The third phase of CNOOC Shell's ethylene project and polycarbonate project in Huizhou has started full-scale construction!
Recently, CNOOC Shell Petrochemical Co., Ltd. has completed the final investment decision for its third phase ethylene project and polycarbonate project in Huizhou, officially kicking off full-scale construction.

The third phase of the CNOOC Shell ethylene project will build a 1.6 million tons/year ethylene cracking unit and 16 sets of downstream chemical production facilities and supporting facilities. It is planned to be completed and put into operation in 2028. This project introduces multiple process technologies that are being applied for the first time in Asia and domestically. Among them, seven sets of facilities adopt Shell's proprietary technology and can provide over 5 million tons of chemical products to the market annually, including metallocene polyethylene, polypropylene, styrene, polyether polyols, ethylene glycol, α -olefins, synthetic alcohols, and polyα -olefins. Meanwhile, through measures such as optimizing the project scope and electrifying large compressor units, the third-phase project will achieve an overall 20% reduction in carbon dioxide emissions and promote the utilization of renewable green energy power.
The polycarbonate project will build A 260,000-ton/year polycarbonate plant, a 240,000-ton/year bisphenol A plant, a 220,000-ton/year diphenyl carbonate plant, as well as supporting research and development facilities. It is planned to be completed by the end of 2026. This project will adopt Shell's proprietary production technology, which is being industrialized for the first time globally. It features low raw material and public utility costs, low energy consumption, and is safe and environmentally friendly. After the project is completed and put into operation, it can produce 320,000 tons of high-performance specialty chemicals annually, including polycarbonate and carbonate solvents.
Gao Yu, the president of CNOOC Shell, said, "The new project will be integrated with the existing resources of the first and second phases and the refining industry of Huizhou Petrochemical, enhancing the energy efficiency of the integrated refining and chemical industry, effectively extending the product value chain, deepening the layout in the high-end new materials field, and meeting the domestic customers' demands for the extension and development of the petrochemical industry chain." At the same time, it will help CNOOC Shell further leverage the "banyan tree effect" and the driving advantages of major projects, attracting more downstream customers to settle in the Huidong New Materials Industrial Park near Huizhou Dayawan, and making new contributions to the construction of a global petrochemical industry highland in Huizhou and Dayawan.

Cnooc Shell Petrochemical Co., Ltd. was established in 2000. Currently, two phase plants are in operation, with a total ethylene production capacity of 2.2 million tons per year. It is one of the largest ethylene monomer petrochemical integrated plants in operation in China. After the completion of the two new projects, CNOOC Shell's total ethylene production capacity will reach 3.8 million tons per year, and it will be able to supply over 10 million tons of high-quality and diversified petrochemical products to the market.
Huang Zhongjin, vice president of CNOOC Shell, said, "These two projects will help CNOOC Shell achieve its strategic goal of becoming the preferred partner for highly differentiated product solutions." With the continuous investment in product application research and development and the sustained improvement of its R&D capabilities, CNOOC Shell will provide customer-centered product solutions, develop and produce customized and high-end products, and fulfill its commitment to sustainable development and a high-quality lifestyle. At the same time, the completion of the final investment decisions for the two new projects fully demonstrates the confidence of both shareholders in the future development of CNOOC Shell, its favorable government and enterprise ecosystem, and the growth in demand for high-performance chemical products in China.
