Abstract

PROCEDIMIENTO DE ISOMERIZACION DE LOS COMPUESTOS AROMATICOS CON OCHO ATOMOS DE CARBONO EN PRESENCIA DE HIDROGENO EN EL QUE SE AÑADE A LA CARGA ANTES DE SU INTRODUCCION EN EL REACTOR DE ISOMERIZACION R POR LA LINEA (1) UNA MEZCLA QUE CONTIENE COMPUESTOS CUYO PUNTO DE EBULLICION ESTA APROXIMADAMENTE ENTRE 80 Y 135°C QUE COMPRENDE AL MENOS UNA PARAFINA CON OCHO ATOMOS DE CARBONO, AL MENOS UN NAFTENO CON OCHO ATOMO DE CARBONO, AL MENOS BENCENO Y AL MENOS TOLUENO. ESTAS APORTACIONES SON EFECTUADAS POR UN RECICLADO GARANTIZADO POR LA LINEA (6) O POR LA ADICION DE COMPUESTOS RECIENTES POR LA LINEA (11) O TAMBIEN POR UNA COMBINACION DE COMPUESTOS RECIENTES Y RECICLADOS GARANTIZADA POR ESTAS DOS LINEAS (6 Y 11). SE ASEGURA UNA ADICION DE HIDROGENO POR LA LINEA (15).
