Under normal circumstances, various sulfides are harmful to health, such as H2S, SO2, COS, CH3SCH3 like, which is the production of coal chemical industry will certainly produce toxic gases. At the same time, these gases have also hindered in the subsequent process, such as a large number of equipment problems, pipe blockage, corrosion, catalyst poisoning, inactivation and produce harmful gases are related. Therefore, strict control of sulfide.
Coal chemical industry during normal operation of toxic gas H2S occupy a larger portion of Tengzhou City Technology Co., Ltd. Xiangying analysis was based on this test GC7990 gas chromatography Determination of trace sulfur coke oven gas, the results indicate that gas chromatography short cycle method, accuracy, precision and strong, simple, rapid, there is a big advantage compared to conventional titration and spectrophotometry is.
通常情况下,各种硫化物都是有害健康的,例如H2S、SO2、COS、CH3SCH3等,它们是煤化工企业生产中必定会产生的有毒气体。与此同时,这些气体在后续过程中也具有阻碍作用,比如设备、管路堵塞、腐蚀,催化剂中毒、失活等大量的问题产生都和这些有害气体有关。所以,严格控制硫化物的。
煤化工企业在正常运行过程中产生的有毒气体中H2S占据了较大部分,滕州市翔鹰分析技术有限公司基于此进行了焦炉煤气中微量硫的GC7990气相色谱试验测定,结果表明应用气相色谱法的周期短,准确度高,精密性强,操作简便快速,相对于传统的滴定法和分光光度法来说存在很大的优势。
