Abstract

PROCESO DE SEPARACION DE ETILTERTIOBUTILETER A PARTIR DE MEZCLAS CON ETANOL. SE DESCRIBE UN PROCESO DE SEPARACION DE ETIL TERTIOBUTIL ETER A PARTIR DE MEZCLAS QUE FORMA CON EL ETANOL. ESTE PROCESO ESTA BASADO EN UNA DESTILACION HETEROAZEOTROPICA QUE PONE EN JUEGO AGUA COMO TERCER CUERPO ARRASTRADOR. APLICA DOS COLUMNAS DE DESTILACION, ACOPLADAS CON UN DECANTADOR EN CABEZA.EL ETANOL PURIFICADO ES RECOGIDO EN EL FONDO DE LA PRIMERA COLUMNA Y EL ETBE PURIFICADO, EN EL FONDO DE LA SEGUNDA COLUMNA. ESTE PROCESO DE SEPARACION PUEDE ESTAR INTEGRADO EN UNA UNIDAD DE PRODUCCION DE ETBE QUE COMPRENDE LA ETERIFICACION POR ETANOL DEL ISOBUTENO CONTENIDO EN UNA COPA C4 DE CRAQUEO POR VAPOR, DE CRAQUEO CATALITICO O DE DESHIDROGENACION DE ISOBUTANO. EL ETANOL SEPARADO DEL ETBE SE RECICLA ENTONCES EN LA ZONA DE ETERIFICACION.
