摘要
通过管道输送超临界CO2是大规模运输CO2最经济、可行的方法,国内目前仅有少量短程气态CO2输送管道,尚无超临界CO2长输管道。介绍了国外超临界CO2管道的发展现状,迄今尚无针对性的管道设计、运行参考标准及管输超临界CO2的质量控制标准。分析了超临界CO2管道腐蚀、橡胶溶胀、泄漏、断裂等影响超临界CO2管道运行安全的因素及控制经验,可为中国未来超临界CO2管道的设计与运行提供参考。国内建设超临界CO2输送管道必然经过人口密集区域,运行风险增大,应予以重视。
Supercritical CO2 transportation by pipeline is the most economical and feasible method to transport large-scale CO2. There are already some short distance gaseous CO2 pipelines in China, but not long distance supercritical CO2 pipelines yet. The paper introduces the status quo of supercritical CO2 pipelines overseas, and there are no design and operation reference standards and CO2 quality control standards yet. The risk and security issues related to pipeline transmission, such as corrosion, elastomeric seals, leakage and running fracture of supercritical COs pipeline are analyzed. The aim of this paper is to draw upon the design, operating and risk control experiences gained from the existing CO2 pipeline networks to provide references to the design and operation of supercritical CO2 pipeline in China. Special attention should be paid on safety since the supercritical CO2 pipeline will inevitably pass through densely populated areas in China. （3 Tables, 15 References）
