Core Viewpoint - China National Offshore Oil Corporation (CNOOC) has successfully implemented the country's first offshore membrane decarbonization demonstration project, achieving the recovery of over 20 million cubic meters of associated gas and efficient decarbonization, recovery, and resource utilization [1] Group 1: Project Overview - The Huizhou 32-5 platform is one of the high-yield oil platforms in the eastern South China Sea oil field, serving as a pilot for advancing green and low-carbon transformation [1] - The project has innovatively established a technical system for efficient carbon dioxide capture, reinjection, and storage [1] Group 2: Technical Process - The project process includes three main stages: raw gas pretreatment, membrane separation decarbonization, and post-membrane treatment and recovery [1] - The membrane separation decarbonization stage utilizes a self-developed membrane decarbonization device by CNOOC, which occupies less space and consumes less energy, making it highly suitable for offshore platform environments [1] Group 3: Innovation and Impact - In the post-membrane treatment and recovery phase, the project innovatively employs the same well injection and production technology, allowing for the compression and safe reinjection of carbon dioxide without affecting oil extraction [1] - This approach addresses the challenge of resource constraints in offshore platform well slots and provides a replicable and scalable new pathway for carbon storage in offshore oil fields [1]
