Dear Experts,
I have to feed a leaching reactor that needs 400 Sm3 oxygen per day. It is not possible to supply oxygen by pipeline so it has to be stored, and besides the requried quantity is so small.
The oxygen has to be supplied @ 5 barg. What is the normal practice? I don't think cryogenic storage can be a good idea, becauase of the cost and the requried upstream pressure.
If a pressurized tank is considred, ho should we transfer oxygen to the tank? As I understand storing oxygen can be chalenging because of safety issues.
Thank you.

Hi ,
I've attached a link about Oxygen PSA to support your query .
You did not supply indication about the purity of O2.

I did this very application for many clients of our industrial oxygen sales program when I was in my youth. Times have not changed for small consumers and the same techniques and hardware is still used with success.
The bulk high purity oxygen transport from a supplier is made using tube trailers. These are flat-bed trailers that have a stack of high pressure oxygen tubes on the bed and manifolded together. The tubes, when filled to capacity for transport to your consumption site, are at approximately 200 atmG. The oxygen is typically 99.5% volume purity (minimum).
The supplier usually leases (or sells to you) a bank of similar high pressure tubes that are stacked (usually in square fashion) on a steam frame or skid. These, too, are also manifolded together and can be filled with pressure up to 200 atmG.
The transported oxygen is transferred from the tube trailer to your stationary storage bank by using the system of cascaded pressure – i.e., the higher pressure tube trailer transfers gas to lower-pressure storage tubes by pressure difference. High pressure, SS braided flexible hoses are used as the transfer connections between the trailer and the storage bank. All equipment is ultra-clean for oxygen service and maintained that way.
You use a series of pressure regulators to feed your process from the storage bank to your process at the desired process pressure (which is well below 200 atmG). This type of operation is done safely all around the world every day.
You can see illustrations and examples of this transport system at the following web sites:
