Latest Patents

Peng Chen holds a patent for a method of production of ammonium phosphate from phosphate rock slurry. This method involves several steps, including the introduction of flue gas containing SO into a phosphate rock slurry to yield an absorption solution. The process continues with the evaporation of waste ammonia water, which contains 10-20 wt. % ammonia, to produce ammonia gas. This gas is then introduced into the absorption solution at a temperature of 110-135°C until the neutralization degree reaches 1.5-1.6, resulting in an ammonium phosphate solution and calcium sulfate. The calcium sulfate is separated from the ammonium phosphate solution, which is then granulated to yield ammonium phosphate granules. Finally, these granules are dried and sieved to produce the final product.
