Purging of hydrogen peroxide pipelines and liquid sulfur pipelines
Thread Content
As the title suggests, what medium is used for purging hydrogen peroxide pipelines and liquid sulfur pipelines? Does anyone know anything about this?
You can take a look at this: Liquid sulfur pipeline purging http://bbs.hcbbs.com/thread-1189559-1-1.html (Source: Haichuan Chemical Industry Forum)
The liquid sulfur pipeline has not been purged; air or nitrogen will be used if it is to be in use.
I consulted a senior engineer from my company who has experience with sulfur; for liquid sulfur, it’s sufficient to use low-pressure steam for cleaning, but steam cannot be used for hydrogen peroxide. The exact method of cleaning is not very clear
