Abstract

En vista de la preocupación mundial por el aumento del consumo energético, así como, la aplicación de alternativas viables que permitan un mejor aprovechamiento de las fuentes energéticas disponibles, los residuos térmicos surgen como una alternativa energética en aplicaciones industriales en las cuales se generan. En este sentido, el presente trabajo analiza el potencial energético de los gases de combustión emitidos por una estación de compresión, los cuales pueden utilizarse como fuente de calor para un ciclo Rankine de potencia el cual opera con varios fluidos de trabajo incluyendo nueve de tipo orgánico y el dióxido de carbon (CO₂). Las simulaciones demostraron la capacidad de los fluidos de trabajo para incrementar la eficiencia energética de la instalación a partir de los gases de escape de la estacion de compresión, siendo que el tolueno y el CO₂ se destacan por presentar los mayores niveles de eficiencia, 21 y 20%, respectivamente. Con el objetivo de generación de potencia del ciclo, se concluye que los fluidos refrigerantes considerados en el análisis no son aptos para el ciclo en los niveles de temperatura evaluados.
