最大超临界二氧化碳管道工程启动

Core Viewpoint - The Jilin Petrochemical-Jilin Oilfield CO2 pipeline project is a significant step in China's efforts to implement carbon reduction strategies and promote clean energy transition, with a focus on carbon capture, utilization, and storage (CCUS) [1][2] Group 1: Project Overview - The CO2 pipeline project, initiated on April 27, is the longest, largest diameter, and highest pressure CO2 pipeline in China, spanning nearly 400 kilometers [1] - The first phase of the project includes a pipeline length of 282.26 kilometers and a designed transport capacity of 3.3 million tons per year [1] - The pipeline will utilize supercritical/dense phase transport and will connect various cities in Jilin Province, facilitating carbon source absorption from local enterprises [1] Group 2: Technological and Operational Aspects - Advanced technologies such as centrifugal CO2 compressors and fiber-optic leak detection will be employed in the pipeline's design [1] - The project aims to enhance oil extraction efficiency by over 20% compared to traditional water-based methods, with an annual oil recovery of over 1 million tons [1] - The project emphasizes strict adherence to technical standards, material inspections, and the use of digital and intelligent monitoring methods to ensure quality and safety [2] Group 3: Strategic Importance - The project is aligned with China's national "dual carbon" strategy and is expected to be operational by 2026, serving as a backbone for carbon emission and utilization enterprises in Jilin Province [2] - It aims to promote the green and low-carbon transformation of enterprises in the region and further advance the development of the CO2 capture, utilization, and storage industry in China [2]
