Corrosion Inhibitors
US Patent:
2007015, Jul 5, 2007
Filed:
Dec 29, 2005
Appl. No.:
11/323838
Inventors:
David Trahan - Lafayette LA, US
Joseph Neathamer - Gretna LA, US
Joseph Neathamer - Gretna LA, US
International Classification:
C09K 3/00
US Classification:
252388000
Abstract:
In general the current invention relates to corrosion inhibitors useful in water-based (aqueous) heat transfer fluids. More particularly, the present invention can be used for protecting ferrous and non-ferrous metal surfaces used in the construction of water-based (aqueous) heat transfer systems such as engine blocks and radiators. The invention particularly applies to a blend of corrosion inhibiting agents that can be added to water or water-glycol or other suitable liquid in a circulating or static heat transfer system to protect metal surfaces from corrosion attack. When used in an aqueous solution the unique blend of corrosion inhibiting agents provides flash corrosion protection of ferrous and non-ferrous surfaces during operation and after the treated aqueous fluid is drained away provides atmospheric corrosion protection of the ferrous and non-ferrous surfaces. The invention further relates to a variety of other practical and industrial applications such as engine coolant corrosion inhibition, dyno fluid corrosion inhibition, and metal working corrosion inhibition applications. The corrosion inhibitor includes several components 1) a dicarboxylic acid component comprising decanedoic and dodecanedoic and one or more C10-C12 dicarboxylic acids or salts of these acids, 2) an oxyalkylated carboxylate imidazoline preferably produced from carboxylate fatty acid and amine, 3) organophosphonic acid or amine salts of the organophosphonic acid and 4) a secondary or tertiary alkanolamine organic acid salting agent. The corrosion inhibitors of the present invention provide improved corrosion protection as compared to conventional inhibitors and provide surprisingly improved corrosion protection as compared to inhibitors containing only a single mono-carboxylic acid or blend of monocarboxylic and dicarboxylic acids or salts of these acids. The corrosion inhibitor of the present invention preferably contains no nitrite, nitrate, or silicate salts.
Method And Composition To Remove Iron And Iron Sulfide Compounds From Pipeline Networks
US Patent:
7855171, Dec 21, 2010
Filed:
Oct 16, 2008
Appl. No.:
12/288149
Inventors:
David O. Trahan - Lafayette LA, US
International Classification:
C11D 7/36, C11D 3/30
US Classification:
510188, 510247, 510222, 510228, 510288, 510363, 510401, 510431, 510435, 510436, 510467, 510480
Abstract:
The present invention comprises an iron complexing mixture and method of using same wherein beneficial performance and natural gas pipeline cleaning methods are employed. The synergistic improvement of combining two water-soluble metal complexing agents, THPS and IDS, prove to offer advantages in performance over the individual use of either chemical.

International Classification:
C09K 3/00
US Classification:
252390000
Abstract:
This invention relates in one aspect to a composition for inhibiting corrosion, such as flash rust, on metal surfaces. The composition described can include an organic acid component or a salt thereof, an azole component, an imidazoline component, a basic amine component, a phosphonate component, and a carrier including water and an alcohol such as glycol. The composition can also include surfactants, defoamers, buffers and other components as well. In another aspect, the invention relates to a method for treating metal surfaces to inhibit corrosion, comprising the steps of mixing, diluting and contacting or otherwise applying the above composition to the metal surface by spraying, dipping, coating or other effective means.
Oxygen Scavenging Solutions For Reducing Corrosion By Heat Stable Amine Salts
US Patent:
5686016, Nov 11, 1997
Filed:
Oct 10, 1995
Appl. No.:
8/541435
Inventors:
Ray R. Veldman - Houston TX

David Trahan - Lafayette LA
International Classification:
C09K 1500, C10G 1900
US Classification:
25218828
Abstract:
The formation of amine or glycol degradation products in solutions used to remove acid gases or water from hydrocarbon or inert streams is reduced by adding to the solution an oxygen scavenger in which the effective component is an oxime of the formula: ##STR1## Mixed with a quinone promotor in which R. sub. 1 and R. sub. 2 are the same or different and are selected from hydrogen or lower alkyl groups of one to six carbon atoms. The addition of the quinone promotor increases the reactivity with oxygen at lower temperatures. The compound may also be as a corrosion inhibitor in gas treating or processing equipment.
Gas Treating Solution Corrosion Inhibitor
US Patent:
6299836, Oct 9, 2001
Filed:

Assignee:
Coastal Chemical Co., L.L.C. (A Louisiana limited liability company)
International Classification:
C23F 1108, C09K 332
US Classification:
422 7
Abstract:
Corrosion in aqueous alkanolamine, physical solvents, or combination of alkanolamine and physical solvent solutions used to remove acid gases from natural gas, synthetic gas, or light hydrocarbon streams can be reduced by addition of mixtures of oxygen scavengers or mixtures of oxygen scavengers and sodium molybdate. The oxygen scavengers must be promoted to reduce metal surfaces in contact with the solutions to a more passive, harder, and insoluble form at the operating temperature of the treating system. The sodium molybdate provides additional passivation especially in the imperfections on the surface of the metal where corrosion accelerates.
