Resumen
En el trabajo se realiza el análisis de la posibilidad de desarrollar instalaciones de la industria
de la caña de azúcar como biorrefinería mediante la integración de sistemas tecnológicos de
productos derivados y coproductos integrados a industrias azucareras en el poblado de
Covadonga, Cienfuegos; con el fin de mejorar la economía del país. Se realizó una extensa
búsqueda bibliográfica con vistas a tener un mayor conocimiento relacionado con el tema
debido a que en Cuba no se cuenta actualmente un complejo industrial con estas
características. Para ello se toman en cuenta tres alternativas: la desviación del jugo de los
filtros del central, para introducirlo al proceso fermentativo de obtención de etanol, la obtención
de ésteres a partir de los aceites de fúsel y los alcoholes de mal gusto de la destilería y como
tercera alternativa está la integración de las dos primeras. Se identificaron las dos instalaciones
en estudio y se determinaron las corrientes de los procesos mediante balances de masa y
energía. Se diseñaron los equipos a instalar para las nuevas propuestas, con ayuda del
HYSYS. Se realizó el análisis económico de cada una de ellas por separado y guiándose por
metodologías estudiadas en las que fue necesario utilizar como herramienta fundamental el
programa computacional Microsoft Excel. De los resultados obtenidos se elaboran conclusiones
y recomendaciones para preparar los estudios previos inversionistas para llevar a cabo esta
transformación.
This work was done by analyzing the possibility of developing industrial facilities as sugar cane biorefinery systems through the integration of technology products and integrated co sugar industries in Covadonga, located in Cienfuegos,to improve the country's economy. We performed an extensive literature search in order to enhance knowledge related to the topic, because currently, there is not an industrial complex with these featuresin Cuba. This will take into account three alternatives: the deviation of the juice of the plant filters, to add it to the fermentation process of ethanol production, the production of esters from fusel oils and alcohols tacky distillery and as a third alternative we have the integration of both. Two installations were identified in the study and were determined by processes of mass and energy balances; equipment to install was designed for the new proposals, using the HYSYS software .An economic analysis of each of them was also realized separately by guiding us for studied in which methodology Economic analysis was performed for each of them separately and it was guided bystudied methodologies in which it was necessary to usethe computer program Microsoft Excel as a basic tool. From the obtained results, conclusions and recommendations were made to prepare the previous investment studies to carry out this transformation.
