Resumo

The raw materials used for the production of biodiesel can be vegetable oil, animal tallow or residual fat. Among them, the use of soybean oil stands out. The present study aims to analyze the exergy efficiency of the soybean oil pretreatment process of a biofuel plant in the state of Minas Gerais, with an installed capacity of 152 million liters/year of biodiesel. For that, the calculation of the chemical exergy and the physical exergy of the flows related to the process of refining the oil for biodiesel production was carried out. Plant operating parameters were in order to calculate the exergy efficiency of the process and the mass flow to perform the mass balance of the analyzed plant. The exergetic efficiency of the soybean oil pretreatment process was 88% and destroyed exergy or irreversibility of approximately 11%. Therefore, the yield of the chemical reactions of the process were satisfactory.
