【摘要】：尽管目前国内检测总硫含量的诸多方法都准确可靠,但仍存在检测频率低、周期长、不能及时给出检测结果等不足。为此,在总结天然气总硫含量检测相关标准的基础上,探讨了天然气总硫含量在线检测标准方法及其相关技术,确定了上述标准方法和相关技术的原理,进而提出了制订我国天然气硫化合物和总硫含量在线检测标准方法的建议。结论认为:(1)实现天然气总硫含量在线检测是未来发展的必然趋势;(2)鉴于国内尚无天然气总硫含量在线测定方法标准,建议借鉴和参考ASTM D7165-10(2015)《气相色谱法在线测定气态燃料中的硫含量》、ASTM D7166-10(2015)《用总硫分析仪在线测定气态燃料中的硫含量》和ASTM D7493—2014《气相色谱和电化学检测法在线测定天然气和气体燃料中硫化合物》等国外标准,适时制订我国的相应标准。
[Abstract]:Although many methods for the determination of total sulfur content in China are accurate and reliable, there are still some shortcomings such as low detection frequency, long period and failure to give the test results in time. Therefore, on the basis of summarizing the related standards for the detection of total sulfur content of natural gas, this paper discusses the on-line detection standard method and related technology of total sulfur content of natural gas, and determines the principle of the above standard method and related technology. Furthermore, it is suggested that the standard method for on-line detection of sulfur compounds and total sulfur in natural gas in China. Conclusion: (1) it is an inevitable trend in the future to realize the on-line determination of total sulfur content in natural gas.) in view of the absence of domestic standard for on-line determination of total sulfur content in natural gas, It is suggested to refer to ASTM D7165-10C2015) < determination of sulfur in gaseous fuel by Gas Chromatography > ASTM D7166-1015) < On-line determination of sulfur in gaseous fuel by Total sulfur Analyzer > and ASTM D7493-2014 < days of On-line determination by Gas Chromatography and Electrochemical Detection Natural Gas and Gas fuel sulfur compounds. Timely formulation of China's corresponding standards.
