摘　　要：氢气被广泛认为是清洁能源的未来之星,混氢天然气(HCNG)输送“潮流”已经席卷多国,它为解决氢气的运输问题提供了良好的解决方案,但由于氢气和天然气物理化学性质的差异,使得掺氢对现役天然气管道输送产生了一定的影响。为此,分析了6种典型天然气气源掺氢对天然气管道输送介质物性参数的影响,并基于TGNET软件计算分析了掺氢对管道输送能力的影响。结果表明:当掺氢体积比0~40%时,6种典型气源与不掺氢天然气相比,高热值、相对密度、沃泊指数分别下降了27%~30%、35%~36%和9.5%~11.0%;随着掺氢体积比的增加,管道输气能力下降约15%。研究成果为现役天然气管道输送HCNG的可行性研究提供了基础数据。Hydrogen is widely regarded as the future star of clean energy,and the"trend"of mixed hydrogen natural gas(HCNG)transportation has swept across many countries.It provides a good solution for solving the transportation problem of hydrogen.However,due to the differences in the physical and chemical properties of hydrogen and natural gas,hydrogen blending has a certain impact on the current natural gas pipeline transportation.In this article,the impact of hydrogen addition to six typical natural gas sources on the physical parameters of natural gas pipeline transportation media was analyzed,and the impact of hydrogen addition on pipeline transportation capacity were calculated and analyzed based on TGNET software.The results showed that when the hydrogen doping volume ratio was 0~40%,the high calorific value,relative density,and Wobbe index of the six typical gas sources decreased by 27%~30%,35%~36%,and 9.5%~11.0%,respectively,compared to natural gas without hydrogen;in addition,with the increase of hydrogen doping volume ratio,the gas transmission capacity of the pipeline decreased by about 15%.The research results provide basic data for the feasibility study of transporting HCNG through active natural gas pipelines.
