Large capacity O2 tank 3

[shvet]

Good day, forum

Is here someone having experience with cryo industry? Is it normal to store liquid O2 in a large cryo tank let's say 2'000 cubic meters? Volume 100m3 is definitely ok, but 2'000m3... Can someone share a link to a standard/practice where issues like this are discussed?
Please guide me.

The following clause is from API 625

SECTION 1—SCOPE
****
1.2.1 This standard covers tank systems having a storage capacity of 800 cubic meters (5000 bbls) and larger.
1.2.2 Stored product shall be liquids which are in a gaseous state at ambient temperature and pressure and require
refrigeration to less than 5 °C (40 °F) to maintain a liquid phase.
1.2.3 Tank systems with a minimum design temperature of –198 °C (–325 °F) (see note), a maximum design
internal pressure of 50 kPa (7 psig), and a maximum design uniform external pressure of 1.75 kPa (0.25 psig) are
covered.
******
The boiling point of O2 is (–183.00 C) so, API 625 is applicable in your specific case .







Use it up, wear it out;
Make it do, or do without.

Once you go past ~380 m3 (100,000 gal) transportation usually becomes quite difficult for a shop built horizontal ASME vessel tank. 2,000 m3 would probably require either a battery of horizontal tanks or a smallish low pressure flat bottomed tank (API 625 as referenced above).

"Normal" varies widely.

2000m3 is a lot, but depends on your usage.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Let me be more specific

Large single volume cryo tanks is normal in industry, see example of 1'000m3 cryo tank

But this is LIN, while I am dealing with LOX which is more dengerous.

My concerns are related to a hazard arised from large volume of LOX stored (1x2'000m3 or 2x1'000m3 tanks or 3x700m3 - does not matter). I have no experience in such and trying to find one's personal experience - am I going to be the first on planet Earth or there are more like me?

Not the first at least. 3400 m3 sphere at NASA launch site in Florida.

Thank you. That is exactly what I have been looking for.

Here is a fabricator for flat bottom LO2 tanks:

thank you

Spheres are usually selected for high pressure storage, while flat bottom tanks are obviously for LP storage.
