    Abstract: A composition and method of inhibiting corrosion and white rust on metal components in a water system. The composition preferably comprises an amino-acid based polymer (most preferably a polyaspartic acid or a salt thereof), hydroxyphosphonoacetic acid, and a second phosphonic acid (preferably a phosphonocarboxylic acid), and does not require the use of regulated metals. The composition is effective even in the presence of biocides. A preferred method of inhibiting white rust comprises adding an amino-acid based polymer or hydroxyphosphonoacetic acid or both to the water system. A preferred method of inhibiting corrosion or white rust comprises adding an amino-acid based polymer, hydroxyphosphonoacetic acid, and a phosphonocarboxylic acid to the water system. Preferably the active concentrations are at least 3 ppm each of the amino-acid based polymer and hydroxyphosphonoacetic acid when added to a volume of water in the water system.

    Abstract: Corrosion inhibitor compositions are provided that can include a mixture of one or more transition metals, one or more organic phosphates, one or more inorganic phosphates, optionally a dispersant, and hydroxyphosphono acetic acid and/or salts thereof. Methods of mitigating or inhibiting corrosion of housing or conduits containing aqueous mediums are also disclosed. The methods can include the steps of pretreating the metal conduit with a mixture of one or more transition metals, one or more organic phosphates, one or more inorganic phosphates, and hydroxyphosphono acetic acid, introducing an aqueous medium into the metal conduit, and injecting a mixture of one or more transition metals, one or more organic phosphates, one or more inorganic phosphates, and hydroxyphosphono acetic acid and/or salts thereof into the aqueous medium.

    Abstract: A synergistic composition comprising a THP salt and a biopenetrant, in which the biopenetrant comprises a polymer of an unsaturated carboxylic acid or a copolymer of an unsaturated carboxylic acid with a sulphonic acid, said polymer or copolymer being terminated by a mono- or diphosphonated unsaturated carboxylic acid group or having such monomers incorporated into the polymer backbone. This composition acts synergistically to enhance the biocidal efficacy of the THP salt against both planktonic (free-swimming) and sessile (attached) bacteria, and also acts synergistically to enhance the efficacy of the THP salt in the dissolution of iron sulphide scale.

    Abstract: The present invention relates to a method of treating an aqueous system containing or in contact with metal sulphide scale. The method comprises adding to said system, separately or together, sufficient of a synergistic mixture comprising a THP+ salt, an aqueous solution of a strong acid (and optionally a source of nitrogen) to provide a solution containing from 0.1% to 30% by weight of the THP+ salt at a pH of less than about 1.0. The scale is contacted with said solution, (thereby dissolving at least part of said scale in said solution) and the dissolved scale is withdrawn from the system.
