Huizhou Daya Bay Petrochemical Industrial Park planning a total area 27.8km2. Since 2001, development and construction, petrochemical area to 12 million tons refinery and CNOOC CSPC 950,000 tons of ethylene as the basis, attracted participants from the United States, Japan, the Netherlands, more than 20 countries and regions in the international oil and chemical companies stationed. As of February 2013, a total of 75 projects have been settled, with a total investment amounting to 159.9 billion RMB.

       Huizhou Daya Bay Petrochemical Industrial Zone as a leader in large-scale integrated refining, petrochemical downstream industries extension of the development of major petrochemical industrial cluster has begun to take shape, the industry has laid a good foundation conditions for the future development of the park. According to CNOOC's refinery industry long-term planning, Huizhou Daya Bay Petrochemical Zone will be a large-scale integrated refining base its development focus of the layout, in the future will form a 42 million tons / year oil refining, 5 million tons / year of ethylene and 300 million tons / year aromatics scale industry. Construction of large-scale integrated refining base of CNOOC, will be leading the future to achieve leapfrog development leading Huizhou Daya Bay petrochemical area, it will also provide a rich supply of raw materials and stable development of the park downstream petrochemical industry. Through the industrial chain extension of the park, you can improve the comprehensive utilization of the product, the value chain to achieve growth, the further processing of petrochemical-based raw materials into high-performance composite materials, specialty chemicals, high-end value-added products to meet the Pearl River Delta region as well as domestic high-end petrochemical products rapidly growing market demand.
