What is Supercritical CO2?

Supercritical CO2 refers to carbon dioxide in a state where it behaves like both a gas and a liquid. In this state, CO2 is typically maintained at pressures above 73.8 bar and temperatures above 31.1°C. This state allows CO2 to have unique solvent properties that are ideal for various extraction applications.

Key Properties of Supercritical CO2

• Density: Supercritical CO2 has a density similar to that of a liquid, allowing it to dissolve compounds effectively.

• Viscosity: The low viscosity of supercritical CO2 allows it to flow easily through porous materials, aiding in efficient extraction.

• Solubility: The solubility of compounds in supercritical CO2 can be adjusted by controlling the temperature and pressure, making it a highly versatile solvent.

• Non-toxic and Environmentally Friendly: CO2 is non-toxic, and its use as a solvent in extraction processes does not produce harmful residues, making it a safe and eco-friendly option.

Applications of Supercritical CO2

• Cannabis Extraction: Supercritical CO2 is used to extract cannabinoids like THC and CBD from cannabis plants.

• Essential Oil Extraction: CO2 is used to extract essential oils from plants, maintaining the integrity of their delicate compounds.

• Food and Beverage Industry: CO2 supercritical fluid is used to extract flavors, colors, and natural preservatives from food ingredients.

Conclusion

The unique properties of supercritical CO2 make it an ideal solvent for extraction processes. Its ability to dissolve compounds efficiently while remaining non-toxic and environmentally friendly has made it a widely used tool in various industries.
