| 摘 要： | 介绍了ISO/TR 22302:2014的主要内容,包括甲烷值的定义,美国气体研究院的两种甲烷值计算方法,给出了方法的限定范围,给出了36个欧洲、30个中国和泰国的天然气组成计算的甲烷值。讨论了同一天然气组成采用美国气体研究院两种方法计算甲烷值时,如果甲烷值之间的差值超过6个点,那么应该是该天然气的组成不符合计算方法的限定范围。ISO/TR 22302:2014为甲烷值的应用提供了有利的技术支持。

| Abstract: | This article introduced the main contents of ISO/TR 22302:2014, including the definition of methane number, two calculation methods of methane number developed by Gas Research Institute (GRI), listed the limitation of two methods and calculated the methane numbers of 36 gas mixtures from European and 30 gas mixtures from China and Thailand. It discussed that if the difference between two GRI methods is more than 6, the composition of natural gas should not be in accordance with the limitation of the calculation method. ISO/TR 22302:2014 gives the technical supports for application of methane number. |
