Abstract

UN METODO Y APARATO PARA REDUCIR LA CORROSION EN EL INTERIOR Y EXTERIOR DE UN DEPOSITO DE ALMACENAMIENTO DE COMBUSTIBLE. EN EL INTERIOR DEL DEPOSITO DE ALMACENAMIENTO DE COMBUSTIBLE SE COLOCA UN CONJUNTO DE ANODO GALVANICO RODEADO POR UNA CAPA DE GEL HIDROFILO. ESTE GEL ABSORBE EL AGUA PRESENTE EN EL COMBUSTIBLE DEL DEPOSITO DE ALMACENAMIENTO, IMPIDIENDO ASI QUE ESTE EN CONTACTO CON EL DEPOSITO. EL GEL HIDROFILO TAMBIEN ABSORBE LOS IONES METALICOS FORMADOS A MEDIDA QUE SE CONSUME EL ANODO. EL GEL HIDROFILO SE MANTIENE ALREDEDOR DEL ANODO POR MEDIO DE UN RECIPIENTE POROSO. EL ANODO, EL GEL HIDROFILO Y EL RECIPIENTE POROSO SE MANTIENEN DENTRO DE UN RECIPIENTE FLEXIBLE QUE PERMITE QUE EL AGUA Y EL LIQUIDO CONTENIDO DENTRO DEL DEPOSITO DE ALMACENAMIENTO DE COMBUSTIBLE ENTREN EN CONTACTO CON EL GEL HIDROFILO. EN UNA REALIZACION, EL GEL HIDROFILO INCLUYE UN MATERIAL DE POLIACRILAMIDA.
