Energy balance analysis of the Brazilian alcohol for flex fuel production

This work refers to a case study on sugar cane mill from Sao Paulo State, in Brazil. It will be analysed the financial benefit acquired through sugar cane bagasse usage as energy source, studying the transformation of this inlet into electrical power, highlighting the greenhouse gas emissions throughout the manufacturing processes of sugar and alcohol. Also, a relationship between power generated and gases emitted will be established and a financial analysis of the project cash flow through the analysis of net present value (NPV), internal rate of return (IRR), and payback will be done. The high profitability calculated on Santa Candida Mill was evaluated, which becomes even greater when implementing the cogeneration system. This one may also consider the sale of surplus energy and carbon credits as two more products to sell to the plant.
