    Abstract: Methods are described for preventing corrosion in a corrosion-aggressive media. The methods include combining a stannous corrosion inhibitor composition with a corrosion-aggressive media (such as a nitrogen-based solution, or more specifically a liquid solution of AN or UAN) to provide a treated solution. The stannous corrosion inhibitor composition may include a caustic. Also described is a liquid including from 0.1 wt % to 25 wt % of a stannous salt and from 1 wt % to 50 wt % of a caustic, and a liquid composition including a solution of urea ammonium nitrate and a stannous material. The liquid and stannous corrosion inhibitor compositions substantially prevent corrosion of a metal surface even when used in very small amounts and at a low pH.

  • Patent number: 9856178
    Abstract: The invention is directed to manufacturing fertilizers having commercial levels of nitrogen reacted with organic substances. The process comprises treatment of organics with acid that acidifies and heats a mix causing the hydrolysis of polymers. The acidified organic mix is injected sequentially with a nitrogen base under conditions that result in a partially neutralized melt. The sterilized and liquefied organic matter is disbursed over recycled material for production of granules in a granulator before final drying. The process is green scalable, and safe for the location of community organics processing facilities in locations without generating a nuisance to local communities. Fertilizers also provide a green, dual nitrogen-release profile when applied to crops releasing a bolus of nitrogen over one to two weeks following application followed by a continued slow or enhanced efficiency release of nitrogen over a growing season.

The microcapsules, which may be applied to soil, seeds and/or plants, each have a shell that encapsulates an agricultural chemical, such as a fertilizer, herbicide or insecticide. One or more organosilane-coated magnetic nanoparticles is/are covalently bound into the shell of each microcapsule. For example, (3-aminopropyl)trimethylsilane-coated magnetite nanoparticles may be incorporated into the shell of a urea-formaldehyde (UF) microcapsule during in situ polymerization. In one embodiment, microcapsules encapsulating a fertilizer are applied during seed planting. Controlled release is subsequently triggered after an appropriate period of dormancy by positioning a magnetic field generating device proximate the microcapsules to generate a magnetic field sufficient to rupture the microcapsule shells through magnetic stimulation of the organosilane-coated magnetic nanoparticles.

  • Patent number: 8647406
    Abstract: Multiple-component fertilizer materials and methods of use are provided, wherein the fertilizer materials include first and second fertilizer products respectively including an ammoniacal fertilizer (e.g., urea) in combination with a partial calcium salt of a selected copolymer, and a phosphorous fertilizer (e.g., DAP) in combination with a partial sodium salt of a selected copolymer. The copolymer fractions of the first and second fertilizer products are most preferably copolymers of itaconic acid and maleic anhydride. The fertilizer materials give synergistically enhanced crop yields when applied to soil or growing plants.

  • Patent number: 8628598
    Abstract: An agricultural fertigation method includes the continuous in situ manufacture of one or more fertilizers within the irrigation system upstream of the agricultural field being irrigated. Co-reactant raw materials, namely sulfuric acid, phosphoric acid, nitric acid, potassium hydroxide, urea, ammonium hydroxide, ammonia, calcium nitrate and/or magnesium nitrate, are intermixed with each other and with the stream of the flowing irrigation water. The stream of flowing irrigation water dampens the resultant dissolution and reaction exotherms. A system wherein raw materials are efficiently continuously fed to the irrigation system main line or a side-arm reactor efficiently implements the method.

  • Patent number: 8617284
    Abstract: A macronutrient sustained release composition for a plant locus having nitrogen containing macronutrient compound adsorbed on the surface of hydroxyapatite phosphate nanoparticles, and a process for preparation thereof. The macronutrient adsorbed hydroxyapatite phosphate nanoparticles are encapsulated within cavities present in wood such that the biodegradation of the wood releases the adsorbed macronutrient compounds in a slow and sustained manner to the soil. Further, the macronutrient particles are encapsulated within the cell cavities of wood and wood is coated with cellulose modified hydroxyapatite phosphate nanoparticles such that the rupture of the nanocoating initiates the nitrogen release followed by the biodegradation of the wood releases the rest of the adsorbed macronutrient compounds in a slow and sustained manner to the soil.

  • Patent number: 8557013
    Abstract: The invention is directed to processes for treating biosolids that result in high-value, nitrogen-containing, slow-release, organically-augmented inorganic fertilizer that are competitive with less valuable or more costly conventional commercially manufactured fertilizers. The process involves conditioning traditional waste-water biosolids and processing the conditioned biosolids continuously in a high throughput manufacturing facility. The exothermic design and closed loop control of the primary reaction vessel decreases significantly the amount of power necessary to run a manufacturing facility. The process utilizes green technologies to facilitate decreased waste and enhanced air quality standards over traditional processing plants. The fertilizer produced from recovered biosolid waste is safe and meets or exceeds the United States Environment Protection Agency (USEPA) Class A and Exceptional Quality standards and is not subject to restrictions or regulations.
