Supercritical fluid extraction - Wikipedia

Supercritical fluid extraction, (SFE) is the process of separating one component (the extractant) from another (the matrix) using ,supercritical, fluids as the extracting solvent.Extraction is usually from a solid matrix, but can also be from liquids.SFE can be used as a sample preparation step for analytical purposes, or on a larger scale to either strip unwanted material from a product (e.g ...

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.

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.

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 ...

When a gas such a carbon dioxide is contained under high pressure and heated, there are changes to its physical properties. It becomes a supercritical fluid (SCF). Under these conditions, the gas possesses the solvating power of a liquid and the diffusivity of a gas. Its density is similar to the density of a liquid and its very low, surface tension, ...

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.
