If steam is used to push it out, water hammer may occur; if nitrogen is used instead, will the pipeline vibrate? Please share your thoughts, thank you, extra points!
Blow it out slowly with nitrogen; it should work
No problem. First, pump out the large amount of solvent; send the remaining solvent to the underground solvent tank, and then use nitrogen to purge away what’s left
With nitrogen, there is no issue of water hammer and the pipelines do not vibrate. However, nitrogen treatment is not as effective as steam purging; it is best to first use nitrogen to remove any remaining amine solution and then switch to steam purging. Attention must be paid to environmental protection and personal safety!
