Abstract
SE DESCRIBE UN PROCESO PARA PRODUCIR ALUMINA EN EL QUE LA EFICACIA DE LA CALCINACION SE MEJORA MUCHO UTILIZANDO UN SISTEMA DE INTERCAMBIO TERMICO TOTAL EN EL QUE SE CALIENTA PROGRESIVAMENTE EL HIDRATO DE ALUMINA EN UNA PLURALIDAD DE FASES DE INTERCAMBIO TERMICO A TEMPERATURAS SUBSIGUIENTEMENTE MAS ELEVADAS QUE SE APROXIMAN A LAS TEMPERATURAS DE CALCINACION Y, A CONTINUACION, SE INTRODUCE EN UN CALCINADOR PARA LA CONVERSION FINAL EN ALUMINA. LA ALUMINA CALCINADA SE ENFRIA EN UNA PLURALIDAD DE FASES DE INTERCAMBIO TERMICO, CON UNA SENSIBLE CANTIDAD DE CALOR QUE SE TRANSFIERE DE LAS FASES DE ENFRIAMIENTO DE LA ALUMINA CALCINADA A LAS FASES DE CALENTAMIENTO DEL HIDRATO DE ALUMINA A UNA TEMPERATURA, EN CADA FASE, SOLO LIGERAMENTE SUPERIOR A LA TEMPERATURA DE UNA FASE DE CALENTAMIENTO O A LA QUE SE CONSUME EL CALOR EN DICHA FASE. SE PUEDE OBTENER UNA MAYOR EFICACIA DEL SISTEMA SECANDO PREVIAMENTE EL HIDRATO DE ALUMINA PARA ELIMINAR LA HUMEDAD SUPERFICIAL UTILIZANDO AIRE DEL SISTEMA. ADEMAS, SE PUEDEN UTILIZAR LOS GASES DE ESCAPE DEL CALCINADOR PARA LA COMBUSTION DE PRECALENTAMIENTO Y EL AIRE DE LA FLUIDIZACION PARA EL CALCINADOR.
