Research progress,challenges and prospects of gas chromatography technology for sulfur compound detection in natural gas
摘要
Abstract
Sulfur compounds in sulfur-containing natural gas are toxic and pose environmental pollution risks,so they have a great impact on the safe production,purification,transportation and trading of natural gas.The application of gas chromatography to sulfur-containing natural gas detection can accurately monitor sulfur compound content of natural gas.So far,however,the gas chromatography technologies for detecting sulfur compounds in natural gas have not been systematically analyzed and summarized.After introducing the separation principles of gas chromatography technology briefly,this paper systematically summarizes the application progress and specific cases of gas chromatography technologies in sulfur compound detection in natural gas,and points out the challenges and development trends of gas chromatography technology in the detection of sulfur-containing natural gas.The following results are obtained.First,the automatic injection and pretreatment of gas chromatography injection technology for sulfur compounds in natural gas and the impurity treatment and stable pressure,flow rate and temperature control before injection are beneficial for ensuring the stability of analytical data and need further research.Second,there are currently multiple models of gas chromatography columns available for the separation and analysis of sulfur compounds,and the emergence of new materials and the optimization of analysis methods will further improve the separation and detection of sulfur compounds.Third,thermal conductivity detector(TCD),flame photometric detector(FPD)and sulfur chemiluminescence detector(SCD)are currently the most mature gas chromatography technologies used for the detection of sulfur compounds in natural gas.The combination of multiple detectors and the introduction of new detectors have expanded the application of gas chromatography in natural gas detection.Fourth,standardization construction promotes the development of gas chromatography technologies,and domestic and foreign standards for gas chromatography of sulfur compounds in natural gas are continuously updated and improved.In conclusion,gas chromatography technologies are still in the stage of continuous development and breakthrough.In the future,attention should be paid to improving repeatability and accuracy,promoting automation,intelligence and integration convenience,and continuously improving the gas chromatography technology system,so as to provide strong guarantees for the quality control and safe utilization of natural gas.关键词
