摘要:

在天然气分析测试领域, 我国已初步建立了与国际接轨的天然气分析检测系列技术。综述了天然气取样、组成分析、硫化合物含量分析、水/烃露点检测、固体颗粒物和其他有毒有害物质的检测、物性值计算以及标准物质制备等技术,并从实验室的能力验证和分析比对等方面提出了对检测结果的质量保证方式。随着我国天然气工业的迅猛发展以及天然气国际贸易的快速增长,对天然气分析检测技术提出了新的要求,展望了我国在天然气分析检测技术方面的发展方向。

Abstract:

In the field of analysis and measurement of natural gas, China has established a series of technologies acting on international convention. The article summarizes the detection technologies including sampling of natural gas, composition analysis, detection of sulfide content, determination of water/hydrocarbon dew point, solid particulate matter, other hazardous and noxious substances, property parameter calculation,and preparation of reference material. Quality assurance to analysis result was also put forward from the aspects of proficiency test in laboratory as well as analysis comparison. With rapid development of natural gas industry and increasing international trade of natural gas, new demand was raised in analyzing and measuring natural gas. The paper also outlooks the development direction of natural gas analysis and measurement technology.
