6 Major Advantages And Features Of Supercritical Co2 Extraction Equipment

Supercritical CO2 extraction process

Supercritical CO2 fluid extraction technology is a new separation technology in modern chemical separation, with the characteristics of fast mass transfer rate, strong penetration ability, high extraction efficiency and low operating temperature.

Supercritical extraction uses CO2 as solvent, because CO2 fluid in supercritical state has greater density and dielectric constant, greater solubility for substances, and its solubility changes suddenly when temperature and temperature change. Therefore, it is not only selective for the solubility of certain substances, but also easy to separate solvents and extracts.

The supercritical CO2 extraction device can be used for extracting materials (solids and liquids) at high pressure and suitable temperature under the condition of separator replacement, so that the soluble materials can decompose the target products during the extraction and separation process.
The entire supercritical CO2 extraction device system includes extractor, separator, CO2 high-pressure pump, co-solvent pump, cooling system, heat exchange system, CO2 storage tank, liquid level meter, purification filter system, flow meter, temperature control system, safety protection system, etc. All major mechanical and auxiliary equipment can meet the requirements of supercritical extraction system and process flow.

6 Major Advantages And Features Of Supercritical Co2 Extraction Equipment

  1. Low critical temperature, suitable for the extraction and purification of heat-sensitive compounds.
  2. Able to provide an inert environment to avoid product oxidation and affect the effective content of the extract.
  3. Non-toxic, non-flammable, safe to use, and no pollution to the environment.
  4. No solvent residue, no nitrates and heavy metal ions.
  5. Carbon dioxide can be recycled and reused.
  6. Pressure and temperature can be designed according to requirements.


Supercritical CO2 extraction technology has been widely used in medicine, food, chemical industry and other industries. Supercritical CO2 fluid extraction can be used to separate and extract specific substances from solid media, and can also be used to separate and purify specific components in liquid media.
