Start up the gas separation unit to introduce air
Thread Content
I would like to ask everyone: can steam be used to drive out air when starting up a vapor distribution unit?
Normally nitrogen is used; I want to replace it with steam, but I’m not sure what the disadvantages are
Sigh,,, these days everyone speaks in simplified language,,, what do you mean by a “gas distribution device”? Is it an air separation unit or something else? Why expel air? Catch up or drive away? ? ? Can you type a few more words? ? It looks confusing.
It’s possible to do so. The advantages are fast replacement and low cost, while the disadvantages are that it’s necessary to time the feeding precisely; otherwise, there will be severe negative pressure in the tower or liquefied gas will leak from the vent. Additionally, a long time is required for water separation
