Features and Advantages
- Low Temperature Separation
A highly pure unaltered extract obtained, without solvent residues and without degradation of quality by high temperature or oxidation. - Non-toxic Solvents
Such as Carbon Dioxide, leave no harmful residue in the extract. - Solubility Variation
Solvent characteristics, such as: viscosity – coefficient of diffusion – dielectric constant and density (capacity) of a gas in the supercritical state, can be varied by simply.increasing or lowering extraction pressure and temperature. - Fractionated Extraction and Separation
Can process both solids in batch mode and fluids in continuous and batch mode. - Inexpensive Solvents
Units can be adapted for various gases and for gas mixtures, or for the preparation of gases with entrainer (e.g. acetone, alcohol, etc.). Recommended gas for extraction is CO2. - Low Energy Process
Electricity is the only form of energy required because there is no solvent distillation and no steam purging of the residue. - Fast Diffusion
Accomplished because of the low viscosity of CO2. - Chemically Inert Solvent
Oxygen is completely excluded from the process because of the closed system design. - No Risk to the Environment
Through the use of the inexpensive extraction agent – CO2. - No Explosion or Fire Hazards
- High Selectivity for the extraction of non-polar compounds.
