Abstract

LA RELACION DE CARGA DE UNA MEZCLA DE UN ANTIDISOLVENTE DE CERA QUE CONTIENE OXIGENO Y UN AROMATICO, POR DISOLVENTE QUE CONTIENE ACEITE DE HIDROCARBUROS, SE PUEDE AJUSTAR FACILMENTE PONIENDO EN CONTACTO LA MEZCLA CON UNA MEMBRANA DE PERVAPORIZACION NO POROSA, QUE CONSTA DE UNA RESINA DE CAMBIO IONICO DE ELEVADO PESO MOLECULAR, QUE TIENE ATOMOS DE CARBONO EN EL ESQUELETO Y QUE LLEVA COLGANDO UN GRUPO ACIDO, MEMBRANA QUE SE HA PROVISTO DE CONTRAIONES DE UNA SAL DE POTASIO O DE FOSFONIO CUATERNARIO, QUE CONTIENE GRUPOS HIDROCARBILO, CADA UNO DE LOS CUALES CONTIEN 4 ATOMOS DE CARBONO POR LO MENOS, MIENTRAS SE MANTIENE UNA CAIDA DE PRESION A TRAVES DE DICHA MEMBRANA DE PERVAPORIZACION PARA FORMAR (I) UN SISTEMA DE RETENCION QUE TIENE UN CONTENIDO DECRECIENTE DE ANTIDISOLVENTE DE CERA QUE CONTIENE OXIGENO, Y UN INFILTRADO QUE TIENE UN CONTENIDO CRECIENTE DE ANTIDISOLVENTE DE CERA QUE CONTIENE OXIGENO. DE ESTE MODO, EL OPERADOR DE UNA PLANTA DE DESCERADO PUEDE AJUSTAR FACILMENTE LA RELACION DECARGAS DE SU DISOLVENTE DEPENDIENDO DE LAS CARACTERISTICAS DEL ACEITE QUE SE DESCERA.
