Latest Patents

Thrasher holds a patent for a process titled "Recovery of phosphates from elemental phosphorus bearing wastes." This patent describes a method for oxidizing aqueous elemental phosphorus containing residues to produce orthophosphate containing slurries. These slurries are suitable for subsequent reactions with ammonia to create nitrogen- and phosphorus-containing fertilizer products. The process involves reacting aqueous elemental phosphorus residues with specific mixtures of concentrated nitric acid and sulfuric acid. This reaction converts the elemental phosphorus into mostly orthophosphoric acid, with minimal production of orthophosphorous acid. The relative ratios of these acids depend on the weight ratio of sulfuric acid to nitric acid used in the process. The reaction is conducted at the boiling point of the resulting aqueous medium. Prior to conversion into fertilizer products, the aqueous reaction product may undergo a solids separation step to eliminate insoluble salts of environmentally harmful metals such as lead, cadmium, barium, and chromium.
