摘要:
According to a method of producing a phosphate fertilizer, a first portion of the phosphate is produced in a pipe cross reactor, and a second portion of the phosphate is produced in a pre-neutralizer. Both the first and second portions of the phosphate are supplied to a granulator. Ammonia is added to the granulator to react with the first and second portions of the phosphate. To produce the first portion of the phosphate, a micronutrient is added to phosphoric add to produce an enriched acid, and the enriched acid and ammonia are added to the pipe cross reactor where they are allowed to react to produce ammonium phosphate.

摘要:
A biological-laden dry fertilizer includes a dry fertilizer granule and a coating inoculated with a biological agent and applied to the dry fertilizer granule. The biological coating is a solution or suspension comprising water or oil and at least one biological agent, or an emulsion of an oil and a solution or suspension comprising water and at least one biological agent. The at least one biological agent is a biological chemical, plant extract, microbial agent, and/or a living organism.
摘要:
A method for conditioning fertilizer granules for improved dust control, agricultural benefits, or both, the method comprising: providing a plurality of fertilizer granules into a conditioning vessel, the fertilizer granules having a surface temperature of 10°C (50°F) to 121.111°C (250°F); introducing an aqueous conditioning agent comprising water to an outer surface of the plurality of fertilizer granules in the conditioning vessel in an amount of 0.1 wt% to 10 wt% of the total weight of the fertilizer granules, the aqueous conditioning agent being in the form of liquid, steam, or superheated steam; subjecting the plurality of fertilizer granules with the aqueous conditioning agent thereon to a mechanical energy exposure in the form of tumbling or mixing the plurality of fertilizer granules in the conditioning vessel to condition the outer surface of the fertilizer granules; and drying the plurality of fertilizer granules to remove moisture added from the aqueous conditioning agent until a final moisture content of the fertilizer granules is between 0 wt% to 6.5 wt% of the granules.

摘要:
Coatings and additives including a fatty acid or salt of fatty acid for application to granules. The coatings or additives can be applied to granules of, for example, fertilizer or animal feed. The fatty acid can be stearic acid, another saturated fatty acid, a salt of fatty acid such as sodium stearate, or combinations thereof, and can optionally include a carrier fluid. Preferably, the coating or flow additive is animal feed-grade certified to be used for products incorporated into food or animal feed as a nutrient supplement.
摘要:
A cooling pond system and related methods of improving cooling performance in a cooling pond system using one or more submerged dams to increase cooling performance within the cooling pond system, and increase salt precipitation or recovery. The inclusion of one or more submerged dams within an existing cooling pond system can reduce an outflow temperature by 1-5°F as compared to the same cooling pond system without any submerged dams. In addition or alternatively, pond depth can be controlled to enhance flow mixing and convection cooling. As the temperature is reduced throughout the cooling pond system, more potassium containing salts are precipitated from the brine solution resulting in increased production or recovery within the same cooling footprint.
