掺氢输送对长输天然气管网标准体系的影响研究

摘要：

【目的】探讨分析长输天然气管网掺氢后，对原有天然气管道标准体系的影响，并分析天然气管道标准体系的适用 性。【方法】采用文献分析法，基于我国天然气管道标准体系现状，分析了掺氢对天然气物理化学性质、输送特性、计量准 确性、材料兼容性及管道运行安全等多个方面的主要影响，进而对相应天然气管道标准体系和相关标准的技术内容提出了 完善建议。【结果】研究发现，天然气管道标准体系总体上适用于掺氢输送，但在重点领域需要开展专项研究，对相关标准 进行修订，并且制定专项标准。【结论】需要开展输氢管道标准体系建设，制定标准制修订计划，加快标准研究，以确保掺 氢天然气的安全、高效、经济输送。

Abstract:

[Objective] This study aims to investigate the impact of hydrogen blending on the existing standards system for  long-distance natural gas pipeline networks and assess the applicability of the standards system. [Methods] Through literature  review and analysis, the study evaluates the current state of China’s natural gas pipeline standards. It examines the effects of  hydrogen blending on the physical and chemical properties of natural gas, transmission characteristics, metering accuracy,  material compatibility, and pipeline operational safety. Based on these analyses, targeted suggestions are made to improve  and supplement the technical content of relevant standards. [Results] The existing standards system for natural gas pipelines  is generally applicable to hydrogen-blended transmission. However, key areas require specialized research and revisions to  ensure safe and effective implementation, including the development of new, dedicated standards. [Conclusion] Establishing  a dedicated hydrogen transmission standards system, along with a systematic plan for standard development and revision, is  essential to support the safe, effi cient, and economical transportation of hydrogen-natural gas mixtures.
