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.
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?
