摘要:: 近年来，CO₂捕集、利用与封存（Carbon Capture, Utilization and Storage，CCUS）因其直接降低碳排放而备受关注，作为CCUS的重要环节，CO₂管道输送技术也备注关注。为此，系统分析国内外CO₂输送管道规范的发展历史及现状，结合国内外相关CO₂输送管道规范，重点分析了CO₂输送管道设计中管道材料选择、CO₂脱水、阀室设置、管道放空、管道干燥封存等方面的要点和需要注意的问题，并提出了相关应用建议：管道内腐蚀控制主要手段建议为对CO₂气源进行充分脱水；管道路由选择应避免通过人口密集区的高地势侧，同时充分参考DNV-RP-F104-2021；管道泄漏研究急需开展相关试验，以获得更多数据支持，同时建议开展CFD数值分析，重点分析人口密集高后果区管道泄漏扩散影响并辅助确认管道阀室间距。研究成果可为中国CO₂输送管道的设计、建设及规范编制提供借鉴。

Abstract:: In the past decade, carbon capture, utilization and storage (CCUS) has attracted much attention because of its direct reduction of carbon emissions. As an important part of CCUS, pipeline transportation technology is also one of the dominant focus of various countries. This paper systematically analyzes the development history and current situation of carbon dioxide transmission pipeline specifications at home and abroad. Combined with relevant domestic and foreign carbon dioxide transmission pipeline codes, it focuses on the analysis of line pipe material selection, dewatering of the CO₂, valve station design, vent systems design, pipeline dewatering and drying and other key points in the design of carbon dioxide transmission pipelines. The problems that need attention are put forward, and some suggestions are put forward: the main method of corrosion control for pipeline is sufficient dewatering of the CO₂; pipeline route should be selected avoid passing through the high-terrain side of populated areas, and full reference shall be made to the provisions of DNV-RP-F104-2021 on valve station setting; it is urgent to carry out relevant tests for pipeline leakage research to obtain more data support, and it is recommended to carry out CFD numerical analysis, focusing on analyzing the impact of pipeline leakage diffusion in populated high-consequence areas and assisting in confirming the distance between pipeline valve stations. The research results can provide reference for the design, construction and specification preparation of CO₂ transport pipelines in China.
