Thread Content
Dear experts, I have a question: when a coking plant is put into operation for the first time, the entire facility needs to be purged. So, what gas should be used to displace the purge steam after purification, and what gas should be used for flushing? Thank you!
Replace the steam with gas for purging, and then use gas for pressurization
