Abstract

LA PRESENTE INVENCION SE REFIERE A LA INTEGRACION TERMICA EN UN PROCESO DE ALQUILACION/TRANSALQUILACION QUE IMPLICA LA ALQUILACION DE UN SUSTRATO AROMATICO CON UN AGENTE ALQUILANTE C SUB,2} C SUB,4} JUNTO CON LA SEPARACION PARA RECUPERAR UN PRODUCTO AROMATICO MONOALQUILADO Y LA TRANSALQUILACION, EN FASE GASEOSA, DE UN PRODUCTO POLIALQUILADO. SE INTRODUCEN UNA CARGA DEL COMPUESTO AROMATICO Y UN AGENTE ALQUILANTE C SUB,2} C SUB,4} EN LA ZONA DE REACCION DE ALQUILACION UTILIZADA PARA ORIGINAR UN PRODUCTO ALQUILADO. EL EFLUENTE DE LA ZONA DE REACCION DE ALQUILACION PASA INICIALMENTE A TRAVES DE UN CONJUNTO DE INTERCAMBIADORES TERMICOS. DESDE ALLI, EL EFLUENTE DE LA ALQUILACION LLEGA AL INTERIOR DE LA PRIMERA ZONA DE SEPARACION UTILIZADA PARA PRODUCIR UNA FRACCION DE PUNTO DE EBULLICION INFERIOR QUE COMPRENDE EL SUSTRATO AROMATICO, QUE PUEDE SER RECICLADO A LA ZONA DE REACCION DE ALQUILACION, Y UNA FRACCION DE PUNTO DE EBULLICION SUPERIOR QUE COMPRENDE UNA MEZCLA DE COMPUESTOS AROMATICOS MONOALQUILADOS Y POLIALQUILADOS. ESTA FRACCION DE PUNTO DE EBULLICION INFERIOR REGRESA EN PRIMER LUGAR A TRAVES DE PARTE DEL CONJUNTO DE INTERCAMBIADORES TERMICOS INTERMEDIOS PARA RECICLARSE DENTRO DE LA ZONA DE ALQUILACION. LA FRACCION DE MAYOR PUNTO DE EBULLICION DE LA PRIMERA ZONA DE SEPARACION PASA A UNA ZONA DE SEPARACION SECUNDARIA PARA PRODUCIR UNA SEGUNDA FRACCION DE PUNTO DE EBULLICION INFERIOR QUE COMPRENDE EL PRODUCTO MONOALQUILADO DESEADO Y UNA FRACCION DE PUNTO DE EBULLICION SUPERIOR QUE COMPRENDE EL PRODUCTO POLIALQUILADO. AL MENOS UNA PORCION DE LA FRACCION POLIALQUILADA DE PUNTO DE EBULLICION SUPERIOR LLEGA, A TRAVES DE PARTE DEL CONJUNTO DE INTERCAMBIADORES TERMICOS, AL INTERIOR DE UNA ZONA DE REACCION DE TRANSALQUILACION QUE CONTIENE UN TAMIZ MOLECULAR DE CATALISIS DE LA TRANSALQUILACION QUE TIENE EFECTO EN CONDICIONES DE FASE LIQUIDA PARA PRODUCIR LA DESPROPORCION MOLECULAR DE LA FRACCION POLIALQUILADA HASTA ORIGINAR UN PRODUCTO DE DESPROPORCION QUE PRESENTA UN REDUCIDO CONTENIDO DE COMPUESTOS AROMATICOS POLIALQUILADOS Y UN MAYOR CONTENIDO DE COMPUESTOS AROMATICOS MONOALQUILADOS.
