SC fluid extraction is the most effective method for the separation and purification processes of heat-sensitive compounds.
Fluids used in SC fluid extraction are inert solvents. This feature, no hydrolysis, oxidation, or decomposition reaction is observed in the extraction processes carried out under SC conditions.
Continuous feeding of SC fluid into the packed column extractor causes an increase in driving force in extraction processes, which increases the mass transfer rate.
Since the surface tension of SC fluids is very low, they can enter porous solids more easily. Thus, increasing the mass transfer rate reduces operating time.
The dissolving power of SC fluids varies greatly with small changes in temperature or pressure values.
When the extraction process with SC fluids is completed, the fluid can be easily separated from the solute by lowering the pressure. In this method, there is no solvent residue in the product and a new purification process is not required.
The consumption of less solvent and the use of CO2, especially in extraction processes with SC fluids, have revealed processes that are more environmentally friendly.
SC fluid extraction is an effective process in the separation processes of valuable industrial products that are present in low amounts in natural product compositions.
The fluid used in extraction processes with SC fluids can be fed back to the extractor and it is an economic separation process since the solvent loss is reduced.

Super Critical Extraction; It replaces classical solvent extraction methods due to its advantages.
