Recently, good news came from the Zhonghua Chemical Xinxiangyun New Materials Industrial Park in Wuxue City, Hubei Province: the core units of the Xinxiangyun phosphorus-based new materials project, which were constructed under the general contract of China National Chemical Engineering Fifth Ring Company, namely the mid-range flame retardant and potassium dihydrogen phosphate production units (collectively referred to as the phosphate units), successfully completed their first-scale trial operation, pushing the project toward full-scale production at a steady pace. Phase I of the project covers an area of approximately 2,000 mu. Using phosphate rock, sulfur, and pyrite as raw materials, it produces bulk products such as compound fertilizers. At the same time, the phosphogypsum generated is utilized comprehensively, thereby enabling the hierarchical use of wet-process phosphoric acid and maximizing the added value of the products. Once the project is completed and put into operation, it will generate an output value of 10 billion yuan and create approximately 1,200 new jobs, bringing significant economic and social benefits. The phosphate plant utilizes the continuous phosphate crystallization technology independently developed by Wuhuan Company, offering significant advantages such as a short process flow, high degree of automation, excellent product consistency, and low energy consumption. Its crystallizer scrubber tower and crystallizer are designed as an integrated unit, featuring a compact structure ； Internal guide cylinders and agitators are installed to create a stable internal circulation slurry flow field, which not only ensures an optimal crystallization environment but also facilitates the growth of particle crystals, thereby enabling high-quality continuous crystallization production. Next, the project team will strictly comply with the requirements set by the group company for creating standardized construction sites for engineering projects, further optimize the project’s commissioning plan, and accumulate experience in operation and production, thereby injecting new momentum into the high-quality development of China’s chemical engineering industry.
