Maintenance considerations for medium and low-temperature operating equipment in large air separation units
Thread Content
I would like to ask everyone about any special considerations for the maintenance of low-temperature equipment in large air separation units! ! What are some good suggestions for ensuring personal safety when performing maintenance in cold environments? Also, what are effective ways to deal with cold leaks in cryogenic tanks? Thank you all! I beg you! This post was last edited by 156026692 on 2009-2-5 21:09]
It is recommended to look in the cryogenic area; relevant materials can be found there.
When a cold box cools down, the system should be equipped with settings for the cooling time, the cooling pressure, and the temperature reached after cooling. It is important to avoid excessive pressure or too rapid cooling; otherwise, the cold box will soon become unusable and have to be sent to a scrapyard.
