Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA LA OBTENCION DE UN BENCENO PURO Y UN TOLUOL PURO A BASE DE UN PRODUCTO PREVIO QUE CONTIENE HIDROCARBUROS AROMATICOS. EL PRODUCTO PREVIO SE LIBERA DE GASES EN UNA ETAPA (1) DE PROCESO DE ESTABILIZACION DESTILATIVA, CON LO CUAL EL PRODUCTO PREVIO ESTABILIZADO SE SEPARA EN PRODUCTOS INTERMEDIOS RICOS EN BENCENO Y RICOS EN TOLUOL, DE MODO QUE LOS PRODUCTOS INTERMEDIOS RICOS EN BENCENO Y EN TOLUOL SE GUIAN A UNA ETAPA (2) DE PROCESO DE DESTILACION DE EXTRACCION Y SE APLICAN EN UN FONDO DIFERENTE SEPARADO DE UNA COLUMNA (4) DE DESTILACION EXTRACTIVA. SE EXTRAE UNA MEZCLA A PARTIR DE BENCENO PURO, TOLUOL PURO Y MEDIOS DE EXTRACCION DEL SUMIDERO (3) DE LA COLUMNA (4) DE DESTILACION DE EXTRACCION Y EL MEDIO DE EXTRACCION SE SEPARA EN UNA ETAPA (5) DE PROCESO DE DESTILACION DE BENCENO PURO Y DE TOLUOL PURO PARA LA GUIA DE NUEVO A LA ETAPA (2) DEL PROCESO DE DESTILACION DE EXTRACCION. SE CARACTERIZA DE TAL MODO, QUE LA ETAPA (1) DEL PROCESO DE ESTABILIZACION DESTILATIVA SE ENRIQUECE PARA LA SEPARACION DEL PRODUCTO PREVIO EN EL PRODUCTO INTERMEDIO EN LAS ZONAS RICAS DE BENZOL Y TOLUOL Y DE MODO QUE POR UNA PARTE EL PRODUCTO INTERMEDIO RICO EN BENCENO SE ADICIONA DIRECTAMENTE A PARTIR DE LA ETAPA (1) DEL PROCESO DE ESTABILIZACION DESTILATIVA DE LA ETAPA (2) DEL PROCESO DE DESTILACION EXTRACTIVA. POR OTRA PARTE EL PRODUCTO INTERMEDIO RICO EN TOLUOL ANTES DE LA AFLUENCIA A LA ETAPA (2) DEL PROCESO DE DESTILACION EXTRACTIVA SE EMPOBRECE EN CUANTO A LA COMPOSICION DE COMPONENTES DE ALTA EBULLICION EN LA ETAPA (6) DEL PROCESO DE DESTILACION PREVIA.
