摘要:
进入天然气长输管道气体质量要求》标准的制订和实施与GB 17820 《天然气》协调一致,将进一步规范进入天然气长输管道的气体质量。该标准规定发热量、总硫等指标有大幅度提升,将对天然气处理工艺、分析测试等多方面产生深远的影响,尤其是总硫含量跨数量级的提升将有效地契合国家和公众对环保的要求。而H2、CO等指标的确定也将有效扩大标准适用范围,确保对现阶段进入天然气长输管道气体种类的全覆盖。 

Abstract:
The national standard Quality Requirements for Gases Entering Long-distance Transportation Gas Pipeline is drafted in consistency of latest modified national standard GB 17820 “Natural gas”, and this draft will rule the gas quality entering long-distance transportation gas pipeline. The great progress exhibits on the criterion of calorific value and total sulfur etc in this standard will make great influence on natural gas treatment and analysis. Especially change by order of magnitude will fit the environmental need of the people. Moreover, the criterion of hydrogen and carbon monoxide will expand the application scope of this standard to all the type of gas entering long-distance transportation gas pipeline.
Key words:  natural gas  long-distance transportation gas pipeline  quality requirement  total sulfur  hydrogen
