摘要
天然气气相色谱组成分析在天然气贸易中起着重要作用。论述了天然气组成分析准确度对计算的发热量和烃露点的影响,而天然气标准气体是保证天然气分析结果准确可靠的一种计量器具。我国天然气标准气体准确度等级与国际上相比存在较大差异。本文介绍了美国西南研究院研究项目"气相色谱用天然气校准气体制备方法"中制备标气的"最佳经验做法",并提出相关建议。
Natural gas analysis hy GCs play an important role in gas trade.This article describes the influence of natural gas accuracy hy GCs on the caloric value and hydro carbon dew point calculated front gas composition,and natural gas standards are a kind of measuring instrument to guarantee the accuracy of natural gas analysis results.There is a big difference in the accuracy class of natural gas standards in our country when compared with the international advanced levels.This article gives the 'best practices for gas preparation,proposed in the research project of 'Preparation method for chromatographic natural gas calibration standards' undertaken by Southwest Research Institute (USA). and put forward relative recommendations.
