Linde’s largest single-project facility in China has been put into operation. Author/Source: Gasification World. Date: 2021-07-29. Clicks: 27. Recently, Linde’s gas supply facility located in Qinzhou, Guangxi, was officially brought online, beginning to supply oxygen and other industrial gases to Shanghai Huayi Group’s integrated chemical materials production facility in Qinzhou (hereinafter referred to as the “Huayi Qinzhou Integrated Project”). The site is a joint venture established by Linde and Huayi Group, and it is also Linde’s largest single project in China, with a total investment of nearly 1.3 billion RMB. In addition to supplying gas to Guangxi Huayi Energy Chemical Co., Ltd., which operates the project, Linde has recently signed gas supply contracts with Guangxi Huayi New Materials Co., Ltd. and Guangxi Huayi Chlor-alkali Chemical Co., Ltd., both of which are part of the Shanghai Huayi Group. Since both companies are located in the Petrochemical Industrial Park within the Qinzhou Port Economic and Technological Development Zone, Linde will utilize its cluster gas supply business model to meet the industrial gas needs of all these companies simultaneously. Compared to the gas supply model in which gas-using enterprises install their own facilities, Linde’s cluster gas supply business model offers significant advantages in terms of enhancing park safety, reducing energy consumption and emissions, as well as ensuring the stability and cost-effectiveness of gas supply. Furthermore, Linde’s cluster gas supply business model also helps to improve the business environment and sustainability of chemical parks. The implementation of this gas supply model in chemical industrial parks provides a stable supply of industrial gases for the entire park, which helps to optimize the allocation of public resources, enhance the quality of supporting services, and achieve long-term industrial and social benefits ； Furthermore, the centralized construction and operation of air separation units can also effectively reduce the overall energy consumption of the park, enhancing its sustainability and contributing to the achievement of zero-carbon goals. Project Overview: The Huayi Qinzhou Chemical New Materials Integrated Base project is located in the Qinzhou Petrochemical Industrial Park. It covers an area of approximately 8,000 mu, with a total investment of around 70 billion yuan, and will be implemented in three phases. It covers four major industrial chains: coal chemical industry, light hydrocarbon cracking, salt chemical industry, and downstream petrochemical industry, involving 40 types of chemical products and 65 sets of facilities. Regarding one of the industrial gas island projects, the total investment amounts to 14.3 billion yuan; it is part of the coal chemical industry chain. Construction began in November 2017, with the aim of producing industrial gases such as hydrogen, syngas, and nitrogen for use by enterprises within the park, as well as chemical products like methanol, ethylene glycol, and acetic acid. Completion and operation are expected by 2020. The second-phase light hydrocarbon comprehensive utilization project has a total investment of around 20.8 billion yuan. It focuses on ethane cracking and propane dehydrogenation as its core processes, and is intended to produce products such as polyethylene, ethylene glycol, ethylene-vinyl acetate copolymer (EVA), acrylates, polyether polyols, caustic soda, and polyvinyl chloride. Construction is expected to begin in 2019. The main plant area of the project is located in plots 25 and 26 in the Qinzhou Petrochemical Industry Park, to the south of it. The third-phase methanol-to-olefins and downstream processing project has a total investment of around 18.3 billion yuan; it will produce products such as polypropylene, polycarbonate, polymethyl methacrylate, caustic soda, and polyvinyl chloride, with construction set to begin in 2025.
