On May 12, 2026, the polyether unit of the HPPO project of Guangxi Chlor Alkali Company in Huayi Qinzhou Chemical New Material Integration Base successfully produced qualified products, achieving the goal of meeting the standard in one start-up. As the first device to be put into production and operation in the HPPO project, this successful commissioning means that the project has officially transitioned from the construction phase to the trial production phase. It not only lays a solid foundation for the smooth operation of subsequent devices, but also opens the curtain for the full production of the project.

The successful start-up of the polyether device not only achieved smooth production and stable operation of the device, but also exercised team style and improved professional ability, enabling a backbone team that dares to fight hard and can win battles to grow and mature rapidly. This is the fruitful result achieved by all employees of the company working together, fighting hand in hand, and solving problems. This project is invested and constructed by Shanghai Huayi Holdings Group Co., Ltd. It is not only an important achievement of deepening cooperation between the eastern and western regions of Guangxi and Shanghai, but also the largest industrial project undertaken by Guangxi to transfer industries from the east.

Project Planning

The project covers an area of 8 square kilometers with a total investment of over 90 billion yuan, and will be gradually constructed in three phases. At present, the investment of 16.2 billion yuan for the first phase and supporting projects has been fully completed, the investment of 18.9 billion yuan for the second phase and supporting projects has been basically implemented, and the preliminary preparation work for the third phase project is being accelerated.

The contract was signed in July 2017, and the first phase of the project officially started in November of the same year; In March 2019, the second phase project was signed and implemented; In June 2021, the first phase of the project was completed and put into operation, becoming the first major industrial project worth billions of yuan to be put into operation during the 14th Five Year Plan period in Guangxi; In November 2021, the lifting of the propylene propane separation tower for the Phase II project was successfully completed, marking the full entry of the Phase II project into the process equipment installation phase; From December 2022 to March 2023, each device of the Phase II project will be put into operation successively; In 2023, the third phase of the project will commence construction, and the first sub project, a 20000 ton/year polymerization inhibitor project, will start construction on May 9th.

Specific content of each phase of the project

Phase I project: It is an industrial gas island project with a total investment of approximately 16.2 billion yuan, focusing on the construction of the coal chemical industry chain. It can produce industrial gases such as hydrogen, synthesis gas, nitrogen, etc. for use by various users in the park, and also produce chemical products such as methanol, ethylene glycol, and acetic acid.

Phase II project: It is a 750000 tons/year integrated project for propylene and downstream deep processing, with a total investment of 18.9 billion yuan. It mainly constructs multiple sets of facilities, including 400000 tons/year acrylic acid and ester, 300000 tons/year butanol, 750000 tons/year propane dehydrogenation, etc., which can produce various chemical products such as polyethylene, ethylene glycol, EVA, etc. Keywords: Huayi Qinzhou, HPPO project, polyether plant

Phase III project: The planned total investment is about 55 billion yuan, with methanol to olefin as the core, focusing on the construction of multiple projects such as polymerization inhibitors, bisphenol A epoxy resin, special epoxy, and organic silicon new materials, focusing on the high-end new materials field, and promoting the diversified and differentiated development of downstream olefin products.Editor/Gong Ziwei
