Method of use of a coating compound for liquid-fertilizer holding vessels, and liquid fertilizers

An anti-corrosion treatment method of reducing internal corrosion of a liquid nitrogen fertilizer holding vessel comprising providing a quaternary-amine-comprising compound to a concentration of from about 50 ppm to about 400 ppm in liquid nitrogen fertilizer within the vessel.

A treatment method of improving clarity in a liquid-fertilizer product comprising providing at least one quaternary-amine-comprising

• compound within the liquid-fertilizer product.

A treatment method of reducing sludge formation in a liquid-fertilizer product comprising providing at least one quaternary-amine-comprising compound within the liquid-fertilizer product.

An anti-corrosion treatment method of reducing corrosion of a liquid nitrogen fertilizer holding vessel comprising:

• providing a substantially insoluble liquid film of a quaternary-amine-comprising compound over a volume of liquid nitrogen fertilizer within a steel vessel;
• and
• 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.

An anti-corrosion treatment method of reducing corrosion of a stationary liquid nitrogen fertilizer holding vessel comprising:

• providing a quaternary-amine-compound in a mixture with liquid-fertilizer solution in a mobile liquid-fertilizer transporting vessel the quaternary-amine-comprising compound comprising alkyl dimethyl benzyl ammonium chloride, the alkyl comprising at least 12 carbon atoms;
• and
• flowing the mixture from the mobile transporting vessel to the stationary vessel.

An 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, the quaternary-amine-comprising compound comprising alkyl dimethyl benzyl ammonium chloride, the alkyl comprising at least 12 carbon atoms.

An anti-corrosion mixture, comprising:

• a liquid solution comprising a nitrogen fertilizer, the nitrogen fertilizer consisting essentially of one or more fertilizers selected from the group consisting of ammonium nitrate, urea ammonium nitrate, ammonium sulfate, and calcium ammonium nitrate;
• and
• a quaternary-amine-comprising compound within the liquid solution, the quaternary-amine-comprising compound comprising alkyl dimethyl benzyl ammonium chloride.

An anti-corrosion mixture, comprising:

• a liquid-fertilizer solution;
• and
• at least one quaternary-amine-comprising compound combined with the liquid-fertilizer solution, the quaternary-amine-comprising compound being present to a concentration which exceeds the solubility of the quaternary-amine-comprising compound in the liquid-fertilizer solution, the quaternary-amine-comprising compound comprising alkyl dimethyl benzyl ammonium chloride.
