Resumen
Resumen: Debido al acelerado crecimiento poblacional a nivel mundial y por ende el alto consumo de insumos energéticos, la mayoría de ellos de origen fósil, surge la posibilidad de usar alternativas como la Jatropha curcas como insumo para procesos de conversión a biocombustibles. En este trabajo se desarrolló un análisis energético y exergético de cada una de las etapas de producción de biodiesel a partir del aceite de Jatropha y el uso de la biomasa en un ciclo Rankine para la producción de vapor y trabajo con el fin de determinar sus eficiencias y visualizar las irreversibilidades cada uno de ellos obteniendo resultados de eficiencia exérgetica de 29.49%, 99.43%, 87.6%, 62.14% y 71% para los proceso de extracción, esterificación, transesterificación, combustión de biomasa y proceso global respectivamente, así mismo se obtienen de indicadores de renovabilidad de 0.78, 0.99, 0.83, 0.55 y 0.55 para cada uno de ellos.
Abstract: Due to the rapid worldwide population growth and hence the high consumption of energy sources, most of them of fossil origin, raises the possibility of using alternatives such as Jatropha Curcas as input for biofuel conversion processes. This thesis develops an energy and exergy analysis of each stage of production of biodiesel from Jatropha oil and biomass combustion in a Rankine cycle for steam and work production in order to determine their efficiencies and display irreversibilities, exergetic efficiency results of 29.49%, 99.43%, 87.6%, 62.14% and 72% for extraction process, esterification, transesterification, biomass combustion and overall process respectively, also are obtained renewability indicators of 0.78, 0.99, 0.83, 0.55 and 0.55 for each of them.
