part. A part of the work was carried out with the aid of a commercial simulator ChemSep-COCO (CAPE OPEN to CAPE OPEN). Eight (8) samples of brandy were analyzed through physical analysis and later established relationships between them. With the results obtained from the tests, the production of ethanol in the experimental part obtained, on average, an alcohol content of 87.4ºGL and an energy consumption of 1.5107 kW. The result of the process simulation presented an average of 94.26ºGL and an energy consumption of 3.2935 kW. There was a need to optimize the distillation operation and the other operations that make up the ethanol production process.( TRADUÇÃO NOSSA)
