Abstract: A procedure for qualitative and quantitative analysis of organic sulfur compounds in natural gas has been established. Chromatographic methods and selective chemical reactions have been used to determine the boiling points and structures of the sulfur compounds. Relative retentions of 12 S-compounds on 4 different liquid phases were given. Experiments on 4 compounds containing different S-group indicate that within certain concentration range, the responses of FPD as expressed by h1/2.w is independent of the nature of the S-group. Thus, a single calibration curve can be used to determine all S-compounds. Comparing with other methods, satisfactory results of qualitative and quantitative analysis of three representative natural gases in Sichuan gas fields have been obtained.

摘要： 建立了采用火焰光度检测器、气相色谱仪的方法,进行天然气中有机硫化合物的定性及定量分析。检测器对硫的敏感度优于2×10~（-12）gS/s,可测出天然气中0.01—0.1ppm的各种沸点低于100℃的硫化物。给出了十二种硫化物在沙鱼烷、苯二甲酸二壬酯、磷酸三甲苯酯及亚氨基二丙腈四种柱子上的相对保留值。进行了四川地区三种不同类型天然气中有机硫化物的全分析,与其他方法相比较,结果是满意的。
