The Phosphorus Group Mineral Fertilizer Co., Ltd. has improved the concentrated phosphoric acid acidity rate by 5 percentage points through the technical reform, and calculated the annual production capacity to increase the company's annual revenue by more than RMB 12 million.
Concentrated phosphoric acid as an important raw material for the production of phosphorus compound fertilizer, should be a colorless, transparent or slightly yellowish thick liquid, but due to more suspended solids produced in the production of phosphoric acid, slower acidity tends to affect diammonium production. To this end, the company has specifically set up a project team to improve the acidity rate to protect the quality of diammonium production. On the basis of controlling the acid extraction reaction, the project team will improve the production process, perform a complete rectification of the original clarifier pipeline, reduce the amount of clarifier added, improve the concentrated acid pipeline in the concentrated acid tank area, and improve the acid clarification efficiency.
