摘要
建立了用HP7890A系列气相色谱仪分析炼厂气的方法,本方法操作简单,一次进样测定炼厂气组成,分析时间在7 min以内。炼厂气的分析由三个通道完成,FID A通道用于分析C1～C4和C5+烃类,TCD B通道用于分析永久性气体,包括CO2、H2S、O2、N2和CO,TCD C通道单独用于分析氢气。数据利用安捷伦工作站采集和输出,采用外标面积归一化法进行定量计算。结果表明,该方法准确、快速、简便,适用于炼厂气分析。
A method is established for analyzing refinery gases by HP7890A series gas chromatograph. The operation of this method was simple, all components of refinery gases can determined by injecting sample only once within 7 minutes. The refinery gases were analyzed by three channels. The FID A channel is used to analyze the hydrocarbon components from C1～C4 and C+5, TCD B channel is used to analyze inert gases, including CO2, H2S, O2, N2, CO, and TCD C channel is only used to analyze hydrogen. The chemstation of HP7890A can collect and output analysis data. External standard-area normalization was used in quantitative calculation. The result shows this method has the advantages of accuracy, rapidity and simplicity, being suitable for refinery gases analysis.
