Abstract

LA INVENCION CONCIERNE A UN PROCESO DE DESHIDRATACION DEL DISOLVENTE QUE PROVIENE DE UNA OPERACION DE DESPARAFINADO DE HIDROCARBUROS. UN DISOLVENTE ORGANICO MIXTO HUMEDO (1), POR EJEMPLO UNA MEZCLA MEK/TOLUENO HUMEDA, ES DESHIDRATADO EN UNA PRIMERA ZONA DE DESTILACION (2). EL PRIMER DESTILADO RESULTANTE (10) ES PUESTO EN CONTACTO CON EL AGUA (14, 23), PARA FORMAR DOS FASES DONDE UNA (15), RICA EN DISOLVENTE ORGANICO, ES DEVUELTA (27) COMO REFLUJO A LA PRIMERA ZONA DE DESTILACION MIENTRAS QUE LA OTRA FASE (16), RICA EN AGUA, ES DESTILADA EN UNA SEGUNDA ZONA DE DESTILACION (17). EL PRODUCTO DE CABEZA (21) Y UNA PARTE (14) DEL PRODUCTO DE FONDO (24) DE LA SEGUNDA ZONA DE DESTILACION SON DEVUELTOS A LA ZONA DE CONTACTO ENTRE EL PRIMER DESTILADO Y EL AGUA. LA INVENCION SE APLICA AL DESPARAFINADO DE ACEITES LUBRIFICANTES.
