我国运输距离最长规模最大的二氧化碳管道开建

Core Insights - The Jilin Petrochemical - Jilin Oilfield CO2 Pipeline Project has officially commenced, marking a significant step in China's carbon capture and storage efforts [1] - The pipeline, spanning approximately 400 kilometers, is the longest, largest diameter, and highest pressure CO2 pipeline in China, with an expected annual underground CO2 storage capacity exceeding 4 million tons [1] - The project aims to create a carbon network in Jilin Province, facilitating the transition of local enterprises towards green and low-carbon development [1] Group 1 - The CO2 pipeline project is a key initiative responding to national policies and the strategic deployment of China National Petroleum Corporation [1] - The pipeline will utilize advanced technologies such as supercritical/mixed-phase CO2 transport, centrifugal compressors for boosting pressure, and fiber-optic leak detection, addressing existing technological gaps in the country [1] - The project will connect multiple cities and counties, allowing for the absorption of carbon sources from enterprises like Jilin Petrochemical [1] Group 2 - Jilin Oilfield has achieved a dual effect of "oil recovery" and "carbon fixation" through CO2 capture, utilization, and storage (CCUS) technology [2] - In 2024, the oilfield plans to inject 41.8 million tons of CO2, accounting for 22% of the total CO2 injection by China National Petroleum Corporation [2] - The practical applications of CO2 include green methanol and carbon-rich agriculture, indicating the significant potential for CCUS technology to transition from industrial to commercial use [2]
