PROCESO DE OBTENCIÓN DE BIODIÉSEL A PARTIR DE AVUs: ANÁLISIS DIFERENCIAL DE COSTOS DE OPCIONES ÓPTIMAS DE INTEGRACIÓN ENERGÉTICA

Abstract

In this work, the best alternative design of Heat Exchange Network (HEN) applied to the process of esterification and transesterification with methanol to obtain biodiesel from waste vegetable oils (WVO) was selected through a differential economic analysis between the alternatives with and without HEN. Both options with heat integration presented a higher net present value (NPV) than those where no energy integration was applied, mainly due to the decrease in operating costs. The NPV for options 1 and 2 was US$ 29,821,901 and US$ 26,004,006, respectively. Therefore, Option 1 turned out to be the most economically convenient technological alternative.
