Announcement on Linde Gas’ air separation project with an annual production capacity of 630,000 tons of oxygen, 440,000 tons of nitrogen, and 25,000 tons of argon – On March 30, an announcement was made regarding the approval of Linde Gas (Jiaxing) Co., Ltd.’s air separation project with such annual production capacities. The project is located in Nanhu High-Tech Zone, Jiaxing City, Zhejiang Province, bordered by Jinglan Environmental Protection to the east, Ziyu Road to the south, Bujiao Road to the west, and open land to the north. The total planned investment for the project is 452.88 million yuan. The scheduled start date is April 2026, with completion expected by May 2027. The project plans to lease the factory buildings and associated facilities located at the northeast plot at the intersection of Jiagang Road and Bujiao Road in the Nanhu High-Tech Zone of Jiaxing, owned by Jiaxing Dongyun Nickel-Chromium New Materials Co., Ltd. The project will involve the investment in constructing an air separation unit, supporting liquid gas production facilities, a system for the production and storage of medical oxygen, a system for the production and storage of food-grade liquid nitrogen, as well as a pressurized pipeline system for delivering high-purity nitrogen to electronic and chemical industry users in nearby industrial parks. Additionally, corresponding backup systems will be built, including large storage tanks for liquid oxygen, liquid nitrogen, and liquid argon; on-site storage tanks capable of supplying high-pressure oxygen, nitrogen, and argon; loading, unloading, weighing, and metering stations for liquid oxygen, nitrogen, and argon tankers. There will also be supporting auxiliary facilities such as an 110KV substation, a circulating water station, and a fire pump room. Meanwhile, during the construction of this project, an existing nitrogen liquefaction unit that is currently in operation at Linde Gas (Jiaxing) Co., Ltd.’s facility will also be relocated to the site of this project. The project is planned to produce 590,000 tons of oxygen per year, 260,000 tons of nitrogen, 40,000 tons of medical-grade high-purity liquid oxygen, 180,000 tons in total of food-grade and electronic-grade high-purity liquid nitrogen, and 25,000 tons of electronic-grade high-purity liquid argon. The overall plan for this project involves construction in phases, as detailed below: Phase 1 of the project: the temporary storage of liquid oxygen and the pumping and gasification system will be built and put into operation. It supplies gas to Dongfang Special Steel until the air separation unit is built and starts operating stably, and then it is used as an operational storage tank. Phase 2 of the project: The main air separation process unit, as well as the backup systems and the associated utility services and auxiliary facilities, are completed and put into operation. Phase 3 of the project: The existing nitrogen liquefaction unit that is in operation at Linde Gas (Jiaxing) Co., Ltd. will be relocated to the site of this project, where it will be integrated with the main air separation process units ； A nitrogen pressurization unit and external pipeline network are used to supply nitrogen to local industrial parks via pipelines.
