Abstract
SE DESCRIBE UN PROCESO DE PRODUCCION DE ETERES TERCIARIOS (MTBE, ETBE, TAME, ETAE) EN EL QUE SE HACE REACCIONAR UN CORTE HIDROCARBONADO (1) DE CUATRO O CINCO ATOMOS DE CARBONO CON METANOL O ETANOL (2,3) EN UN REACTOR (6) Y DESPUES DE LA DESTILACION (C1) SE RECUPERAN LOS ETERES (11) Y UN DESTILADO (10). SE REALIZA UNA PRIMERA DESTILACION EXTRACTIVA DEL DESTILADO EN PRESENCIA DE UN SOLVENTE SELECTIVO (27) DE LOS HIDROCARBUROS OLEFINICOS EN UNA COLUMNA (CII) Y SE RECUPERA UNA FRACCION DE CABEZA (15) RICA EN HIDROCARBUROS SATURADOS Y UNA FRACCION DE COLA (18) RICA EN OLEFINAS, EN SOLVENTE Y EN ALCOHOL. SE SEPARAN LAS OLEFINAS (20) DEL SOLVENTE Y DEL ALCOHOL (24) POR UNA SEGUNDA DESTILACION EXTRACTIVA (CIII). LAS OLEFINAS SE ISOMERIZAN EN UN REACTOR DE ISOMERIZACION ESQUELETAL (5) Y EL ISOMERADO SE RECICLA (2) HACIA EL REACTOR (6). EL ALCOHOL Y EL SOLVENTE ESTAN SEPARADOS EN UNA COLUMNA DE ESTABILIZACION (CIV), EL ALCOHOL (26) SE RECICLA HACIA EL REACTOR DE SINTESIS (6) MIENTRAS QUE EL SOLVENTE(27) SE RECICLA HACIA CII. SE PUEDE REDUCIR LA TEMPERATURA DEL FONDO DE LA SEGUNDA COLUMNA (CIII) POR ADICION DE ALCOHOL FRESCO (4) O RECICLADO (34). APLICACION EN LOS ADITIVOS QUE AUMENTAN EL INDICE DE OCTANO DE LAS GASOLINAS.
