Análise e desenvolvimento de projeto de uma indústria sucroalcooleira: usina Rio Doce

Abstract

The use of alternative energy sources to fossil fuels has been gaining importance in Brazil and in the world, in this scenario biomass has been highlighted as a renewable source of energy production. This work presents some reflections regarding the expansion of the sugarcane industry in Brazil, without disregarding the historical context of formation of the Brazilian territory and its relation with the sugarcane culture, the sugar and alcohol manufacturing processes are discussed. A market analysis was also carried out to visualize the feasibility of the implantation of a new plant in Brazil. In the study it was verified that the sugar and alcohol industry has great influence in Brazil and the sector can contribute in a relevant way to an efficient, profitable and sustainable production. Due to the climatic conditions, relief, soil and logistics, the city of Rio Claro was chosen for the development of the new plant, as a consequence of the current market prices, a production ratio of 80% of VHP sugar for export and 20% of hydrated alcohol for domestic consumption, and a milling capacity of 12,000 tons of sugarcane per day was established. With this, a simplified flow diagram of the process and a possible layout of the plant, which will be called the Rio Doce Plant, was constructed. From the mass balance achieved it is possible. Energy balance, energy integration, equipment design and financial analysis were performed. From the data obtained it was possible to infer that the enterprise is viable with an IRR of 10.27%.
