天然气中硫化物检测方法标准的分析探讨

Study on the standard test method for determination of the sulfur-containing compounds in natural gas

含硫化合物特别是H2S对天然气的运输、贮存及使用安全会产生破坏性的影响,因此硫化物的含量是天然气检测必不可少的项目,准确测定其含量具有极其重要的意义。对天然气中含硫化合物检测所用到的国内外标准进行了总结分析,从原理及适用范围等方面对各标准进行了比较,并根据中亚管输天然气含硫化合物检测的实践经验对标准的选择提出建议和意见,以期为天然气相关检测研究提供有益的参考。

Sulfur-containing compounds especially H2S can greatly effect on the transportation,storage and use safety of natural gas.So,it is an absolutely necessary project for measuring natural gas content,which has a very important significance.The summary is made about the present domestic and foreign standard test method for determination of the sulfur-containing compounds in natural gas.Then different standards are compared at different aspects,such as the detection principle,the detection range and so on.At last,some suggestions are presented about the selection of standards for determination of the sulfur content of natural gas on the basis of our practical experience about Central Asia pipeline gas,in order to provide a useful reference for the related study.
