Abstract

Un método para tratar sistemas de agua para inhibir la corrosión en acero no galvanizado y otros componentes metálicos en el sistema de agua, que comprende: agregar un polímero a base de aminoácidos o su sal soluble en agua, al agua en el sistema de agua; agregar ácido hidroxifosfonoacético o su sal soluble en agua, al agua en el sistema de agua; agregar un segundo ácido fosfónico o su sal soluble en agua, al agua en el sistema de agua, donde la etapa de agregar proporciona una concentración activa de 3 ppm – 50 ppm del polímero a base de aminoácido o su sal soluble en agua, una concentración activa de 3 ppm – 50 ppm del ácido hidroxifosfonoacético o su sal soluble en agua, y una concentración activa de 2 ppm – 20 ppm del segundo ácido fosfónico o su sal soluble en agua para inhibir la corrosión; y donde no se añaden zinc o molibdeno al agua en el sistema de agua.A method of treating water systems to inhibit corrosion on non-galvanized steel and other metallic components in the water system, comprising: adding an amino acid-based polymer, or its water-soluble salt, to the water in the water system; adding hydroxyphosphonoacetic acid, or its water soluble salt, to the water in the water system; adding a second phosphonic acid, or its water-soluble salt, to the water in the water system, where the adding step provides an active concentration of 3 ppm - 50 ppm of the amino acid-based polymer or its water-soluble salt, a concentration active 3 ppm - 50 ppm of the hydroxyphosphonoacetic acid or its water soluble salt, and an active concentration of 2 ppm - 20 ppm of the second phosphonic acid or its water soluble salt to inhibit corrosion; and where zinc or molybdenum is not added to the water in the water system.
