China National Offshore Oil Corporation (CNOOC) and Shell have jointly launched the "dual projects" in Huizhou! The investment amount exceeds 57 billion yuan

On the morning of January 15, 2025, China National Offshore Oil Corporation (CNOOC) and Shell Petrochemicals Co., Ltd. announced that the final investment decisions for the Huizhou Phase III ethylene project and polycarbonate project have been completed, and comprehensive construction has officially begun. The total investment of the two projects is nearly 60 billion yuan, marking the deepening layout of CNOOC and Shell in the high-end new materials field entering the implementation stage.

The total investment of CNOOC Shell Huizhou Phase III Ethylene Project is about 48 billion yuan, with the construction of 1.6 million tons/year of ethylene and 16 sets of downstream chemical plants, as well as public works and supporting facilities. After the completion of the project, the ethylene production capacity of CNOOC Shell will reach 3.8 million tons per year, and it will continue to maintain its position as the largest single ethylene plant and the largest ethylene production base in China. The construction of the carbon aggregation project includes 260000 tons/year of carbon aggregation equipment, 240000 tons/year of bisphenol A and 220000 tons/year of diphenyl carbonate equipment, as well as supporting research and development facilities. It can produce 320000 tons of high-performance specialty chemicals annually, which is of great significance to the transportation, construction, medical and consumer goods fields.

Huizhou Phase III Ethylene Project

The CNOOC Shell Huizhou Phase III Ethylene Project will construct a 1.6 million ton/year ethylene cracking unit and 16 downstream chemical production units and supporting facilities, with a total investment of approximately 48 billion yuan. It is planned to be completed and put into operation in 2028.

After the completion of the project, the ethylene production capacity of CNOOC and Shell will reach 3.8 million tons per year, continuing to maintain the "crown" of the largest ethylene monomer plant in China, with significant economies of scale. This project will also be optimized and integrated with existing chemical and refining projects in the first and second phases, further improving the integration of refining and chemical processes and enhancing resource utilization efficiency.

From the start of the first phase of the project in 2002, to the official production of the second phase in 2018, and now that the final investment decisions for the third phase of the ethylene project and the carbon polymerization project have been made, the world-class petrochemical giant of CNOOC and Shell has been deeply rooted in Daya Bay, Huizhou for 24 years, continuously growing and writing good stories. With a total investment of over 100 billion yuan in Huizhou, it has added momentum to the construction of a global petrochemical industry highland and the creation of a new growth pole for high-quality development in Guangdong.

In addition, the project introduces multiple process technologies that have been applied for the first time in Asia and China. Among them, 7 sets of equipment adopt Shell's proprietary technology, which can provide chemical products such as metallocene polyethylene, polypropylene, styrene, etc. to the market every year, achieving an overall 20% reduction in carbon dioxide emissions and promoting the utilization of renewable green energy electricity.

Polycarbonate project

The polycarbonate project will construct 260000 tons/year polycarbonate plant, 240000 tons/year bisphenol A plant, 220000 tons/year diphenyl carbonate plant, as well as supporting research and development facilities. It is planned to be completed by the end of 2026. After the project is completed and put into operation, it can produce 320000 tons of high-performance specialty chemicals such as polycarbonate and carbonate solvents annually, which can be applied in transportation, construction, medical and consumer goods fields, meeting the market demand for differentiated new products.

Looking back at the development history of CNOOC and Shell in Daya Bay, Huizhou, from the start of the first phase project in 2002 to the official production of the second phase project in 2018, and now after the final investment decisions for the third phase ethylene project and polycarbonate project, they have successively entered the stage of comprehensive construction. CNOOC and Shell, this world-class petrochemical "giant", have been deeply rooted in Daya Bay, Huizhou for 24 years.

During this period, CNOOC and Shell continued to grow and expand, with a total investment of over 100 billion yuan in Huizhou, injecting strong momentum into the construction of a global petrochemical industry highland and the creation of a new growth pole for high-quality development in Guangdong.
