Zhejiang Petrochemical Co., Ltd. was established on June 18, 2015, as a mixed-ownership enterprise with private capital as the majority shareholder and state-owned capital as a minority shareholder. The 40-million-ton-per-year integrated refining and petrochemical project (hereinafter referred to as “the Project”), invested in and constructed by the company, is located within the Zhoushan Green Petrochemical Base in Zhejiang Province. It serves as a key pillar for the China (Zhejiang) Pilot Free Trade Zone in building a complete oil products industrial chain and implementing the “Three Bases and One Center” development strategy. The Project covers a total planned area of 41 square kilometers with a total investment of 173 billion yuan. It produces more than 20 types of petrochemical products, including National VI-compliant gasoline and diesel, jet fuel, paraxylene (PX), high-end polyolefins, and polycarbonates.

Our company was awarded the contract for this project in March 2021, adopting a cooperative model involving the supply of process packages, proprietary equipment, and proprietary catalysts. The project’s feed gas is derived from CO₂ emissions from an ethylene glycol unit. By adopting our new process—a combination of catalytic oxidation and shallow-cold distillation—the project ensures product quality compliance with the “GB 1886.228-2016 National Food Safety Standard for Food Additive Carbon Dioxide.”

The project achieved full-scale production in June 2024 and has been operating stably since then.
