CO2 SATURATION TABLE 1

[dkm0038]

Does anyone know where I can find a saturation table for co2 for temperatures above 304.128 K. Everyone I find ends at this temperature. I know its CO2's critical temp but I am going to use it at a pressure less than its critical pressure.

Can anyone help.

If you are looking for thermophysical properties of CO2 vapor, I suggest:

25362,

I am well aware of NIST, if you check out their saturation properties for CO2 vapor you'll notice that it doesn't help with my question above

 

[25362]

Can you explain your meaning of the term saturation for a vapor above its critical temperature ?

water saturation?

At that temperature and 1050 psig (around 7 MPa) saturation no longer means anything. From that point draw a vertical line (that is the liquid/dense phase boundary) and a horizontal line (the gas/dense phase boundary).

Dense phase CO2 is really odd stuff. The density approaches liquid and the compressibility approaches gas. Several patents have been issued to use this stuff for a dry-cleaning solvent because it has amazing surfactant properties, but you really don't want minimum wage dry-cleaning workers messing with those pressures.

What are you doing with CO2 that you don't know this?
