Thread Content

On November 10, the ion-exchange membrane caustic soda unit in Phase 4 of the Gansu Juhua High-Performance Silicofluorine New Materials Integration Project (hereinafter referred to as the Gansu Juhua Project) was fully completed, thus achieving an important construction milestone. This completion has provided valuable time for the subsequent installation of equipment and the construction of process pipelines, accelerating the overall progress of the project.

In addition, the structure of the fluoropolymer circulating water station for the Gansu Juhua project was also successfully completed. From the start of construction on July 28 until the completion of the structure, it took only 105 days to complete this project, setting a new record for the construction of circular water treatment plants of similar scale. The total design capacity of the project’s circulating water station is nearly 80,000 m³/h; of this, the fluoropolymer circulating water station has a capacity of 20,000 m³/h. It is equipped with an open-type mist eliminating cooling tower 22 meters high, with a single-story area of 1,600㎡.

On November 20, the Gansu Provincial Department of Ecology and Environment accepted the environmental impact assessment report for Gansu Juhua New Materials Co., Ltd.’s project aimed at improving the performance of fluorochlorine-based new materials, and made it public. The details of this project are as follows: Project name: Gansu Juhua New Materials Co., Ltd. High-Performance Fluorochlorine New Materials Integrated Improvement Project ; Construction unit: Gansu Juhua New Materials Co., Ltd ; Construction location: Chemical Industry Park, Old Town Area of Yumen Economic Development Zone ; Project nature: New construction ; Project investment: Total investment of 2,016,455,800 yuan ; Construction contents: (1) HFP facility: mainly two new reactors will be added, and the existing HFP equipment will be modified to increase the production capacity of hexafluoropropylene (HFP) by 21,000 tons per year ; After the project was implemented, the HFP production capacity of the entire plant reached 50,000 t/a. A new HFP section has been added for use in the H-yf unit, while the excess capacity (14,000 t/a) is used to produce products for sale. (2) H-yf units: 2 new units will be built to achieve an annual production capacity of 20,000 tons of 2,3,3,3-tetrafluoropropene (1234yf) ; This set of equipment uses a process route of hexafluoropropylene (HFP)–pentafluoropropane (R245eb)–2,3,3,3-tetrafluoropropene (1234yf). After the implementation of this project, the company will cease producing the third-generation refrigerant pentafluoropropane (R245eb) and will expand its industrial chain to develop the fourth-generation refrigerant 2,3,3,3-tetrafluoropropene (1234yf). (3) T-yf units: 2 additional units have been added, resulting in an annual production capacity of 15,000 tons of 2,3,3,3-tetrafluoropropene (1234yf) ; This set of equipment uses a process route involving carbon tetrachloride–tetrachloropropane–2,3,3,3-tetrafluoropropene (1234yf). The carbon tetrachloride raw material comes from the existing methane chloride plant. (4) Chloromethane plants: 3 new plants will be added, resulting in an annual production capacity of 100,000 tons of chloromethane, thereby filling the gap in the growing market for this substance. (5) According to market research, the Jiuquan region has a large sulfuric acid production capacity that can meet the enterprises’ demand for this substance; therefore, the enterprises plan to abandon the construction of sulfur-based sulfuric acid production facilities. After the implementation of this project, the sulfuric acid required by the enterprise will be obtained through external purchases. (6) As the design progresses and becomes more detailed, the company plans to optimize and adjust the capacity and processes of the hazardous waste incineration unit and the wastewater treatment plant outlined in the original environmental impact assessment, based on the amounts of wastewater generated by various facilities, as well as the exhaust gases and liquids containing high levels of fluorine and chlorine ; A new pretreatment unit for waste antimony-containing catalysts has been added to treat the waste catalysts (antimony pentachloride) from the existing R22 units, thereby reducing certain risk factors. Gansu Juhua New Materials Co., Ltd. was established on March 15, 2023, with its registered address in Yumen City, Jiuquan City, Gansu Province. It is a second-tier wholly-owned subsidiary of the Juhua Group. Juhua Group mainly produces fluorine chemicals and basic chemical raw materials. It has developed a chemical industry chain led by fluorine chemistry, with chlor-alkali chemistry and coal chemistry as its foundations, and advanced technologies in fine chemicals, synthetic materials, and technical services as key areas for innovation. The group offers more than 180 varieties of \"Juhua\" brand products across 17 categories, including those in the fields of chemicals for pharmaceutical use, chemical ores, non-ferrous metals, and building materials. It is a well-known manufacturer of fluorine chemicals and sulfonamide drugs in China. The company has a **-level enterprise technology center and an enterprise postdoctoral research station; it serves as the backing entity for the “**Fluorine Materials Engineering Technology Research Center” and the “Zhejiang Juhua Technology Cooperation Park”.
