硫磺急冷塔出口预处理系统的改进

Improvement of pretreatment system for sulfur recovery quench tower outlet

某炼油厂硫磺回收装置急冷塔出口的氢含量测定选用2000型在线氢色谱分析仪。由于样品预处理系统存在问题,影响了装置的长周期运行。预处理系统改进后,采用小型LOGO!逻辑控制模块为核心,来控制样品的预处理系统,可自动完成整个预处理系统脱水、除尘,无需人为的干预,确保了在线氢色谱分析仪长周期运行。

2000-type online hydrogen chromatographic analyzer was selected for determination of hydrogen content at the outlet of sulfur recovery unit of a refinery.The problem existed in the sample pretreatment system affected long-period operation of this unit.After pretreatment system improvement,small-scale LOGO ! Logic Control Module is used as core to control sample pretreatment system,thus the whole pretreatment system dehydration and dedusting can be accomplished,no people intervention is needed,and long period operation of online hydrogen chromatographic analyzer is ensured.
