Recently, Dazhou Jiuyuan New Materials Co., Ltd. plans to build a new materials production facility using urea and methanol as raw materials, with an annual production capacity of 500,000 tons of ethylene carbonate and 120,000 tons of lithium bisfluorosulfonylimide. Among them, vinyl carbonate can be used as a solvent for the electrolyte, while lithium bis(fluorosulfonylimide) is an important electrolyte material. At the 2023 Investment Promotion Event for Well-known Domestic and Foreign Enterprises in Sichuan and the Ceremony for Signing Project Cooperation Agreements, Jiuyuan Chemical (Group) signed a new materials project agreement with Dazhou. It is reported that the first phase of the new materials project involves the construction of a facility with an annual production capacity of 100,000 tons of ethylene carbonate, along with related supporting facilities, including upgrades to the ammonia synthesis plant ; Phase 1 of Phase 2 will involve the construction of a facility capable of producing 400,000 tons per year of ethylene carbonate along with related facilities, while Phase 2 of Phase 2 will see the construction of a facility capable of producing 20,000 tons per year of lithium bisfluorosulfonylimide along with related facilities ; Phase 3 construction of a 100,000 tons/year lithium bisfluorosulfonylimide production facility along with supporting facilities. Phase 1 of the project is scheduled to go into operation in 2026. Once fully built and put into operation, it is expected to generate an annual output value of 15 billion yuan and annual tax revenues of over 900 million yuan. It is reported that the energy-saving and carbon-reduction renovation project for synthetic ammonia was officially launched on January 6, 2025. All sub-projects of the renovation work are expected to be completed by February 2027. On November 30 of last year, Hong Kong Jiuyuan Chemical (Group) signed an agreement with Dazhou to build new material production facilities in the Dazhou High-Tech Zone in three phases. The investment planned for this project is 10 billion yuan, intended to enable the production of 500,000 tons of ethylene carbonate and 120,000 tons of lithium bisfluorosulfonylimide per year. This is Jiu Yuan Chemical (Group)’s capital increase project in Dazhou. In 2010, taking advantage of the abundant natural gas sulfur resources in Dazhou, Jiuyuan Chemical (Group) built and put into operation a facility in the Dazhou High-Tech Zone capable of producing 400,000 tons of synthetic ammonia and 450,000 tons of urea per year.

Dazhou is rich in natural gas and sulfur. It is located between Chongqing and Chengdu, and transportation there is quite inconvenient. I’m not sure if high-speed trains are available there now
CNPC had been drilling in Dazhou for many years, but after a tragic accident, it withdrew from the area.
They still exist today: CNPC and Sinopec
