Resources to understand how LN2 tanks work

[Engineer_M]

Hi,
I'm new to learning about how LN2 tanks work. Any information or resources will be greatly appreciated.
I am particularly looking to understand how the delivery pressure works and if the LN2 and GN2 pressures are always the same.

Thanks!

Google Linde, they have pretty good tech resources on their site, or at least used to. You could also check with your local gas supplier.

Last time I was involved, we used a dedicated compressor to supply high-pressure "shop nitrogen" to the plant, fed from the low pressure LN2 dewars. Dunno if that changes, but it might if your capacity requirements are small.

Or look into the people that make tanks such as Chart or MVE.

Do you mean a bulk LN2 tank or the smaller liquid cylinders that are used in laboratories? Either way, Chart is a good place to start for that type of equipment. A typical way to create GN2 from LN2 in both of these types of tanks is with the use of a vaporizer. Chart also sells bulk tank vaporizers (under the name Thermax I think) and liquid cylinder catalogs should talk about how those built in vaporizers work.
