Viabilidade de geração de uma usina sucroalcooleira.

Abstract

This work has the objective to evaluate the feasibility of electric energy supply by the process of cogenerating with sugarcane bagasse. It will be observed the advantages of this activity for the Brazilian energetic matrix and society and environment and the entrepreneur. The cogenerating process by the sugarcane is efficient and sustainable considering environmental matters. It has big potential to complement the national energetic park, which is in current scenario, highly dependent on hydroelectric power plants, which are dependent on rainfall levels and correct topography. The cogeneration is not a new method in Brazil. It has been used for many years as an alternative to supply energy for the plants of sugar and ethanol, as long as their main input it is the bagasse prevenient from the sugarcane processing. The sugar and ethanol sector projects a high raise on the demand of sugar and ethanol, which means also a raise on sugarcane bagasse for energy production.This current work realizes a case study of a sugar and ethanol plant in Alagoas state, Brazil. It is evaluated the use of sugarcane bagasse on cogeneration of electric energy by its combustion. It is also shown the importance for the sugar and ethanol sector to sell the extra amount of energy produced to the energetic market.
