GB/T 33443-2016Determination of hydrogen sulfide carbonyl sulfide methanethiol and dimethyl sulfide in coal-based syngas—Gas chromatograph (English PDF)

1 Scope

This standard has determined the use of gas detector with flame photometric detector (FPD) determination of coal-based synthesis of hydrogen sulfide, carbonyl sulfur, methyl sulfide

Alcohols, methyl sulfide methods, reagents and materials, apparatus, sampling, assay steps, results calculations, precision, and test reports.

This standard applies to coal-based syngas hydrogen sulfide concentration of not less than 0.08mg/m3, carbonyl sulfide concentration of not less than 0.12mg/m3, methyl sulfide

Alcohol concentration of not less than 0.08mg/m3, methyl sulfide concentration of not less than 0.07mg/m3 determination.
