Extraction technology of supercritical fluid is combined technology with traditional distillation technology
It is one of separation technology such as separation from mixture, purification of polymer, medicine from natural plant, active constituent separation from spice.
There are processes of extraction and separation to extract the substance by using solvency of supercritical fluid
Reagent and solvent are dissolved as supercritical fluid by solvency in process of extraction. Supercritical fluid through extraction process is separated to solute by temperature and pressure in process of separation.
In process of extraction, it can selectively extract specific ingredient by adjusting condition(temperature, pressure).
CO2 commonly using for supercritical state is low critical condition and harmless, nonflammable, safety.

Feature of supercritical extraction system
• Low critical point of temperature and pressure(31.0 6degree C, 74 bar)
• High diffusion coefficient(compared with liquid)
• Eco-friendly clean technology to environment and human
• To adjust solubility by control condition of temperature and pressure.
• High technology for high purity and high quality(extraction system)
• Technology of saving energy.
• No waste of solvent(fluid)
• Nontoxic and nonflammable, rare properties.
• Eco-friendly fluid (recycle system)
