Latest Patents

Grinstead holds a patent for "Phosphatic and nitrogen fertilizers via HNO.sub.3 processing." This patent describes a process for producing high-analysis dicalcium phosphate containing phosphatic fertilizers and by-product calcium nitrate. The method involves reacting phosphate rock with nitric acid, followed by pyrolysis of the resulting acidulate. This process liberates approximately one-half of the initially consumed nitric acid, allowing for recycling and reducing the overall acid consumption during production. The resulting fertilizers have a high available phosphate content of 48% P.sub.2 O.sub.5, making them suitable for various applications.
