Analysis of Components in Refinery Gas by Agilent 7890A Gas Chromatograph

介绍了用Agilent 7890A气相色谱仪分析炼厂气的方法。采用四阀六柱、双TCD+FID三检测器系统的三通道同时分析炼厂气。其中,FID路通道用于分析烃类组分,一路TCD通道用于分析氢气,另一路TCD通道用于分析永久性气体。经检测并通过校正归一化百分比方法运算得各组分含量。该方法具有快速准确,重复性好,操作方便等优点。

A method was established for analyzing refinery gas by Agilent 7890A gas chromatograph. The refinery gas was separated by four-vale six columns and determined by two TCD＋FID detector three-channel gas chromatography. FID channel was used to determine hydrocarbon, one TCD channel was used to determine hydrogen, another TCD channel was used to determine permanent gas. The determination results were calculated by percentage calibration normalization method. The result shows that this method has the advantages of rapidity, accuracy, highly reprodueible and easy to operate.
