Abstract
In the search for new energetic alternatives biodiesel appears however its main source of raw material, vegetable oils, has a high cost when compared to fossil fuels. The use of waste cooking oils becomes attractive due to its low cost and, the optimization of biodiesel production processes makes this biofuel more economically competitive. Therefore, the main objective of this study is to carry out an exergetic and thermoeconomical analysis of the biodiesel production process from waste cooking oil, to locate the largest losses in the system and minimize them. Thus the mass, energy and exergy balance of the system were performed, obtaining the destroyed exergy of the system. Then, two objective functions were established in order to optimize the process. The results showed that the biodiesel production process studied was able to be optimized, generating a profit of $ 137,04 per second for a mass flow rate for waste cooking oil of 206 kg.s-1 and an oil/methanol ratio of 5 /1.
