Environmental Impact Assessment Approval for the Integrated Improvement Project of High-Performance Fluorochlorine New Materials at Gansu Juhua New Materials Co., Ltd

Thread Content

Recently, the Gansu Provincial Department of Ecology and Environment intends to issue its approval decision on the environmental impact assessment document for Gansu Juhua New Materials Co., Ltd.’s project aimed at improving the performance of fluorochlorine-based new materials. Project Link: Project Name – Gansu Juhua New Materials Co., Ltd. High-Performance Fluorochlorine New Materials Integrated Improvement Project; Location – Chemical Industry Park in the old area of Yumen Economic Development Zone; Constructor – Gansu Juhua New Materials Co., Ltd.; Project Investment – The total investment for this project is 2,016,455,800 yuan; Environmental Assessment Agency – Zhejiang Environmental Technology Co., Ltd.; Project Overview: (1) HFP Facility: Two new reactors will be added, and the existing HFP equipment will be modified, resulting in an increased production capacity of hexafluoropropylene (HFP) of 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 devices 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 new 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 processing 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 flue gases and liquid wastes 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 plants, thereby reducing certain risk factors.
