What is Supercritical Fluid? | Hightech Extracts

Supercritical fluid extraction is known to be dependent on the density of the fluid that in turn can be manipulated through control of the system pressure and temperature. The dissolving power of a SCF increases with isothermal increase in density or an Isopycnic (constant density) increase in temperature.

In addition, close to the critical point, small changes in pressure or temperature result in large changes in density, allowing many properties of a supercritical fluid to be 'fine-tuned'. Supercritical fluids are suitable as a substitute for organic solvents in a range of industrial and laboratory processes.

A supercritical fluid is a substance at or above its critical temperature, Tc, and critical pressure, Pc, of the liquid-gas phase boundary. Under supercritical conditions, the density of the fluid varies continuously with changing temperature and pressure, avoiding phase boundaries. The densities a fluid may exhibit in the supercritical regime of ...

What do we call 'supercritical fluid'? As an example, supercritical carbon dioxide refers to carbon dioxide that is in a fluid state while also being at or above both its critical temperate and pressure, yielding rather uncommon properties. The density, viscosity and diffusivity of the fluid are then intermediate between those of the liquid phase and those of the gaseous phase.
