  • Patent number: 6800594
    Abstract: An environmentally friendly corrosion inhibiting formulation for the oil-water interface of pipe lines and oil well drilling systems which is prepared pursuant to a process including the steps of reacting an acid selected from the group consisting of a fatty acid anhydride and a 21 carbon dibasic acid with an amine or imidazoline to form a corrosion inhibitor consisting essentially of a fatty acid derivative; dissolving the inhibitor in a fatty acid oil or ester selected from the group consisting of soybean oil or methyl soya ester; adding water dispersing agents consisting of sulfonates and a long chain ethoxylated alcohol; and adjusting the viscosity with an alcohol comprising isopropanol.

  • Patent number: 6797197
    Abstract: The present invention provides a method of treating boiler and condensate water by the addition of an effective amount of a hydroxyamine-acid ester treatment reagent or an all-in-one treatment composition comprising a hydroxyamine-acid ester. Modification of a hydroxyamine to a hydroxyamine-acid ester generally reduces the odors of the amine while providing a means to formulate the composition into a solid form. The ester typically decomposes at conditions in the boiler to release the hydroxyamine to treat the boiler water. Other components used to treat boiler water and condensate related problems may be formulated with the hydroxyamine-acid ester to form the all-in-one treatment composition.

  • Patent number: 6706214
    Abstract: A composition and process for inhibiting the corrosion of metallic substrates is revealed. The process utilizes an aqueous treatment solution comprising chitosan which has been reacted with an additive selected from the group consisting of phosphorus-containing compounds and sulfur-containing compounds and mixtures thereof. More preferably, the phosphorus-containing compound is a phosphonic acid and the sulfur-containing compound is a mercapto, thio, or thienyl containing compound or a mercapto functional silane. The composition and process are particularly useful in providing corrosion protection for aluminum and aluminum alloys.

  • Patent number: 6645399
    Abstract: Compositions and methods have been discovered for inhibiting corrosion of metals, particularly iron alloys, in contact with fluids, either hydrocarbons, alcohols, or aqueous fluids, employing mercaptoalcohols. The mercaptoalcohols should have at least one water solubilizing hydroxyl group. In particular, suitable mercaptoalcohols have the formula: (HS)n—R—)(OH)m where R is a straight, branched, cyclic or heterocyclic alkylene, arylene, alkylarylene, arylalkylene, or hydrocarbon moiety having from 1 to 30 carbon atoms; n and m each independently averages from 1 to 3; and the heteroatom in the heterocyclic moiety substituent, if present, may be N, O, S and/or P. Preferred mercaptoalcohols include 2-mercaptoethanol, 2-mercaptopropanol, 1-mercapto-2-propanol, and 2-mercaptobutanol, in part because they are soluble in many fluids. These corrosion inhibitors show improved inhibition of both generalized and localized corrosion, specifically in high shear and high flow environments.
