Based on the characteristics of the compound fertilizer production device, Luxi Chemical Group has recently mastered the technology of dephosphorization of phosphoric acid and improved the utilization of resources and energy through technological innovation and equipment transformation.
It is understood that in the production of phosphoric acid, about 5% of fluorine is discharged through exhaust gas, and about 15% of fluorine is taken away by the waste slag phosphogypsum, and about 80% of fluorine is dissolved in phosphoric acid. The development of the downstream products of fluorine has become a technical problem that compound fertilizer manufacturers urgently need to overcome. After careful research, Luxi Chemicals has mastered the development of new technologies for the downstream products of sodium fluorosilicate, reducing the emission of fluoride and achieving the goal of clean and environmentally friendly production.
At the same time, due to the optimization of the production process conditions, the industrial chain is extended, and the dephosphorized phosphoric acid solution no longer contains fluorine, so that the final product compound fertilizer is completely defluorinated to form a fluorine-free compound fertilizer. After many tests, the compound fertilizer after defluorination eliminates the harm of fluorine to crops, improves the absorption of nitrogen, phosphorus, potassium and other nutrients by crops, and also protects the soil from being contaminated by fluorine.
Today, after the defluoridation, the Luxi compound fertilizer has successfully passed the “environmental eco-fertilizer†certification and achieved a sustainable development of the recycling economy. The sodium fluorosilicate produced by Luxi Chemicals, as an important chemical product, has been successfully launched into the market and has achieved good economic benefits.
