Supercritical Co2 Extraction technology is a new subject of modern chemical & industry, and is an advanced separating process arising in the international market at present. The so called supercritical fluid is the fluid when the thermodynamic state is over the critical point (Pc, Tc), and the critical point is the state that the interface between gas and liquid just disappears. There are special physical/ chemical characteristics for the supercritical fluid, its density is near to liquid's, and its viscosity is near to gas', with the big diffusion coefficient, small viscosity and big dielectric constant, etc, the separating result is better, and it's a good solvent. The SFE is that solvent is contacted with the extractant in the extracting cylinder by the high pressure & suitable temperature, solvent will diffuse into the solvent, then in the separator, by changing the operation condition, the dissolved matter will be precipitated, so finish the separating.

Take co2 as the supercritical extraction agent, there are following features for the supercritical device:

a. The applying range is wide, and it's easy to regulate.

b. With well selectivity, by controlling the pressure & temperature, the desired components can be extracted.

c. The operation temperature is low. The operation is by the room temperature, so it's better to treat the heat-sensitive matters. During the extraction, there is no oxygen's oxygenation, no reaction when be lighted, and the product will keep its natural property.

d. The extraction is completed within one step, and CO2will not be remained in the products.

e. CO2 is a gas, no poisonous, tasteless, non-flammable, cheap, and can be recycling used.

f. The reacting speed is fast. 

In recent years, the SFE technology has been rapidly developed, and is mainly used in the extraction & purifying of hops, spice, Chinese traditional medicine, oil & fat, gas and foodstuff, etc.

Advantages:

1) Convenient in operation. Can be used widely.

2) With an excellent optional function. Extracts can be gained optionally by controlling the pressure and temperature.

3) Low operation temperature. Can be extracted near to the room temperature, especially fit for the extracting of thermo-sensitive elements. The possibility of oxidation when contact with oxygen and reaction when meet rays are eliminated. The natural flavor of the extracts can be kept.

4) Extracting media and extracts can be separated easily. No leftover of CO2 on the extracts after extracting operation.

5) CO2 is a nontoxic, flavorless, noncombustible and cheap compound and can be recycle used.
