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

They do make steam-jacketed vents, contact the vent manufacturers for those.
Overflow piping is optional, depends on the application as to whether an overflow is used.
