焦爐氣制取LNG生產過程中需嚴格控制合成氣中的硫含量,以期增加合成催化劑的使用壽命。
浩瀚色譜（山東）應用技術開發有限公司采用氣相色譜儀-硫化學發光檢測器(GC-SCD)方法,測定了焦爐氣制LNG過程中痕量形態硫化物及總硫含量,并結合實際,討論了分析過程中需注意的問題。標準氣校準,計算各種組分的檢出限均低于10.00×10-9(體積分數),總硫含量33.00×10-9。含硫組分的標準曲線相關性均優于0.996。相對標準偏差(RSD,N=7)均小于7%。合成氣樣品測定過程中,在接近檢出限的情況下,相對標準偏差小于12%。本方法可很好地滿足工廠生產控制的需要。

硫化氫，羰基硫，二氧化硫，二硫化碳，柱效高，分離好，結果滿意。

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.
