Abstract
La presente invención se refiere a proceso mejorado para la obtención de hexano normal de alta pureza, que involucra dos etapas primordialmente, una hidrogenación catalítica seguida de una destilación fraccionada; caracterizándose el proceso porque comprende un mezclado en línea de una corriente de hidrógeno con una de hidrocarburos que contiene hexano normal, sometiendose a un precalentamiento hasta 140 grados C y a un calentamiento hasta 210 grados C, enseguida se envía la corriente a un reactor de hidrogenación, donde se efectúa la reacción a temperatura de 140 a 275 grados C, presión de 20 a 75 Kg/cm cuadrado abs., espacio velocidad de 0.5 a 2.0 seg. -1 y lecho catalítico a base de níquel-molibdeno soportado en alúmina, el efluente de la reacción se enfría en dos etapas, posteriormente pasa a un separador de alta presión y despues a un agotador para eliminar los gases remanentes, donde estos son condensados y enviados a un separador final, del que se obtienen dos corrientes, una que se envía a la atmósfera y otra que se mezcla en línea con la corriente principal de salida del agotador, este efluente rico en hexano normal se alimenta a una columna fraccionadora en la que se lleva a cabo una destilación a presión atmosferica para obtener por el fondo de la misma una corriente de hidrocarburo que contiene una alta concentración de hexano normal básicamente.The present invention relates to an improved process for obtaining high purity normal hexane, which involves two stages, primarily a catalytic hydrogenation followed by fractional distillation; the process being characterized in that it comprises in-line mixing of a hydrogen stream with a hydrocarbon stream containing normal hexane, undergoing a preheating up to 140 degrees C and a heating up to 210 degrees C, the stream is then sent to a hydrogenation reactor, where the reaction is carried out at a temperature of 140 to 275 degrees C, pressure of 20 to 75 Kg / cm abs square, speed space of 0.5 to 2.0 sec. -1 and a nickel-molybdenum-based catalyst bed supported on alumina, the reaction effluent is cooled in two stages, then it passes to a high pressure separator and then to an exhauster to eliminate the remaining gases, where these are condensed and sent to a final separator, from which two streams are obtained, one which is sent to the atmosphere and the other which is mixed in line with the main outlet stream of the exhauster, this normal hexane-rich effluent is fed to a fractionating column in the that a distillation is carried out at atmospheric pressure to obtain at the bottom of the same a hydrocarbon stream that contains a high concentration of normal hexane basically.
