NaHS Storage Tank

[piestro]

I'm designing a NaHS storage Tank. I want to know what are the basic recommendation for this kind of reagent tanks.
Specially I want to know the vent system, drain and overflow.
I saw some picture with a special vent system but I don´t know how it works.

I'm considering Carbon steel material, maybe stainless steel. all piping in stainless steel 316L.


Thanks in advance

Special venting and fire protection requirements are necessary for NaHS storage. Locating the tank one zip code away from people may be a good idea.

NaHS tanks can be poisonous fume generators if engulfed in a fire

I guess you don't have access to GOOGLE in your country....this was my first hit when searching for "NaHS storage"

Where will this tank be located ? What active volume is required ?

Is this the first process chemical storage tank that you have "designed" ?

I believe that the best tank material would be Nickle 200.....
