  • Publication number: 20230022971
    Abstract: The invention is directed to organic fertilizers having commercial levels of nitrogen reacted with organic substances. The scalable process comprises adding an organic processing center to a fertilizer granulation plant specifically for the treatment of organics with an acid that acidifies, heats and liquifies a mix resulting in the hydrolysis of most or all organic material and polymers. For ammonium sulfate-based fertilizer this mix is only reacted with concentrated sulfuric acid. For ammonium phosphate fertilizers, this mix is reacted with both concentrated sulfuric acid and a concentrated phosphoric acid. The acidified organic mixes are piped to an existing or new granulation plant where it is injected with anhydrous ammonia in a tee mixer/reactor that results in a partially neutralized melt. Subsequently a sterilized and liquefied organic melt is sprayed over recycled bed material for production of granules before drying.

  • Patent number: 10351436
    Abstract: Bromine containing compounds, such as calcium bromide, sodium bromide and the like, are prepared in high purity and more quickly with less waste by using a process with two bromination stages and often a third step wherein the crude product mixture can be adjusted to meet specific product requirements. In the first bromination stage, the majority, but not all, of a substrate is brominated using a reductive bromination reaction, the remaining unreacted substrate is converted to product in the second stage through another a reductive bromination reaction, although the specific reagents may be different, wherein the addition of bromine and a reducing agent are carefully monitored.
