Solubility of Air in liquid CO2
Solubility of Air in liquid CO2
(OP)
I am trying to find a chart/table for the solubility of air in liquid CO2. My problem is how will I know the purity of liquid CO2 after being liquefied in a condenser.
Can anyone help me on this.
Thanks

What I am trying to find out is how soluble is air with liquid CO2 at 250 psig, -8degF?
Just imagine an atmospheric water with oxygen being soluble at about 9 ppm, this is just the as the case with liquid co2 right?

RE: Solubility of Air in liquid CO2
Acording to NIST, at 250 psia, air will not liquify until -251F so now I understand your question.
I just don't have any idea how to find the Henry's Law constant for air and liquid CO2. None of my resources have anything about liquid CO2 at all. The detailed study the effects of changing temperature of pure water on the rate of solubility is the subject of conflicting papers, I don't think that this topic has reached the maturity where anyone is looking at different solutes. Sorry.
