CO2 Extraction Process

Supercritical fluid technology is a new separation technology in modern chemical separation. 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.

High-pressure vessel extraction kettle is used to contain the material to be extracted. It is usually made of pressure-resistant materials and can withstand the high pressure of supercritical carbon dioxide.

Supercritical CO2 fluid extraction kettle is one of the keys to the development of supercritical extraction technology. It needs to solve the problems of machinery, heat exchange, fluid transportation and safety assurance caused by the process under high pressure (generally 8-35Mpa or higher). It should be safe, easy to operate, highly versatile, and can be operated continuously on the premise of meeting the production purpose.

The process flow of extracting seabuckthorn oil using supercritical CO2 fluid is: seabuckthorn seeds (peel) → pretreatment → supercritical CO2 fluid extraction → three-stage separation → seabuckthorn oil.

Supercritical CO₂ extraction process is superior to traditional solvent-based methods in terms of efficiency, safety and environmental protection. It can handle a variety of non-polar, high-boiling point substances (such as essential oils, spices, and drug ingredients). It has flexible requirements for temperature and pressure control and is an ideal separation technology in modern industry.

Supercritical CO2 fluid 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. The practical application of Supercritical CO₂ Extraction Process in production is achieved through safe and reliable extraction equipment.

Supercritical CO₂ extraction is a highly efficient, sustainable, and versatile method used across multiple industries. Its ability to selectively extract bioactive com pounds while maintaining purity makes it a preferred choice in pharmaceuticals, food processing, cosmetics, and herbal medicine.

Supercritical CO2 extraction process has the characteristics of fast mass transfer rate, strong penetration ability, high extraction efficiency and low operating temperature. This technology has been widely used in medicine, food, chemical industry and other industries.

Supercritical fluid extraction kettle is a device used to separate components in a mixture. It is a key device in supercritical fluid extraction technology. The extraction kettle usually includes a container that can withstand high temperature and high pressure, and a stirring system to promote the mixing of reactants.
