  • Method of use of a coating compound for liquid-fertilizer holding vessels, and liquid fertilizers
    Patent number: 5731032
    Abstract: In one aspect, am anti-corrosion treatment method of reducing internal corrosion of a liquid nitrogen fertilizer holding vessel comprising providing at least one quaternary-amine-comprising compound within the vessel. In another aspect, an anti-corrosion treatment method of reducing corrosion of a liquid nitrogen fertilizer holding vessel comprising: a) providing a substantially insoluble liquid film of a quaternary-amine-comprising compound over a volume of liquid nitrogen fertilizer within a steel vessel; and b) coating internal sidewalls of the steel vessel with the quaternary-amine-comprising compound as the volume of liquid fertilizer increases and decreases within the vessel. In another aspect, an anti-corrosion mixture comprising: a) a liquid nitrogen fertilizer solution; and b) a quaternary-amine-comprising compound within the liquid nitrogen fertilizer solution.

  • Method of use of a coating compound in vessels, and a coating compound for vessels
    Patent number: 5702768
    Abstract: The invention encompasses methods of preventing corrosion of vessel sidewalls. In one aspect, the invention includes an anti-corrosion treatment method of reducing internal corrosion of an ammonium phosphate holding vessel comprising providing at least one quaternary-amine-comprising compound within the vessel. In another aspect, the invention includes a treatment method of reducing corrosion of a vessel sidewall surface comprising utilization of a quaternary amine to form a protective layer on the vessel sidewall surface. In another aspect, the invention includes an anti-corrosion treatment method of reducing corrosion of a vessel comprising: a) flowing a liquid into the vessel; b) adding at least one compound to the liquid, the compound being added to a concentration which exceeds the solubility of the compound in the liquid; and c) coating the compound onto an internal surface of the vessel to form a protective layer over the internal surface.
