焦炉气制取LNG生产过程中需严格控制合成气中的硫含量,以期增加合成催化剂的使用寿命。
浩瀚色谱（山东）应用技术开发有限公司采用气相色谱仪-硫化学发光检测器(GC-SCD)方法,测定了焦炉气制LNG过程中痕量形态硫化物及总硫含量,并结合实际,讨论了分析过程中需注意的问题。标准气校准,计算各种组分的检出限均低于10.00×10-9(体积分数),总硫含量33.00×10-9。含硫组分的标准曲线相关性均优于0.996。相对标准偏差(RSD,N=7)均小于7%。合成气样品测定过程中,在接近检出限的情况下,相对标准偏差小于12%。本方法可很好地满足工厂生产控制的需要。

硫化氢，羰基硫，二氧化硫，二硫化碳，柱效高，分离好，结果满意。

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.
