As the absolute leader in China’s refining and chemical industry, Sinopec boasts an annual crude oil processing capacity of over 300 million tons, occupying more than 30% of the domestic refining market share. Supported by 26 subsidiary refineries, Sinopec has built a nationwide and tiered industrial layout, forming a solid foundation for China’s energy supply and petrochemical manufacturing.
Among its extensive industrial layout, three core refineries — Zhenhai Refining, Maoming Petrochemical and Jinling Petrochemical — stand firmly in the first tier of Sinopec’s refining segment. With comprehensive advantages in production scale, profitability, technological innovation, industrial chain layout and strategic value, they serve respectively as a world-class refining benchmark, a South China industrial leader, and a model of differentiated transformation in East China. Together, they underpin the core competitiveness of Sinopec’s refining and chemical business.
Located in Ningbo, Zhejiang Province, Zhenhai Refining & Chemical originated from Zhejiang Refinery established in 1975. It is the largest, most technologically advanced and most efficient integrated refining and chemical enterprise under Sinopec, as well as China’s first 40-million-ton-level refining base. Widely regarded as the ultimate form of China’s refining industry, it ranks among the top-tier global refining benchmarks.
As of 2026, Zhenhai Refining holds a 40 million tons/year crude oil processing capacity, a 2.5 million tons/year ethylene capacity, and a 2 million tons/year aromatic hydrocarbon capacity, accounting for 13% of Sinopec’s total crude oil processing volume. It is the largest single-site integrated refining and chemical base in China.
Benefiting from the geographical advantages of Ningbo deep-water port, the enterprise realizes efficient full-chain coordination covering crude oil incoming, plant processing and product delivery, with a comprehensive raw material utilization rate exceeding 95%. It has completely broken the traditional refinery pattern of prioritizing oil products over chemical production, and built a full-value conversion system ranging from crude oil and refined products to chemical raw materials and high-end new materials.
Founded in 1955 and located in Maoming, Guangdong Province, Maoming Petrochemical is the first domestically built ten-million-ton-level refinery and the first million-ton-level ethylene plant in New China. After 70 years of development, it has grown into Sinopec’s core flagship enterprise in South China and one of the largest and most well-established state-owned refining and chemical enterprises in China.
Maoming Petrochemical possesses an 18 million tons/year crude oil processing capacity and a 1 million tons/year ethylene capacity. It is equipped with a 300,000-ton single-point mooring offshore crude oil unloading system and a complete port and pipeline transportation network. As a core supplier of refined oil products, chemical raw materials and military oil products for South and Southwest China, its oil supply covers Guangdong, Guangxi, Yunnan, Guizhou and other provinces.
Its high-quality chemical raw materials support the huge light industry and new material industrial clusters in the Pearl River Delta. As a core chain leader in South China’s energy and chemical industry, it plays an irreplaceable role in regional energy security and industrial development.
Situated in Nanjing, Jiangsu Province, Jinling Petrochemical traces back to a key national project of the Second Five-Year Plan launched in 1958 and was officially established in 1982. Ranking as Sinopec’s third-largest crude oil processing base, it serves as the most critical energy supply hub and fine chemical leader along the Yangtze River in East China, and a typical model of high-quality transformation for traditional mature refining enterprises through differentiated industrial layout.
Jinling Petrochemical has a comprehensive crude oil processing capacity of 18 million tons per year. Relying on the golden waterway of the Yangtze River, it has built an integrated logistics system combining terminals, railways, highways and pipelines, becoming a core supplier of refined oil and chemical raw materials in East China and riverine regions.
Its gasoline and diesel products occupy over 40% of Jiangsu’s market share, while its aviation kerosene supplies major airports across the Yangtze River Delta. It acts as a stable backbone guaranteeing regional energy security in East China.
As the core profit pillars and high-quality development benchmarks of Sinopec’s refining business, Zhenhai Refining, Maoming Petrochemical and Jinling Petrochemical represent the highest level of China’s modern refining and chemical industry. Their respective positioning in scale benchmarking, regional energy guarantee and differentiated transformation leads the overall upgrading and high-quality development of China’s petrochemical sector.
