摘要
天然气计量与天然气物性参数的测定密切相关。国际标准化组织ISO/TC1 93/SC2从 1 995年开始进行以仪器仪表直接测定天然气物性参数的标准化工作 ,包括压力、温度、密度、压缩因子、发热量等九项与天然气计量相关的物性参数 ,并已形成工作草案。我国近几年也逐步开始对天然气水露点、水含量、发热量等物性参数直接测定方法进行研究和标准化。文章扼要介绍了这些方法的原理、应用范围、测定仪器和条件。
Measurement of natural gas physics property parameters has a direct bearing upon natural gas metering. The standardization of direct measurement methods of physics properties with apparatus has been developed since 1995,which involves nine physics parameters such as gas metering such as pressure, temperature, density, compressibility factor and heating value ect.related with natural gas metering by International Standardization Organization ISO/SC2. And at present committee drafts have been completed. In our country,the direct measurement methods of natural gas physics properties such as water dewpoint,water contents and eating value have come to be studied and standardized step by step. The principles, application ranges, apparatus, conditions, procedures and the precision of these measurement methods are discussed, and some proposals on the standardization of direct measurement methods of natural gas physics property parameters with apparatus launched comprehensively in our natural gas industry are put forward in the paper.
