Technical Principles of CO₂ Extraction Equipment
A supercritical fluid is a substance maintained above its critical pressure (Pc) and critical temperature (Tc), exhibiting properties intermediate between those of a gas and a liquid. It possesses a density similar to a liquid, viscosity comparable to a gas, and a high diffusion coefficient, making it an ideal solvent.
The solvent strength of a supercritical fluid is influenced by temperature and pressure. By adjusting these parameters, specific components can be selectively extracted based on their solubility. In lower temperature ranges, temperature affects the density of the solvent and the vapor pressure of the solute. In higher temperature ranges, increased solute vapor pressure enhances the extraction rate. The addition of small amounts of polar co-solvents (e.g., methanol, isopropanol; typically ≤10%) can extend the range of extractable compounds.
