This standard specifies the method summary, reagents and materials, instruments, sampling, and determination steps for the determination of hydrogen sulfide, carbonyl sulfide, methyl mercaptan, and methyl sulfide in coal-based synthesis gas by gas chromatography with a flame photometric detector (FPD). , Calculation of results, precision, test report. This standard applies to the concentration of hydrogen sulfide in coal-based syngas not lower than 0.08 mg/m3, the concentration of carbonyl sulfide not lower than 0.12 mg/m3, and the concentration of methyl mercaptan not lower than 0.08 mg /m3, the determination of the concentration of methyl sulfide not lower than 0.07 mg/m3.
