Thread Content

On July 2, the monitoring report on the environmental protection inspection following the completion of Phase 3 of Duofuduo New Materials Co., Ltd.’s project to produce 30,000 tons per year of ultra-pure lithium hexafluorophosphate crystals was made public. The project of Duofuduo New Materials Co., Ltd. to produce 30,000 tons per year of ultra-pure lithium hexafluorophosphate crystals is located within the company’s existing factory complex. It will be constructed in three phases, with each phase involving the renovation and expansion of the existing hydrofluoric acid production facilities in order to increase the HF production capacity by 8,428 tons per year ； A new lithium hexafluorophosphate production facility with an annual capacity of 10,000 tons will be built. In phases one and two, calcium chloride will be produced using the by-product hydrochloric acid; in phase three, hydrochloric acid will be used directly as a by-product. Additionally, various production equipment and environmental protection facilities will be installed as part of this project. During the construction of Phase 3, for market reasons, a production facility for lithium fluoride as a raw material was not built anymore, and lithium fluoride was purchased externally instead ； Second, the phosphorus pentachloride production facility is optimized, while the other construction elements remain unchanged. The actual construction includes 1 set of lithium hexafluorophosphate production facilities with a production capacity of 10,000 t/year, comprising a phosphorus pentafluoride facility, a lithium hexafluorophosphate synthesis facility, and other by-products. The scope of this inspection covers the Phase 3 project of Duofuduo New Materials Co., Ltd., which involves an annual production capacity of 30,000 tons of ultra-pure lithium hexafluorophosphate crystals. The inspection includes an assessment of the construction progress of Phase 3, as well as various environmental protection measures related to waste gas, wastewater, solid waste, and noise. The actual production capacity includes 10,000 tons per year of lithium hexafluorophosphate as the main product, along with other by-products.
