  • Patent number: 11083979
    Abstract: A separation method and a separation apparatus for a solvent extracted by supercritical extraction. The separation method increases a solvent recovery rate by minimizing the amount of a solvent to be evaporated and lost since the pressure of a solvent is reduced by arranging two or more separators in series. The method includes: introducing a fluid having passed through a supercritical extractor into a first flash vessel; introducing the fluid which has passed through the first flash vessel into a second flash vessel; and discharging and recovering the carbon dioxide and the solvent which have passed through the second flash vessel, respectively. The pressure of the first flash vessel is 40-100 bar, and the pressure of the second flash vessel is 1-30 bar. The fluid includes carbon dioxide and a solvent.
