Environmental impact assessment approved for Sinochem Wuhuan Xiangyun Phosphorus-Fluorine New Materials Project (re-submitted for approval)

Thread Content

On December 26, the Huanggang City Ecology and Environment Bureau approved the environmental impact assessment report for the Zhonghua Chemical Wuhuan Xiangyun Phosphorus-Fluorine New Materials (Hubei) Co., Ltd. project – a re-submitted application. The site for this project is located in the Makou Chemical Industry Park, which is part of the circular economy pilot zone for the development of a \"two-type\" society in Tianjia Town, Wuxue City. The construction is to be approved again and carried out in two phases. Phase 1 of the construction includes 2×15,000 tons per year of anhydrous hydrogen fluoride production units (including 2×7,500 tons per year of units for the comprehensive utilization of fluorosilicate slag), 10,000 tons per year of electronic-grade hydrofluoric acid production units, and 2,000 tons per year of ultra-high molecular weight phosphorus polymer production units. Phase 2 includes 2×15,000 tons per year of anhydrous hydrogen fluoride production units (with an additional 2×7,500 tons per year of units for the comprehensive utilization of fluorosilicate slag), 10,000 tons per year of electronic-grade hydrofluoric acid, 10,000 tons per year of lithium bis(fluorosulfonylimide), 6,000 tons per year of electronic-grade ammonium fluoride, 50,000 tons per year of potassium fluoride, and 30,000 tons per year of ultra-high molecular weight phosphorus polymers. Project background: The total planned investment for this project is approximately 3.93 billion yuan. In June 2023, it received approval from the Huanggang City Ecology and Environment Bureau, which authorized the construction of a facility capable of producing 50,000 tons per year of ultra-high molecular weight phosphorus polymers, 2 facilities capable of producing 30,000 tons per year each of anhydrous hydrogen fluoride, 2 facilities capable of producing 10,000 tons per year each of electronic-grade hydrofluoric acid, a facility capable of producing 6,000 tons per year of electronic-grade ammonium fluoride, a facility capable of producing 10,000 tons per year of lithium bis(fluorosulfonylimide), and (1+4) facilities capable of producing potassium fluoride per year. The project is constructed in two phases; Phase 1 includes a 20,000-ton/year ultra-high molecular weight phosphorus polymer plant, a 30,000-ton/year anhydrous hydrogen fluoride plant, a 10,000-ton/year electronic-grade hydrofluoric acid plant, a 10,000-ton/year lithium bis(fluorosulfonylimide) plant, and a 10,000-ton/year potassium fluoride plant. Phase 2 includes a 30,000-ton/year ultra-high molecular weight phosphorus polymer plant, a 30,000-ton/year anhydrous hydrogen fluoride plant, a 10,000-ton/year electronic-grade hydrofluoric acid plant, a 0.6000-ton/year electronic-grade ammonium fluoride plant, and a 40,000-ton/year potassium fluoride plant.
