Hubei Wengfu Haiyu Fluorosilicon Technology Co., Ltd.’s 20,000 tons per year high-purity anhydrous hydrogen fluoride and 20,000 tons per year high-purity hydrofluoric acid production projects

Thread Content

On January 7, the first public announcement regarding the environmental impact assessment for Hubei Wengfu Haiyu Fluorosilicon Technology Co., Ltd.’s project to produce 20,000 tons per year of high-purity anhydrous hydrogen fluoride and 20,000 tons per year of high-purity hydrofluoric acid was made. The details of the project are as follows: Project name: 20,000 tons per year of high-purity anhydrous hydrogen fluoride and 20,000 tons per year of high-purity hydrofluoric acid project； Construction unit: Hubei Wengfu Haiyu Fluorosilicon Technology Co., Ltd ； Construction location: Chemical Industry Park, Hujи Economic Development Zone, Hujи Town, Zhongxiang City, Jingmen City ； Project nature: New construction ； Construction contents: Using fluorosilicic acid produced as a by-product of wet phosphoric acid as raw material, facilities for producing 20,000 tons per year of high-purity anhydrous hydrogen fluoride and 20,000 tons per year of high-purity hydrofluoric acid will be built, along with supporting facilities such as raw material storage tanks, product storage tanks, cooling stations, air compression stations, circulating water systems, substation, and a comprehensive control building. Further reading: On August 7, 2025, the signing ceremony for the Hubei Wengfu Haiyu anhydrous hydrogen fluoride project was held at Jiumen Jiupaitongyuan. This project is jointly developed by Wengfu Group and Dayukou Company, which is part of China National Offshore Oil Corporation, with a total investment of around 410 million yuan. By combining the resource and operational advantages of Dayukou Company with technological strengths such as Wengfu Group’s globally pioneering method of producing anhydrous hydrogen fluoride from fluorosilicic acid, this project enables the sustainable utilization of hazardous waste from the phosphate chemical industry (fluorosilicic acid generated as a by-product of wet-process phosphoric acid production). It can help fill the gap in high-end fluorine material production capacity in Central China, thereby facilitating the domestic production of key materials for the semiconductor and new energy industries. Building on the first phase of the project, future developments will focus on expanding the production of high-value products such as fluorine-based fine chemicals (intermediates for pharmaceuticals and pesticides), fluorinated polymer materials, and electronic specialty gases (nitrogen trifluoride). Regarding Hubei Wengfu Haiyu Fluorosilicon Technology Co., Ltd.: Hubei Wengfu Haiyu Fluorosilicon Technology Co., Ltd. was established on September 30, 2025, with a registered capital of 150 million yuan. It was founded jointly by Wengfu (Group) Co., Ltd. and Hubei Dayukou Chemical Co., Ltd., with Wengfu Group holding a controlling stake. The company is mainly engaged in the production and sales of fluorine, iodine, silicon, and related chemical products, as well as in the import and export of technologies and goods. Located in the Chemical Industry Park of Hujи Economic Development Zone, Zhongxiang City, Jingmen City, Hubei Province, it covers an area of 200 mu. Leveraging the abundant by-product fluorosilicic acid resources in Dayukou, Hubei, and combining it with Wengfu Group’s technical expertise in converting fluorosilicic acid into anhydrous hydrogen fluoride, the company is committed to transforming the fluorosilicic acid generated during phosphate fertilizer production into high-value-added products such as anhydrous hydrogen fluoride and electronic-grade hydrofluoric acid.
