  • Patent number: 10947166
    Abstract: The present disclosure concerns a method for producing fertilizer particles comprising an alternative source of boron. It is found that certain colemanite and ulexite powders can be supplied to a fertilizer melt shortly before granulation essentially without dissolving into the melt. Accordingly, the fertilizer particles produced from the melt may contain negligible amounts or non-detectable levels of sodium borates or boric acid. Furthermore, the fertilizer particles can be homogeneous which is desirable for boron supplying fertilizers. It is also found that the fertilizer particles can supply boron to plants at a rate comparable to borax pentahydrate.

  • Patent number: 10919815
    Abstract: To produce fertilizer, a system and method concentrates manure slurry in a mechanical vapor recompression evaporator (“MVR”) having a heat exchanger. The MVR receives the manure slurry within a first side to evaporate ammonia laden-water vapor from the slurry, leaving a nutrient concentrate. A compressor raises the evaporated ammonia-laden water vapor to a higher energy state. Within a second side of the heat exchanger, the compressed water vapor conveys heat to the slurry. Ammonia-laden water condenses in the second side at a process temperature to be conveyed to an ammonia stripping tower where the ammonia-laden water is dispersed into ammonia-laden water droplets. In the tower, a flow of air is directed across a surface of the ammonia-laden water droplets, the process temperature having been selected to promote the escape of ammonia gas from the ammonia-laden water droplets, the flow of air provided to entrain ammonia gas in the flow.

  • Patent number: 10870609
    Abstract: The invention relates to a coated granular fertilizer, preferably wherein granules are sulfate-based or phosphate-based. When sulfate based granules, as in ammonium sulfate, the coating substance is an inorganic salt of alkaline earth elements, preferably calcium, such that when applied to the surface of fertilizers, forms calcium sulfate, preferably a calcium sulfate-dihydrate, as a protective coating. For a reactive coating of a thiosulfate, free sulfuric acid present on the granule reacts to provide an elemental sulfur coating. For ammonium phosphate-based granules, coatings may comprise compounds of Ca++, Al+++ and/or Fe+++ salts thereby forming a calcium, an aluminum, an iron, or mixed cation phosphate protective coating. Thiosulfate is also effective with phosphate based granules which are manufactured with sulfuric acid.
