Supercritical Co2 Extraction Process : Seven Application Advantages
The basic principle of supercritical fluid extraction is to dissolve the required chemical components with a supercritical fluid under conditions above the critical temperature and critical pressure, and then reduce the pressure of the fluid solution or increase the temperature of the fluid solution, so that the solute dissolved in the supercritical fluid precipitates due to its reduced density and reduced solubility, thereby achieving the extraction of specific solutes.
