** The birth of a food-grade phosphoric acid process

(Reporter Mi Ran) The reporter learned from Kane Deli (Beijing) Electronics Co., Ltd. yesterday that the 10,000-ton/year food-grade phosphoric acid project independently developed and designed by him was successfully tested in Egypt. The effective content of phosphoric acid products produced by this project is above 85%, and all the indicators have met or exceeded the technical requirements for food grade phosphoric acid. This is also the world's first large-scale food-grade phosphoric acid production facility.


According to the person in charge of the project, Kendrick (Beijing) Electronics Co., Ltd. independently researched and developed the ** food-grade phosphoric acid production process, and created and constructed a karst-phosphoric acid-calcium chloride recycling industrial chain in a breakthrough manner. . The use of ** instead of ** to produce phosphoric acid not only effectively avoids the production of phosphogypsum, reduces environmental pollution, but also allows low-grade phosphorite to be processed into feed-grade, industrial-grade and food-grade phosphoric acid in high yields; Phosphorus ore grade requirements have greatly increased the utilization of phosphate rock resources.


It is understood that the wet process phosphoric acid process that phosphate rock through decomposition of inorganic acids, first made with crude phosphoric acid fertilizer, and then purified impurities, and finally concentrated purity and thermal process of high-purity phosphoric acid products. At present, the wet-process phosphoric acid process uses ** to decompose phosphate ore to obtain phosphoric acid, and the separation of main product phosphoric acid and by-product **calcium is a simple liquid-solid separation. Because of its simple process route, the ** method has always played a leading role in the production of wet-process phosphoric acid, but its disadvantage is that the comprehensive utilization rate of large amounts of phosphogypsum produced is low, and the problem of “three wastes” is serious.

**Process Phosphoric Acid Production Process includes processes such as milling, melting, filtration, extraction, evaporation, and impurity removal. The phosphoric acid is extracted and purified through special processes to obtain food-grade phosphoric acid, and calcium chloride is produced by-product. Produce any contaminants. The process equipment is streamlined and the floor space is small.

At present, the sales market for ** is narrow and sluggish, and there are problems in both transportation and storage. The ** production process has found a way out for the byproduct ** in potassium production, and the byproduct calcium chloride can also increase project benefits. According to the person in charge of the company, they will continue to upgrade their technological level and produce medical grade phosphoric acid products.
