Thus, the difference between traditional distillation and supercritical extraction is that instead of heated water or steam, CO2 is used as a solvent in the latter method. The supercritical extraction process operates at temperatures between 95 to 100 degrees F whereas steam distillation operates at temperatures between 140 to 212 degrees F.

Types of CO2 extraction (supercritical & subcritical ...

Most often we hear about supercritical CO2 extractions, but that’s actually only one method of CO2 extraction. You can also perform subcritical CO2 extractions, and ‘mid-critical’ extractions, a general range between subcritical and supercritical. Subcritical (low temp, low pressure) CO2 extractions take more time and produce much smaller yields than supercritical, but they retain the essential oils, …
