中国石油西南油气田公司天然气研究院(以下简称天研院)主导编写的《天然气-甲烷值计算》国际技术报告,由国际标准化组织在瑞士日内瓦正式发布。这是我国在天然气标准化领域主导编写的首份国际技术报告。作为评价车用天然气抗爆性的一项重要指标,天然气甲烷值的计算以往一直缺乏统一的国际评价标准。天研院作为召集人,担纲编写《天然气-甲烷值计算》国际技术报告,多个国家的代表参与了编写工作。项目组对全球不同地区天然气进行采样计算和差异性分析,得出结论:对于绝大部分天然气而言,欧、美两种甲烷值计算法产生的差异不影响车用天然气抗爆性评价。当计算差
The International Technical Report on “Natural Gas - Methane Value Calculation” led by the Research Institute of Natural Gas of PetroChina Southwest Oil and Gas Field Company (hereinafter referred to as Tian Yan Yuan) was officially released by the International Organization for Standardization in Geneva, Switzerland. This is the first international technical report prepared by our country in the field of natural gas standardization. As an important indicator to evaluate the antiknock of natural gas vehicles, the calculation of natural gas methane has been the lack of a unified international evaluation standards. As a convener, Tianjingyuan took the compilation of an international technical report entitled “Calculation of Natural Gas - Methane Value”. Representatives of many countries participated in the compilation. The project team sampled and analyzed natural gas in different regions of the world and concluded that for most natural gas, the difference between the two methane values calculated in Europe and the United States does not affect the evaluation of antiknock capability of automotive natural gas. When calculating poor
