On January 7, 2025, the Wuyi Branch of Jinhua Municipal Ecology and Environment Bureau accepted the environmental impact assessment documents for Zhejiang Sanmei Chemical Co., Ltd.’s project to produce 90,000 tons per year of epichlorohydrin, 10,000 tons per year of tetrafluoropropene (HFO-1234yf), and 20,000 tons per year of polyvinylidene fluoride, and made these documents public. Project investment: 1.57 billion yuan. Upon completion of the project, new production capacities will be established for products such as 87,000 t/a of epichlorohydrin, 3,000 t/a of chiral epichlorohydrin, 7,300 t/a of glycerol monostearate, 10,000 t/a of tetrafluoropropylene, 10,000 t/a of polyvinylidene fluoride (emulsion method), 10,000 t/a of polyvinylidene fluoride (suspension method), and 4,043 t/a of difluorochloroethane. The project will be constructed in three phases: Phase 1 will see the construction of facilities for producing 50,000 tons per year of ECH and 30,000 tons per year of LNG; Phase 2 will involve the production of 10,000 tons per year of HFO-1234yf and 20,000 tons per year of PVDF; Phase 3 will focus on the production of 40,000 tons per year of ECH and 100,000 tons per year of glycerol. The project uses the glycerol method to produce ECH, employing glycerol instead of propylene for its production, which meets the requirements of environmental protection and sustainable development. As a fourth-generation refrigerant, HFO-1234yf holds broad application prospects. Undertaking this project will help seize development opportunities and strengthen the advantages in the refrigerant business. The demand for PVDF in downstream applications is strong; constructing this project helps to take advantage of scale effects, reduce production costs, and enhance the competitiveness of the products.
