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.
