Recently, the wastewater treatment facility for the new utility systems at CNOOC Shell Huizhou polycarbonate project reached a key milestone: the core A/O biological treatment tank has successfully seen the completion of its main structure, marking significant progress in the project’s development and advancing steadily toward the goal of completion by the end of 2026! As a key flagship project in Huizhou Daya Bay Petrochemical Zone, this project has a total investment of 9.3 billion yuan, with the main focus on building three production facilities: one for producing bisphenol A at a capacity of 240,000 tons per year, one for diphenyl carbonate at 220,000 tons per year, and one for polycarbonate at 260,000 tons per year. Looking back at the project timeline, the environmental impact assessment documents were made public in April 2024, and construction officially commenced on February 28, 2025. The completion of the core wastewater treatment equipment marks a new phase in the construction of the project’s utility facilities, laying a solid foundation for the installation of the main equipment that will follow. The project boasts numerous highlights, leading in both technology and value! ✅ World’s first innovative technology: Utilizes Shell’s proprietary production technology, which is used on an industrial scale for the first time; it features low raw material costs, low energy consumption, and excellent safety and environmental properties ； ✅ Filling the high-end gap: Upon production, it will be able to produce 320,000 tons per year of high-performance specialty chemicals (including polycarbonates and carbonate solvents), which are widely used in industries such as transportation, construction, healthcare, and consumer goods, thus meeting the market’s demand for high-quality chemical products ； ✅ Facilitating industrial upgrading: By staying true to the vision of a \"world-class integrated petrochemical hub,\" it helps China’s petrochemical industry move up to the higher end of the global value chain.
