浩瀚硫专用柱HH一sulfide-III气相色谱法测定焦炉气中硫化物
浩瀚硫专用柱HH一sulfide-III气相色谱法测定焦炉气中硫化物 详细信息:
名称:硫化物专用柱
固定相:专用
规格:3m*3mm
型号:HH一sulfide-III
应用:硫化氢,羰基硫,二硫化碳,噻吩,甲硫醚,甲硫醇,乙硫醇,乙硫醚,二甲er硫等9种硫化物的测定
焦化生产产生的焦炉煤气经净化产系统净化回收后,进入甲醇生产系统合成甲醇,甲醇生产系统对焦炉气中硫化物含量的要求特别严格,要求将硫化物脱除到0.1ppm以下才能进入转化炉,否则会严重影响催化剂的使用寿命,因此在炼焦及甲醇生产系统中准确、快速测定焦炉气中硫化氢含量尤为重要。
而目前,相当一部分实验室采用的是化学法中的碘量法进行测定,该方法分析时间长(2h),且当干扰物质存在时易受其影响,测定结果的准确性较低。
浩瀚色谱(山东)应用技术开发有限公司通过大量对比实验后发现,色谱法在检测焦炉煤气中的硫化氢时要优于化学法,因此使用气相色谱GC-790plus系列气体微量硫分析仪测定焦炉煤气中的硫化氢含量。该方法具有简单、方便、快速等优点,准确度、精密度都较高,而且不受干扰物质二氧化硫的影响,完全满足成分复杂的焦炉煤气中硫化氢的测定。

Determination of Sulfide in Coke Oven Gas by Haohan Special Column HH-sulfide-III Gas Chromatography
Determination of Sulfide in Coke Oven Gas by Haohan Special Column HH-sulfide-III Gas Chromatography Details:
Name: Special column for sulfide
Stationary Phase: Dedicated
Specifications: 3m*3mm
Model: HH-sulfide-III
Application: Determination of 9 kinds of sulfides such as hydrogen sulfide, carbonyl sulfide, carbon disulfide, thiophene, methyl sulfide, methyl mercaptan, ethyl mercaptan, ethyl sulfide, dimethyl sulfide, etc.
After the coke oven gas produced by coking production is purified and recovered by the purification production system, it enters the methanol production system to synthesize methanol. The requirements for the content of sulfide in the coke oven gas in the methanol production system are very strict, and the sulfide content is required to be removed to less than 0.1ppm before entering the methanol production system. Otherwise, it will seriously affect the service life of the catalyst. Therefore, it is particularly important to accurately and quickly determine the hydrogen sulfide content in coke oven gas in coking and methanol production systems.
At present, a considerable number of laboratories use the iodometric method in the chemical method for determination. This method has a long analysis time (2h), and is easily affected by the presence of interfering substances, and the accuracy of the determination results is low.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. found through a large number of comparative experiments that chromatography is better than chemical methods in detecting hydrogen sulfide in coke oven gas. Therefore, gas chromatography GC-790plus series gas trace sulfur analyzers are used to determine coke The hydrogen sulfide content in the furnace gas. The method has the advantages of simplicity, convenience and speed, high accuracy and precision, and is not affected by the interfering substance sulfur dioxide, which fully satisfies the determination of hydrogen sulfide in coke oven gas with complex composition.
