en.Wedoany.com Reported - Wedoany News, May 12 — The polyether unit of the HPPO project at Guangxi Chlor-Alkali Company, part of the Huayi Qinzhou Chemical New Materials Integrated Base, has successfully produced qualified products, achieving a successful startup on the first attempt. This unit is the first to be commissioned and put into operation within the HPPO project. Its successful startup marks the project's official transition from the engineering construction phase to the trial production phase, laying the foundation for the smooth startup of subsequent units.
The successful startup of the polyether unit not only achieved smooth commissioning and stable operation of the facility but also accelerated the practical growth of a professional technical team.
The Huayi Qinzhou Chemical New Materials Integrated Base, invested and constructed by Shanghai Huayi Holding Group Co., Ltd., is a significant outcome of deepening east-west cooperation between Guangxi and Shanghai, and also a major industrial project for Guangxi to undertake industrial transfer from the eastern region. The base is planned to cover an area of 8 square kilometers, with a total investment exceeding 90 billion yuan, and is being advanced in three phases. Currently, the total investment of 16.2 billion yuan for Phase I and its supporting projects has been fully completed, the total investment of 18.9 billion yuan for Phase II and its supporting projects is largely finished, and preliminary work for Phase III projects is being accelerated.
Among them, the Phase III project has a planned investment of approximately 55 billion yuan. Led by methanol-to-olefins technology, it primarily involves the construction of projects for bisphenol A epoxy resin, specialty epoxy and organosilicon new materials, PBAT biodegradable materials, polyurethane industry support and waste salt recycling, methanol-to-olefins and downstream deep processing integration, and hydrogen peroxide to propylene oxide (HPPO) and polyether polyol integration. This drives the diversification and differentiation of downstream olefin products. The polyether unit that has now been put into operation is an important component of the Phase III HPPO project.
The Phase I project was an industrial gas island project, mainly building a coal chemical industry chain to produce industrial gases such as hydrogen, syngas, and nitrogen, along with products like methanol, ethylene glycol, and acetic acid. The Phase II project is a 750,000-ton/year propylene and downstream deep processing integration project, encompassing units for acrylic acid and esters, butanol, propane dehydrogenation, phenol/acetone, and bisphenol A.
The successful startup of this polyether unit has pressed the accelerator button for the full-line commissioning of the HPPO project and further consolidated the Huayi Qinzhou Base's production capacity layout in the field of new chemical materials.
