Dear Experts,

 

I would like to ask a question about the application of gas seals (i.e. velocity or buoyancy type).

 

As per the API 521/537, it appears that the gas seal is only installed in a flare stack. However, I am curious if we can apply a gas seal inside a vent stack (for example inside hydrogen vent stack) to reduce continuous N2 purge gas flowrate.

 

Is this possible and what are the possible benefits and drawbacks of doing so?

Answer depends on the purging purpose. What reason do you purge this vent? If flashback preventimg then answers is yes - gas seal can help.
