    摘要: Methods for inhibiting the corrosion of metals in contact with an aqueous system are provided. The method of inhibiting corrosion includes maintaining effective amounts of (1) an amino acid-based polymer, such as a polyaspartic acid compound, and (2) a dispersible and/or soluble tin compound in the aqueous system. The corrosion inhibiting components of the treatment may be added simultaneously or separately into the water of the aqueous system, i.e., provided either in a single treatment product or as separate products. Such a corrosion inhibiting method may optionally also include adding a polycarboxylic acid chelating agent and/or a carboxylate/sulfonate functional copolymer to the aqueous system.

    摘要: The present invention provides an operation method of a plant which has a low-pressure feed water heater, a deaerator and a high-pressure feed water heater sequentially arranged in a feed water pipe reaching a steam generator from a condenser, and leads high-temperature feed water to the steam generator, wherein an oxidant is injected onto a surface of a structural material from an oxidant injection line in order to form a film that suppresses an elution of an element constituting the structural material such as the feed water pipe, the low-pressure feed water heater, the deaerator and the high-pressure feed water heater, which come in contact with the high-temperature feed water, and a corrosion suppression substance is further introduced from a corrosion suppression substance introduction line in order to deposit the corrosion suppression substance on a surface of the structural material in which corrosion accelerated by a flow of the feed water occurs.

    摘要: Corrosion inhibitors and methods for inhibiting or reducing corrosion are provided. The corrosion inhibitors include one or more niobate containing compounds. The corrosion inhibitors may be added to an aqueous system and inhibit the corrosion of a surface contained in the aqueous system. Illustrative examples of suitable niobate compounds are potassium niobate, ammonium niobate, and ammonium niobate oxalate.
