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 C_1～C_4 and C_5~+, TCD B channel is used to analyze inert gases, including CO_2, H_2S, O_2, N_2, 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.
