The phosphate production unit of Wuhuan Company’s Xinxiangyun project completed its initial trial run successfully. Recently, good news came from the Sinochem Xinxiangyun New Materials Industrial Park in WuXue City, Hubei Province: the core units of this new phosphorus-based materials project, which were constructed under the general contract of China National Chemical Engineering Corporation’s Wuhuan Company, namely the medium-grade flame retardants and potassium dihydrogen phosphate production units (collectively referred to as the phosphate production units), successfully completed their initial trial run, marking steady progress toward the full operation of the project. 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 stepwise use of wet-process phosphoric acid and maximizing the added value of the products. Upon completion and operation of the project, it is expected to 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, offering 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 star-rated standardized construction sites for engineering projects, further optimize the project commissioning plan, and accumulate experience in startup and operational phases, thereby injecting new momentum into the high-quality development of China’s chemical engineering industry.
