Abstract
Proceso de elaboracion de 1,2-dicloroetano comenzando a partir de un flujo de etano, donde: a) el flujo de etano es sometido a una oxideshidrogenacion catalítica que produce una mezcla de gases que contiene etileno, etano no convertido, agua y constituyentes secundarios; b) dicha mezcla de gases opcionalmente se lava y se seca, produciendo así una mezcla de gases seca; c) después de una etapa de purificacion opcional adicional, dicha mezcla de gases seca que comprende al flujo de productos derivado del reactor de cloracion R2 separada en la etapa e), es sometida a una absorcion A que consiste de la separacion de dicha mezcla de gases en una fraccion enriquecida con los compuestos que son más livianos que etileno que contienen parte del etileno (fraccion A) y en una fraccion F1; d) la fraccion A es desviada hacia un reactor de cloracion R1 en el cual la mayor parte del etileno presente en la fraccion A es convertido en 1,2- dicloroetano y el 1,2-dicloroetano obtenido es separado del flujo de productos derivado del reactor de cloracion R1; e) la fraccion F1 es sometida a una desorcion D1 que consiste en la separacion de la fraccion F1 en una fraccion de etileno agotado en compuestos que son más livianos que etileno (fraccion C) que es desviada hacia un reactor de cloracion R2, donde el flujo de productos derivado de este reactor se agrega a la mezcla de gases seca sometida a la etapa c) opcionalmente después de haber extraído el 1,2-dicloroetano formado, y en una fraccion F2; f) la fraccion F2 es sometida a una desorcion D2 que consiste en la separacion de la fraccion F2 en una fraccion enriquecida con etileno (fraccion B) y en una fraccion F3, que opcionalmente contiene al 1,2-dicloroetano formado en el reactor de cloracion R2 luego se extrae, si no ha sido extraído previamente, que es reciclada hacia la absorcion A, opcionalmente después de un tratamiento adicional destinado a reducir la concentracion, en la fraccion F3, de los compuestos que son más pesados que el etano; g) la fraccion B es desviada hacia un reactor de oxicloracion en el cual la mayor parte del etileno presente en la fraccion B es convertido en 1,2-dicloroetano, el 1,2-dicloroetano obtenido es separado del flujo de productos derivado del reactor de oxicloracion y opcionalmente se agrega al 1,2-dicloroetano formado en el reactor de cloracion R1 y opcionalmente al que se formo en el reactor de cloracion R2; y h) el flujo de productos derivado del reactor de oxicloracion, de cual se ha extraído el 1,2-dicloroetano, que opcionalmente contiene un flujo de etano adicional introducido previamente en una de las etapas b) a g), es reciclado opcionalmente hacia la etapa a) opcionalmente después de haber purgado los gases y/o después de un tratamiento opcional con el fin de eliminar los productos dorados contenidos en el mismo.
