En este trabajo se desarrolla un modelo del TEP. Para ello se seleccionaron los modelos de caja gris los cuales presentan ventajas con respecto a las clásicas técnicas de modelado que son los modelos de conocimiento y los modelos totalmente empíricos. Primero se obtienen modelos empleando balances de masa y energía, para ello se definen varios parámetros y se realizan algunos supuestos. Luego, a partir de datos del proceso, y con el empleo del MatLab® se obtienen modelos empíricos. La combinación de todos los modelos obtenidos da lugar al modelo de caja gris final y objetivo general del presente trabajo.]]></p></abstract>
