Supercritical Fluid Extraction (SFE) technology is a new emerging green separation technology with wide application. Supercritical fluid refers to the state of an object when it is above its critical temperature and critical pressure. This fluid has the advantages of both liquid and gas: high density, low viscosity, small surface tension, and very high solubility. All those characteristic helps go deep into the matrix of the extracted material, making it very effective extraction solution. The solubility can change dramatically with the change of pressure and temperature. These properties make supercritical state fluids a very good extracting media.

The principle of supercritical CO2 fluid extraction (SFE) separation process is based on the relationship between the dissolving capacity and density of supercritical CO2 fluid. In the supercritical state, the supercritical CO2 fluid contact with the substance to be extracted, so that it selectively extracts ingredient based on their polar size, boiling point, and molecular size. The supercritical CO2 fluid extraction process is comprised of extraction and separation process.
