[SMM Express] On August 28, the Dazhou Ecological Environment Bureau accepted and publicized the high-purity anhydrous hydrogen fluoride project of Wengfu Dazhou Chemical Co., Ltd. Wengfu (Group) Co., Ltd. possesses world-leading patented technology for co-producing anhydrous hydrogen fluoride through the wet process phosphoric acid method, with seven existing anhydrous hydrogen fluoride units already achieving an annual capacity of 220,000 mt.
Project construction scope and scale: Leveraging the by-product fluorosilicic acid from the company's existing wet process phosphoric acid technology, the project will establish production facilities for 30,000 mt/year of high-purity anhydrous hydrogen fluoride and 20,000 mt/year of high-purity hydrogen fluoride, along with storage tanks and supporting utility infrastructure (Phase I), to achieve comprehensive utilization of fluorine resources associated with phosphate ore.
