A method of reducing oxygen-induced corrosion in an aqueous system comprising: contacting the aqueous system comprising water, oxygen, and a glycol, with an effective amount of an oxygen scavenger composition to reduce oxygen-induced corrosion therein , the oxygen scavenging composition comprising: at least one sulfite compound, at least one transition metal salt selected from the group consisting of chloride salts, sulfate salts, and combinations thereof, wherein the transition metal salt comprises an ion transition metal selected from the group consisting of nickel, cobalt, manganese, and combinations thereof, and at least one stabilizer selected from the group consisting of citric acid, ethylenediaminetetraacetic acid, glycolic acid, acetic acid, ethylenediamine, N, N-diethylethylenediamine , diethylenetriamine and salts of these stabilizers, and combinations of these stabilizers and salts thereof; and reducing oxygen-induced corrosion in the aqueous system by scavenging oxygen with the oxygen scavenging composition. |
