%X Resumen (en_US) Background: Process simulation has been extensively used in recent years to design, evaluate or optimize processes, systems and specific operations of the chemical industry and its related disciplines. Currently, CHEMCADˋ constitute one of the most used process simulators because of the great number of chemical and petrochemical processes that can be simulated. Method: The simulation of the production process of styrene via catalytic dehydrogenation of ethyl-benzene is carried out by using the process simulator CHEMCADˋ version 5.2.0, in order to determine the composition and mass flow-rate of each process involved in the production, as well as the main operating parameters of the equipment used. Two sensitivity studies were carried out: firstly, the influence of the temperature and pressure values applied at the LLV Separator on the amounts of ethyl-benzene and styrene to be obtained by the intermediate and top currents of this equipment; secondly, the influence of the operating pressure of the Distillation Column No. 1 (benzene-toluene column) on the quantity of ethyl-benzene and styrene obtained at the bottom stream. The simulating software MATLABˋ version 7.8.0 was used to process the results obtained. Results: Around 9234.436 kg/h of styrene is obtained in the last distillation column with 99.6% purity. Additionally, it was found that the water is the main impurity found on this stream, which represents 0.35% of the weight. Conclusions: The LLV Separator must operate at a low temperature (5 每 10 oC) and at a relatively high pressure (10 bar), whereas the Distillation Column No. 1 must work at a pressure near atmospheric (1.0 bar), or preferably under vacuum conditions in order to obtain the highest yields of styrene and ethyl-benzene. Resumen (es_ES) Contexto: la simulaci車n de procesos se ha venido utilizando extensivamente en los 迆ltimos aˋos con el prop車sito de diseˋar, evaluar u optimizar procesos, sistemas u operaciones espec赤ficos de la industria qu赤mica y sus ramas afines. Uno de los simuladores de procesos m芍s empleados en la actualidad es el CHEMCADˋ, mediante el cual se pueden simular un gran n迆mero de procesos qu赤micos y petroqu赤micos. M谷todo: se lleva a cabo la simulaci車n del proceso de producci車n del estireno a partir de la deshidrogenaci車n catal赤tica del etilbenceno, utilizando el simulador de procesos CHEMCADˋ versi車n 5.2.0., con el fin de conocer la composici車n y el flujo m芍sico de cada una de las corrientes de proceso, as赤 como tambi谷n los principales par芍metros de operaci車n de los equipos utilizados.
