China Petroleum & Chemical Corporation's (Sinopec) recently announced the mechanical completion of the second-phase expansion and advanced materials project at its Zhenhai Refinery.

The refinery's capacity has now been upgraded to 40 million tons per year, contributing to the Zhejiang Ningbo Petrochemical Industrial Base surpassing a total refining capacity of 50 million tons annually. The achievement solidifies its position as China's largest, most advanced, and globally competitive petrochemical industrial base.

The second-phase expansion and advanced materials project, with a total investment of CNY 41.6 billion, incorporates 18 production units, including atmospheric distillation, catalytic cracking, polypropylene, and propane dehydrogenation units. By emphasizing chemical-focused processes, the project creates multiple high-value-added supply chains.

The facility's expanded production capacity supports the development of high-end polyolefins, advanced materials, and specialty chemicals. It is expected to provide approximately 8 million tons of petrochemical products annually.

This expansion is forecast to generate trillions of yuan in upstream and downstream industrial value.

Zhenhai Refinery, Sinopec's largest integrated refining and chemical enterprise, boasts an ethylene production capacity of 2.2 million tons per year. It is also the only enterprise in China consistently ranked in the top performance group of the Solomon Global Ethylene Performance Evaluation.

Located in the Yangtze River Delta, a key downstream product consumption hub, the Zhejiang Ningbo Petrochemical Industrial Base plays a vital role in Sinopec's value chain.
