Frequently Asked Questions

supercritical co2 extraction

Supercritical carbon dioxide is a fluid state of carbon dioxide where it is held at or above its critical temperature and critical pressure.

Carbon dioxide behaves as a gas at ambient temperature and pressure conditions and behaves as a solid when frozen. If the temperature and pressure are increased from ambient conditions to be above the critical point for CO2, it adopts properties between that of a gas and liquid.

More specifically, it behaves as a supercritical fluid above its critical temperature 31.10 °C and critical pressure of 73.9 bar expanding to fill its container like a gas but with a density like that of a liquid.

In this state, carbon dioxide exhibits solvating properties of a liquid and the diffusivity of a gas. This makes it a powerful medium for extraction of natural oils from organic materials.

supercritical co2 extraction

Supercritical Fluid Extraction of solids, is generally operated in batch mode on milled materials (or pellets, granulates), with food grade carbon dioxide as solvent. The equipment consists of two or more extractors operating above the CO2 critical pressure, and two separators where the extract and the CO2 are separated prior to the CO2 being recycled.

The supercritical CO2 Extraction process consists of first raising the temperature and pressure of the carbon dioxide gas till it reaches super critical state. This is done using a high pressure pump and a heater. The organic raw material is loaded into the extractors through which the super critical CO2 passes. Based on the components present in the raw materials, and the pressure-temperature settings, the supercritical CO2 extracts the oils from the raw materials and passes through a series of pressure regulator valves to enter the separators. The two separator pressures are controlled individually to separate the different components of the extract. Once the extracted oil is separated from the CO2 which escapes in the form of a gas, the oil is collected in collection vessels while the extract free Carbon dioxide is recycled by condensing and storing in the CO2 tank in the liquid form. This CO2 is then reused and the entire cycle is repeated for the duration of the batch.

CO2 extraction is revolutionizing essential oil production, offering superior quality and purity. This method uses supercritical carbon dioxide to selectively extract compounds from plants leaving no toxic residues. When used as an essential oil extractor, the CO2 extraction machine preserves heat-sensitive molecules, resulting in oils that closely mimic natural plant oils. Precision is the main USP of the process. It ensures consistent, high yield extractions, appealing to both small and large producers. Its eco-friendly nature aligns with growing demand for sustainable products.

CO2 extracted essential oils are valued for their potency and authentic scent profiles. The method’s versatility allows extraction of various plant compounds, enabling innovation. CO2 extraction represents the cutting edge in essential oil technology, balancing quality, efficiency, and sustainability.

Supercritcal CO2 extraction uses CO2 to isolate desired compounds. Pressurized and heated CO2 acts as a unique solvent with tunable soluble power. This helps it efficiently extract target molecules without dissolving unwanted products from the raw material.

CO2 machine extraction involves:

  • Material Preparation: The plant material is ground and loaded into an extraction vessel.
  • Taking CO2 Supercritical: CO2 pressure and temperature is increased to take it to its supercritical state.
  • Extraction: Desired compounds are extracted or dissolved into the supercritical CO2
  • Separation: CO2 returns to gaseous state, leaving a concentrated extract.

Advantages of supercritical CO2 extraction:

  • Clean and Safe: No harmful solvent residues.
  • Selective Extraction: Tailored for purer extracts.
  • Preserves Quality: Moderate temperatures and targeted dissolution minimize degradation.

Supercritical CO2 extraction offers a refined approach when used as an essential oil extractor. It utilizes moderate temperatures and eliminates harsh solvents, resulting in:

CO2 machine extraction involves:

  • Preserved Essence: Delicate compounds remain intact, producing a more accurate compound.
  • Purity: As CO2 extraction for essential oils is a solvent-free procedure, it ensures a purer and safer essential oil.
  • Expanded Availability: Previously unavailable oils from heat-sensitive raw material has become accessible using CO2 extraction.
  • Environmentally Friendly: The recirculation of supercritical carbon dioxide minimizes environmental impact because it is not vented out to the atmosphere.

On account of all these reasons, this process represents a significant advancement in the efficient extraction of essential oils.
