Re: Boiler Piping System

Excellent. Cryogenics works sort of the same way, but in reverse.

Extracting nitrogen is a relatively easy proposition. When one gets down to producing O2, it gets a bit more complicated.

After initial main compression, the waste N2 is used to cool the incoming. It's not a big secret, you can find out how to do it all over the net.

Great post, Steve.
