A fluid is called “supercritical” when both its pressure and temperature are over its critical pressure and temperature. It is monophasic and exhibits specific properties, different from those of liquids and gases.
Often used as supercritical fluid, Carbon Dioxide presents numerous advantages :
- Non toxic
- Low chemical reactivity
- Critical conditions easy to reach
- High diffusivity.
Supercritical fluids have numerous applications from food industries to pharmaceuticals, cosmetic use …
