Patent number: 10683576Abstract: An additive comprising one or more C3-C12 hydroxycarboxylic acids and/or one or more C3-C12 hydroxycarboxylic acid salts may be added to an aqueous system having galvanized metallurgy or a carbon steel surface in an effective amount to passivate a galvanized coating on the metallurgy or to decrease white rust formation or other types of corrosion upon the galvanized metallurgy or carbon steel surface in an aqueous system. In a non-limiting embodiment, the C3-C12 hydroxycarboxylic acid or the C3-C12 hydroxycarboxylic acid salt additive may utilize the zinc in the galvanized coating to achieve passivation. The passivation may occur while the system is shut down or in service. The aqueous system may be or include a cooling tower, a cooling water system, and combinations thereof. The additive may be used with or in the absence of a phosphorous-containing compound.Type: GrantFiled: March 23, 2018Date of Patent: June 16, 2020Assignee: Baker Hughes, a GE company, LLCInventors: Mary Jane Legaspi Felipe, Timothy Ray Underwood, Albert Sidney Dunn, David N.

Publication number: 20140241939Abstract: A new corrosion inhibitor composition containing a carboxylic acid and its water soluble salts with zinc can be used for corrosion inhibition on the carbon steel pipe and heat exchangers in industrial cooling water. This new composition of matter contains less carboxylic acid and Zn2+ than previous formulations and still have >90% corrosion inhibition. It is disclosed that the synergistic effect of combining the carboxylic acid with very small amounts of Zn results in a product with good corrosion inhibition properties that is more environmentally friendly than the current common phosphonate corrosion inhibitors; particularly for use in cooling water applications.Type: ApplicationFiled: February 25, 2014Publication date: August 28, 2014Applicant: BAKER HUGHES INCORPORATEDInventors: Haiping Lu, Bing Bing Guo, David N.
