Abstract

Reiv.1 Un método para suprimir la corrosión de una superficie metálica corrosible que está en contacto con una corriente de agua en un sistema de agua, caracterizado porque el método comprende: a) Introducir en la corriente de agua una primera dosis de carga de un inhibidor de corrosión en cantidades suficientes para proporcionar una película estable de Tin (IV) sobre la superficie metálica, en donde la primera dosis de carga se introduce en la corriente de agua durante un primer periodo de tiempo y la corriente de agua tiene una primera concentración de inhibidor de corrosión durante el primer periodo de tiempo; b) Después del primer periodo de tiempo, mantener una segunda concentración de inhibidor de corrosión en la corriente de agua durante un segundo periodo de tiempo, en donde la segunda concentración es menos del 25% de la concentración del inhibidor de corrosión durante el primer periodo de tiempo; y c) Después del segundo periodo de tiempo, introducir en la corriente de agua una segunda dosis de carga del inhibidor de corrosión durante un tercer periodo y a una tercera concentración mayor que la segunda concentración, siendo la tercera concentración suficiente para mantener o re-estabilizar las porciones de la película estable de Tin (IV) sobre la superficie metálica.
