En la actualidad no se cuenta con un modelo de simulación para el estudio de la generación de vapor en la destilería de etanol estudiada.  Objetivo: Obtener un modelo de simulación en Aspen Hysys de la etapa de generación de vapor que permita la evaluación de la operación y el análisis de modificaciones futuras.  Materiales y Métodos: El modelo de simulación se desarrolló en Aspen Hysys v10.0. Se seleccionó el paquete de propiedades Peng Robinson para los gases de combustión a bajas presiones y NBS Steam para el agua pura. La composición del petróleo crudo (PCM 1400) se seleccionó en función de lo reportado por varios autores.  Resultados y Discusión: Se comprobó que el petróleo crudo simulado es similar al real. Se verificó el modelo de simulación con un error relativo menor de 2,5 %. Se obtuvo una eficiencia del generador de vapor de 86,3 %, un índice de generación de 16,04 kg vapor/kg combustible y un flujo de aire de 5 388 kg/h. Se evaluó la influencia de la variación del flujo de aire sobre la temperatura de los gases a atmósfera y la potencia requerida por el ventilador.  Conclusiones: El modelo de simulación obtenido representa adecuadamente el sistema, lo que permite evaluar el comportamiento de las principales variables del proceso ante diferentes escenarios sin realizar modificaciones directas al proceso.]]></p></abstract>

Currently there is no simulation model available to study the steam generation in the ethanol distillery studied.  Objective: To obtain a simulation model in Aspen Hysys from the steam generation stage that allows operation evaluation and future modifications analysis.  Materials and Methods: A simulation model was developed in Aspen Hysys v10.0. Peng Robinson property package was selected for low pressure flue gases and NBS Steam for pure water. The composition of crude oil (PCM 1400) was selected based on several authors reports.  Results and Discussion: Simulated crude oil was found to be similar to real one. The simulation model was verified with a relative error less than 2.5%. Steam generator efficiency of 86.3% was achieved, a generation rate of 16.04 kg steam/kg fuel and an airflow of 5 388 kg/h. airflow variation influence on gases temperature and the power required by the fan was assessed.  Conclusions: The simulation model adequately represents the system, allowing to evaluate the main process variables behavior in different scenarios without making direct modifications to the process.]]></p></abstract>
