Abstract

UN METODO DE FILTRACION POR LECHO MIXTO Y DEMINERALIZACION PARA EXTRAER LAS IMPUREZAS SUSPENDIDAS DEL PRIMER AGUA DE REFRIGERACION EN UNA PLANTA ELECTRICA POR MEDIO DE UN DEMINERALIZADOR QUE DISPONE DE UN LECHO MIXTO FORMADO DE PARTICULAS DE RESINA CON INTERCAMBIO DE IONES Y CATIONES QUE TIENEN UNA ESTRUCTURA DE CAPA SUPERFICIAL TAL QUE LOS GRANULOS, VISTOS BAJO EXAMEN MICROSCOPICO, ESTAN ENLAZADOS ENTRE SI, SIENDO OPERADOS DE UNA MANERA SEGURA Y ECONOMICA MEDIANTE LAS CONDICIONES ESTABLECIDAS DEL PROCESO DE OPERACION, TALES COMO LA REGENERACION DEL DEMINERALIZADOR MEDIANTE EL RETROLAVADO Y EL PASO DE QUIMICO Y TAMBIEN MEDIANTE EL REEMPLAZO DEL DEMINERALIZADOR.
