In the production process of coke oven gas to LNG, the sulfur content in the synthesis gas needs to be strictly controlled in order to increase the service life of the synthesis catalyst.
Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. used the gas chromatograph-sulfur chemiluminescence detector (GC-SCD) method to determine the trace sulfide and total sulfur content in the process of coke oven gas to LNG, and combined with actual conditions, Discuss the problems that need to be paid attention to in the analysis process. Standard gas calibration, calculated that the detection limits of various components are lower than 10.00×10-9 (volume fraction), and the total sulfur content is 33.00×10-9. The correlation of the standard curve of sulfur-containing components is better than 0.996. The relative standard deviations (RSD, N=7) were all less than 7%. In the process of synthetic gas sample determination, the relative standard deviation is less than 12% when it is close to the detection limit. This method can well meet the needs of factory production control.

Hydrogen sulfide, carbonyl sulfide, sulfur dioxide, carbon disulfide, high column efficiency, good separation, and satisfactory results.
