Ferramenta de gestão de perdas e custos das impurezas minerais e vegetais na produção de etanol.

Abstract

The expansion of the sugarcane crop and its technological evolution has been a constant concern of the sugarcane industry, optimizing the production of ethanol and sugar competitively. Technological innovations in the agricultural and industrial areas have increased the competitiveness of the sugar and alcohol industry in the country, evidenced by the reduction of production costs, which have become a great differential. In this context the sugarcane harvest in Brazil is in evolution with respect to the traditional manual harvesting system of whole cane with previous firing for the mechanized harvest of cane chopped without burning of the cane field. These changes lead to changes in the ethanol and sugar manufacturing processes that need to be monitored, aiming at cost reduction and optimization. Ethanol is one of the main derivatives of sugarcane, with a significant portion of its use as fuel and its burning helps to reduce the gases that cause global warming. The evaluation of the variables that affect costs and efficiency in the plants need objectivity to reduce costs. In this work a tool was developed, using worksheets elaborated using Excel software version 2017 and the java application with SQlite database capable of quantifying the daily financial losses caused by the impurities of plants and minerals. With the use of this tool it is possible to evaluate the direct reduction in ethanol productivity, sending this information by mobile application in mobile phones and smartphones, producing faster and more efficient evaluations, to reduce costs in the ethanol production process. The study was validated through studies of sugarcane harvesting data obtained from an unidentified distillery, located in Paraíba, using methodologies from the sugar mill itself. The way the data obtained was evaluated is innovative and promising for the reduction of costs related to impurities in plants and minerals.
