I Mixing CO2 and N gasses.

  1. Oct 20, 2016 #1
    I wish to fill a 60 cf tank with both CO2 and N at a 25% - 75% ratio. I have been told by my supplier that if I can tell them the "Recipe" for my size tank that they could make this happen for me.
    What I need to know is the amount of liquid CO2 (measured in pounds) that would be placed into the tank first and then the amount of N that would then be put 'on top' to reach my desired blend.

    Hello Jl,

    Would that be a mass ratio or a mole ratio ?
    What's in the tank initially ? How do you get it out ?
