Since I am a refrigeration ingineer, I flow N thru copper while brazing. WHY? Inert gas keeps pipes cleaner. Then I store apples. Lime absorbs N for "N" Bank if machinery breaks down.
We use about 10 tons of bagged lime in each of our CA cold storages, here.
So, after the CA rooms are emptyied out of apples, we have NITROGEN CHARGED LIME. Good for orchard land.
Moral to the story.....my 9N is not designed for NITROGEN CHARGED GASOLINE.
