PROCESSOS E ANÁLISES FÍSICO-QUÍMICAS NA FABRICAÇÃO DE ETANOL

Abstract

Due to the constant increase in the demand for ethanol as an alternative fuel, the sugar and alcohol industry requires professionals who understand more the productions process. The sugar-alcohol unit need professionals that know well how that physical-chemical processes are important to help for a better quality and yield of this produce. This work has an intention to guide in the decision-making and adjustments in the production process. Flowchart with production stages and physicochemical reactions involved: sugar cane, weighing, cane sampling, milling, broth treatment, evaporation, fermentation, centrifugation, distillation and produced ethanol are described. Thus, this technical guide can clarify, subsidize and substantiate the activities that are already carried out, besides being able to contribute to the improvement of the learning of future professionals related to the area of chemistry and the like, who are already practicing professions in this area and students who are interested to know more the content presented here. Another possibility, it is good subjects for teachers prepare their students by STEM during high school.
