Predicción del equilibrio vapor-líquido de la mezcla acetato de etilo-etanol usando la ecuación de estado de Peng Robinson

Resumen

El presente artículo tiene como propósito mostrar la predicción del equilibrio vapor-líquido de una mezcla no ideal mediante modelos termodinámicos como lo es la ecuación de Peng-Robinson para el cálculo de los coeficientes de fugacidades de los componentes en estado gaseoso, y el modelo de Van Laar para hallar los coeficientes de actividad de los componentes en estado líquido. Los resultados se validan mediante el uso del simulador comercial Aspen Plus y la herramienta online “VLE-Calc”, obteniendo resultados similares con los valores experimentales de la mezcla binaria.

Palabras clave: equilibrio vapor-líquido, coeficiente de fugacidad, coeficiente de actividad, Peng Robinson, Van Laar, Azeótropo
