Public announcement regarding the re-submission for environmental impact assessment of the Zhonghua Chemical Wuhuan Xiangyun Phosphorus-Fluorine New Materials project after adjustments

Thread Content

Recently, the Huanggang Municipal Department of Ecology and Environment issued a notice regarding the re-submission for approval of the environmental impact assessment for the Zhonghua Chemical Wuhuan Xiangyun Phosphorus-Fluorine New Materials project. The details of the project are as follows: In order to further reduce pollutant emissions and improve the comprehensive utilization of resources, changes were made during the construction of this project; the scale of some facilities was adjusted, the sequence of construction was altered, certain production processes were changed, and the layout plans as well as the scale of auxiliary facilities also changed. As a result, it is necessary to resubmit the environmental impact assessment documents for this project. 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 Municipal 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(fluorosulfonyl)imide, and (1+4) facilities capable of producing 10,000 tons per year each of potassium fluoride. The project is constructed in two phases; Phase 1 includes a 20,000-ton/year facility for ultra-high molecular weight phosphorus polymers, a 30,000-ton/year facility for anhydrous hydrogen fluoride, a 10,000-ton/year facility for electronic-grade hydrofluoric acid, a 10,000-ton/year facility for lithium bis(fluorosulfonylimide), and a 10,000-ton/year facility for potassium fluoride. 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.
