On September 3, the technical upgrade project for Zhejiang Zhongning Silicon Industry Co., Ltd. to increase production capacity by 100 t/a of fluorine-nitrogen mixture and 5 t/a of propylsilane was approved for registration. Project Name: Technical renovation project for adding 100 t/a of fluorine-nitrogen mixture and 5 t/a of propylsilane filling capacity ； Construction unit: Zhejiang Zhongning Silicon Industry Co., Ltd ； Construction location: Zhizao New City, Quzhou City, Zhejiang Province ； Proposed start date: February 2026 ； Planned completion date: July 2026 ； Project content and scale: This project involves technical upgrades to the existing production facilities, which were previously approved for 100 t/a of fluorine-nitrogen mixture and 20 t/a of ethylsilane filling. New electrolyzers, fluorine coolers, purifiers, adsorption towers for fluoride-containing exhaust gases, gas distribution tanks, compressors, etc., will be purchased. An additional production line for 100 t/a of fluorine-nitrogen mixture will be set up, along with a capacity for 5 t/a of propylsilane filling. Upon completion, the project will enable annual production of 200 t/a of fluorine-nitrogen mixture, 20 t/a of ethylsilane, and 5 t/a of propylsilane.
