3/8/2017, · What Is Supercritical Carbon Dioxide (ScCO2)? At standard temperatures and pressure, carbon dioxide is a gas. At 60.4 psi it’s a liquid and at -78C at standard pressure, it’s a solid (dry ice). When heated to above 31.10C (critical temperature) and at 1,071 psi (critical pressure) or higher, it has the properties of both a gas and liquid.

The reason of this cleanness and low-pressure drop is that Supercritical CO2 has the same carrying capacity as oil, but the viscosity is 10 times lower than water. This makes it a lot better than the conventional flushing systems that has a pressure drop of over 60.000 PSI over ¼” OD 13.000-meter Control-Line, were SCCO2 has a drop of below 3.000 PSI and maintains a Reynolds No. of …

So anything which dissolves above 31 degrees would require supercritical CO2 to extract. And you need a vessel which will contain over 1100 PSI regardless of which you're using. My experience is limited and outdated -I haven't worked as a chemist for over 30 years- but if I understand it correctly there is a great deal of variability as to what temperatures are tolerated by the various oils.
