design of nitrogen storage tanks

[Jens12]

Hello,

I have to do a cost estimation for N2 storage tanks and have long expirience in the calculation of pressure vessels. Unfortunately I don't have a clue of the design of N2 storage tank. Are there any internals or is it just a vessel like a Compressed Air Tank (I'm aware of the low temp. problems). What about double wall design with vacuum insulation. Does anybody can provide manufacturers ?

best regards

What size tank are you considering?

 

[Jens12]

a 12 m3 nominal capacity (liquid N2) tank.

Here is one vendor that I'm very familiar with and have visited their plant numerous times.

Jens,

At 12 m3 (about 3200 gallons) you can get a small commercially built vertical storage unit....

The VS300NC shoud do the job (Chart industies)...its 86" diameter and 228 inch height

With a cost of around US$15/gallon, I would ballpark such a tank (with pipework) at about $46K....

My opinion only

That should be the "VS 3000NC".....
