       All major iron and steel companies need to analyze the calorific value of coal gas and calculate the calorific value of coal gas to meet the needs of different production departments. At the same time, in order to ensure product quality, it is also necessary to analyze the content of high-purity protective gas components in each heating furnace. Multidimensional gas chromatography uses capillary column and packed column mixed chromatographic column at the same time, and has the advantages of capillary column and packed column. The method of automatic switching of carrier gas is adopted to realize the analysis of hydrocarbons and permanent gases in coal gas of iron and steel enterprises.

        Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. analyzed the accuracy and precision of multi-dimensional gas chromatography to detect gas calorific value components, and studied the multi-point calibration standard curve of gas components. The results show that multi-dimensional gas chromatography has high accuracy and precision in the analysis of coal gas components, and the multi-point calibration curve also has good regression linearity, which can be applied to the analysis of coal gas calorific value and high purity furnace gas composition.
