英文摘要: H2S has great effect on the transportation, storage and use safety of natural gas. It is an absolutely necessary measuring project for natural gas quality control. So it has important significance to quickly and precisely monitor H2S content. The summary is made about the present national and international standard test method for H2S in natural gas. Based on these, sensor-based type for quantifying H2S including semiconductor metal oxide, electrochemical and optical sensor are re-viewed. Different quality-assurance parameters (e.g., operating principles, limit of detection, re-sponse time and common operating range of concentration) are evaluated and compared. Finally, the limitations and the future prospects of these sensor-based methods are highlighted.
中文摘要: H2S对天然气的运输、贮存及使用安全会产生破坏性的影响,其含量是天然气检测必不可少的项目,快速准确测定其含量具有极其重要的意义。本文对天然气中H2S检测所用到的国内国际标准进行了总结分析。在此基础上,综述了满足快速定量检测H2S的半导体氧化物、电化学和光学传感器研究进展,比较各种H2S检测传感器的操作标准(如操作原理、检测限、响应时间、检测浓度范围)。最后,探讨各种传感器的不足并指出今后的发展方向。
