Supercritical Extraction Technology

Supercritical fluid extraction is the world's most advanced physical extraction technology, referred to as SFE (supercritical fluid extraction). At lower temperatures, when the gas pressure is continuously increased, the gas is converted into a liquid. When the pressure increases, the volume of the liquid increases. There is always a critical temperature (Tc) and critical pressure (for a particular substance). Pc), above the critical temperature and critical pressure, the material does not become liquid or gas, which is the critical point. In the range above the critical point, the matter state is between the gas and the liquid, and the fluid within this range becomes a supercritical fluid (SF). Supercritical fluids have strong penetrability similar to gases and large density and solubility similar to liquids, have good solvent properties, and can be used as solvents for extraction and separation of monomers. Supercritical fluid extraction (SFE) is a high-tech technol
