Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a gas chromatographic analysis method for the determination of H_2S and carbonyl sulfide content in coal-based syngas. The online dilution system was diluted to 5 concentrations, the relative retention time was qualitative, and the working curve was quantified by external standard method. The logarithm of the H_2S content and the logarithm of the peak area have a good linear relationship in the range of 0.07~0.30 mg/m3, and the correlation coefficient r2 is 0.9998; the logarithm of the carbonyl sulfide content and the logarithm of the peak area are in the range of 0.13~0.53 mg/m~3 The internal linear relationship was good, and the correlation coefficient r~2 was 0.9979. The detection limits (S/N=3) of H_2S and carbonyl sulfide were 0.04 mg/m~3 and 0.07 mg/m~3, respectively; the quantification limits (S/N=10) of H_2S and carbonyl sulfide were 0.08 mg/m~3, respectively. m~3 and 0.12 mg/m3~; the recoveries were all between 96% and 103%; the same sample was repeated 8 times, and the relative standard deviations were all less than or equal to 8.1%; compared with SCD gas chromatography, the deviation was in line with gas chromatography Quantitative requirements of the law.
