Tank blanketing

Seems plausible. Has anyone tried it for long term fuel storage?

Rail tank cars use it all the time to stabilize products that need it. Usually Nitogen is used.

You will need a rated pressure container to do it.

We built a couple of these tanks for a company called Praxair. They were used for liquid nitrogen. Very expensive; don't know how if what we did would have a diy application.

Trivia: the largest use of the liquid nitrogen was for recycling tires. Froze them and crushed them like stone.

And this would work for long term storage

Also need a bleeder valve on top to relieve nitrogen before dispensing petroleum.

I would just fill container plumb full to limit off gassing and degradation. But that would require a PRD to be safe.
