2.2 million tons/year refined phosphoric acid, ammonium phosphate relocation and supporting equipment upgrading project -- Yihua Group Hubei Yihua Phosphorus Chemical Co., Ltd.

The project is located in Yaojiagang Chemical Park, Yichang, Hubei Province, with an altitude of 86-90m, average annual relative humidity of 78%, average atmospheric pressure of 0.1MPa,   temperature of 39.4℃ and temperature of -5.1℃. The raw materials of the project are phosphate rock and sulfur, and the final products include refined phosphoric acid, ammonium phosphate, compound fertilizer, high-grade flame retardants, and by-products of fluorosilicic acid. Through relocation and upgrading, the production of industrial grade refined phosphoric acid has been adjusted to 300,000 tons/year of diammonium phosphate, 300,000 tons/year of powdered monoammonium phosphate and 50,000 tons/year of industrial monoammonium phosphate. In this project, the flotation machine and mixing adopt the direct transmission mode of the reducer, and the delivery management is carried out according to the digital management process, which is the time for our factory to complete the digital management process, and has certain significance.
