摘要:

氢气是一种零排放的二次能源,是实现“双碳”目标的重要能源之一。采用在役天然气管道或管网输送掺氢天然气,是实现氢气大规模输送的有效方式。精确控制进入输送系统的掺氢比例对系统安全运行具有重要意义。本文介绍了电气式和机械式随动掺氢系统的结构与原理;分析了红外吸收型、热传导型、半导体型浓度传感器和相应的综合测量系统在掺氢比动态调整中的应用;重点评述了目前3个重要在役天然气掺氢示范项目中随动掺氢系统的组成和运行结果;基于工程实践经验展望了天然气掺氢技术的发展趋势。

Abstract:

Hydrogen is a secondary energy with zero emission, one of the most important energy sources to achieve the goal of “double carbon”. Using in-service natural gas pipeline or network to transport hydrogen blended to natural gas is an effective way to realize large scale transport of hydrogen. It is important to accurately control the proportion of hydrogen in the natural gas pipelines transport system. The structure and principle of electric type and mechanical type with following up hydrogen blended to natural gas system are introduced. The concentration sensors of mechanism and application with infrared absorption type, heat conduction type, semiconductor type are introduced. Then, their comprehensive measurement system in dynamic adjustment and measurement of hydrogen blended to natural gas ratio are analyzed. Three important in-service hydrogen blended to natural gas demonstration projects are introduced from the composition and operation results. Based on the engineering practice experience, the development trend of hydrogen blending to natural gas technology is projected.

Key words: hydrogen blended to natural gas, hydrogen mixing principle, gas-gas mixing structure, dynamic measurement of hydrogen mixing ratio
