This doesn't really address your question, but maybe it will help.  We 
use a lot of nitrogen for various systems around our accelerator based 
atomic collisions physics lab.  We used to go through several nitrogen 
cylinders a week.  Then we "discovered" that the boil-off gas from our 
liquid nitrogen tank was quite pure.  So now we have this boil-off gas 
piped throughout the lab at about 15 psi.  It works great for us.  
Last time I was at Chalk River (1992), I seem to remember a couple of 
LN2 tanks on the grounds.  Are they close enough for you to pipe the 
boil-off into your lab?
