摘　　要：采用PLOT/Al_2O_3石英毛细管气相色谱柱和氢火焰离子化检测器,建立了炼厂气中单体烃组分含量测定的毛细管气相色谱法。当炼厂气中单体烃组分的含量大于或等于2.1％时,RSD≤0.95％;当炼厂气中单体烃组分的含量为0.5％～2.1％时,RSD为0.95％～10.0％;当炼厂气中单体烃组分的含量为0.2％～0.5％时,RSD为10.0％～25.0％。该方法对单体烃组分的测定结果与行业标准SH/T0230-92《液化石油气组成测定法》的测定结果基本一致。The method for the determination of the monomer hydrocarbon components in the refinery gas by capillary gas chro-matography was established by using PLOT/Al2O3 quartz capillary chromatographic column and hydrogen flame ionization detector. When the content of the monomer hydrocarbon component in the refinery gas is ≥2.1% , RSD is≤0. 95% . When the content of the monomer hydrocarbon component in the refinery gas is 0. 5%~2.1% , RSD is 0. 95%~10. 0%. When the content of the monomer hydrocarbon component in the refinery gas is 0. 29%~0. 5% , RSD is 10. 0%-25. 0% . The determination results of the method are ba-sicallv consistent with those of industry standard method SH/T 0230-92.
