With an Investment of RMB 41.6 Billion, the Phase II Expansion of Sinopec Zhenhai Refinery Was Completed, and the Annual Refining Capacity of Ningbo Petrochemical Base Exceeded 50 Million Tons

The Phase II expansion and new materials project of Sinopec Zhenhai Refinery was successfully completed, and the refining capacity was increased to 40 million tons per year, which also made the total refining capacity of the Zhejiang Ningbo Petrochemical Base exceed 50 million tons per year, further consolidating its position as the largest, most advanced and most internationally competitive petrochemical industrial base in China.

Located in the Yangtze River Delta, the Ningbo Industrial Base plays a vital role in Sinopec's value chain. The Phase II expansion project invested RMB 41.6 billion (approximately US$5.7 billion) and integrated 18 new production units, including key facilities such as atmospheric distillation, catalytic cracking, polypropylene and propane dehydrogenation. The project established a diversified high-value-added supply chain by prioritizing the development of chemical-focused processes.

The expanded capacity will support the production of high-end polyolefins, advanced materials and specialty chemicals to meet the growing demand of industries such as automobiles, home appliances and textiles. It is expected to produce 8 million tons of petrochemical products per year, creating huge economic value for the entire region.

Zhenhai Refining and Chemical is the flagship refining and chemical integration enterprise of Sinopec, with an ethylene production capacity of 2.2 million tons/year. It is the only Chinese company that has continuously ranked at the top in Solomon's global ethylene performance assessment.

The project is remarkable for its technological progress and commitment to sustainable development. Major achievements include the localization of 10 core technologies, demonstrating China's growing technological strength in the petrochemical field, such as the development of the world's highest-load vertical labyrinth compressor.

The extensive application of intelligent technology enables the digital factory and the physical factory to operate synchronously, optimize production processes and improve efficiency. In addition, the integration of a fully localized industrial operating system and an independently developed industrial Internet platform makes decision-making data-based and management more perfect. Finally, comprehensive energy-saving measures have reduced overall energy consumption by 11.7%, in line with environmental sustainability goals.

Throughout the construction process, safety and quality have always been the top priority, with continuous safety working hours exceeding 90 million hours and a 100% quality pass rate for all units.

The successful completion of this project demonstrates Sinopec’s commitment to innovation, technological advancement and sustainable development in China’s petrochemical industry. It positions China to become a global leader in this critical sector, driving economic growth and meeting the changing needs of a modernizing nation.
