Abstract
SE DESCRIBE UN PROCESO DE SEPARACION DE UNA MEZCLA DE ETER, DE ALCOHOL Y DE HIDROCARBUROS, EN EL QUE SE INTRODUCE LA MEZCLA A SEPARAR EN UNA PRIMERA COLUMNA DE DESTILACION, DE DONDE SE RECOGE EN CABEZA LA CASI TOTALIDAD DE LOS HIDROCARBUROS Y SE RECOGE EN EL FONDO EL ETER PURIFICADO, Y SE TRASIEGA LATERALMENTE DE ESTA PRIMERA COLUMNA DE DESTILACION AL MENOS UNA FASE QUE SE ENVIA A UNA SEGUNDA COLUMNA DE DESTILACION, DE DONDE SE RECOGE EN EL FONDO ALCOHOL Y EN CABEZA UNA MEZCLA DE ALCOHOL, DE ETER Y DE HIDROCARBUROS, QUE SE RECICLA HACIA DICHA PRIMERA COLUMNA DE DESTILACION. ESTE PROCESO PUEDE EN PARTICULAR SER UTILIZADO PARA SEPARAR MEZCLAS DE ETIL TERO-BUTIL ETER (ETBE), DE ETANOL Y DE HIDROCARBUROS C{SUB,4}. ESTE PROCESO PUEDE ESTAR INTEGRADO EN UN PROCESO DE FABRICACION DE ETER, EN EL QUE PARTICULARMENTE EL ALCOHOL SEPARADO POR LA SEGUNDA COLUMNA DE DESTILACION SE RECICLA HACIA EL REACTOR DE ETERIFICACION. LA PRIMERA COLUMNA DE DESTILACION PUEDE SER SUSTITUIDA POR UNA COLUMNA DE DESTILACION CATALITICA.
