Supercritical extraction with carbon dioxide (SC-CO2) is getting
popular as a cost effective and environmentally friendly method
for extracting useful components such as oils from plant extracts.
Supercritical fluids possess both gas-like and liquid-like qualities,
and the dual role of such fluids provide ideal conditions for extracting
compounds with a high degree of recovery in a short period of
time (Reverchon, 1997; Wang and Weller, 2006).
