摘要:

对焦油蒸馏真空系统尾气管道堵塞问题进行了分析,确定堵塞物主要为铵盐。将真空尾气洗涤液由甲基萘油改成温水,并对生产操作进行了改进,解决了焦油蒸馏真空管道堵塞的问题。

Abstract:

The problem of blockage in the tail gas pipeline of tar distillation vacuum system is analyzed,and it is found that the main reason for the blockage is ammonium salt.By replacing the washing liquor methylnaphthalen with warm water,and improving the operation conditions,the problem of blockage in the tail gas pipeline of tar distillation vacuum system is solved.
