Compositions and methods for inhibiting corrosion of metallic surfaces in contact with an aqueous medium such as copper, copper alloy, and steel surfaces of an open recirculating cooling water system. In certain embodiments, an aromatic triazole having an anionic substituent bonded to a nitrogen atom of the triazole (ANST) is used as the corrosion inhibitor. In other embodiments, the corrosion inhibitor is a reaction product of an aromatic triazole and an aldehyde (ATA).

Nitrogen substituted aromatic triazoles as corrosion control agents

Treatment compositions for neutralizing acidic species and reducing hydrochloride and amine salts in a fluid hydrocarbon stream are disclosed. The treatment compositions may comprise at least one amine with a salt precipitation potential index of equal to or less than about 1.0. Methods for neutralizing acidic species and reducing deposits of hydrochloride and amine salts in a hydrocarbon refining process are also disclosed. The methods may comprise providing a fluid hydrocarbon stream and adding a treatment composition to the fluid hydrocarbon stream. The treatment compositions used may have a salt precipitation potential index of equal to or less than about 1.0 and comprise either water-soluble or oil-soluble amines.
