天然气乙炔炉喷油裂解气杂质成分的GC-MS分析

Analysis of impurity of spitting gas of natural gas ethyne stove by GC-MS

利用气相色谱 质谱联用仪 (GC MS)对天然气旋焰乙炔炉余热喷直馏汽油和凝析油裂解气的杂质成分进行分析。从两种裂解气中 ,各分离鉴定出 1 7种主要未知杂质组分。结果表明 ,两种裂解气杂质成分相同而含量不同 ,凝析由裂解气的杂质成分含量比直馏汽油裂解气的略大 5 % ,为凝析油的回收利用提供了可靠依据。

The compounds of splitting gas of distilled gasoline and condensable gasoline produced by natural gas ethyne stove were analyzed by gas chromatography mass spectrometry.There were seventeen impurity compounds in each gas and the compositions of both gases were the same.The content of impurity compounds in splitting of condensable gasoline were more than in splitting gas of distilled gasoline.
