When the acidic water stripping tower loses power
Thread Content
According to the documentation, when the acidic water stripping tower loses power, the steam control valve of the reboiler at the bottom of the tower cannot be closed completely in order to prevent negative pressure from forming in the tower. I have a question: can turning off the steam completely create a negative pressure in the tower?
Acidic gases dissolve in water, and steam is introduced for heating during stripping. In the event of a power outage, a certain negative pressure will be created.
How can negative pressure be created? Could you explain it in detail? Thank you. Looking forward to your reply
I want to know too. I can’t figure it out. Numbers numbers numbers numbers numbers. Numbers digits
After a power outage, when all heating equipment cools down, a negative pressure can develop (if the space is sealed). Ammonia and other substances present in acidic water are highly soluble in water and are more sensitive to temperature changes; as a result, negative pressure is generated more rapidly. There is therefore a reason why steam valves should not be completely closed.
