Sinopec Starts Construction of Million-Ton Low-Concentration CCUS Project at Shengli Oilfield
- The project targets completion and startup by the end of 2028.
- Flue gas contains 12%–15% CO₂; the process is designed for a capture rate above 90% and product purity above 99.5%.
- Heat consumption is expected to be below 2 GJ per tonne of captured CO₂.
- The capture unit will receive green power through an integrated wind, storage and direct-connection system.
Project and technology
Construction has started on China’s first million-ton-scale full-chain CCUS demonstration project for low-concentration emissions at Shengli Oilfield. It will capture CO₂ from coal-fired power plant flue gas for oilfield flooding and storage. The gas contains 12%–15% CO₂ and impurities including sulfur and nitrogen oxides. Sinopec says its self-developed absorbents and energy-saving regeneration process are designed to achieve a capture rate above 90%, product purity above 99.5% and heat consumption below 2 GJ per tonne of CO₂.
Schedule and earlier project
The project is expected to be completed and start operation by the end of 2028. Captured CO₂ will be injected into reservoirs, including beach-bar sand, turbidite and shale formations. The site will use an integrated wind power, energy storage and direct-connection system to supply green electricity to the capture unit.
The Qilu Petrochemical–Shengli Oilfield million-ton CCUS project, which began operation in August 2022, captures high-concentration tail gas from a coal-to-hydrogen unit. It has stored 1.4 billion standard cubic metres of CO₂, while crude oil recovery in the demonstration area has increased by more than 15%.
