Factors affecting the supercritical CO2 extraction of vegetable oils-Cosolvent & CO2 flow

The solubility of grease in supercritical CO2 fluid is generally low. In order to improve the solubility, you can consider adding a co-solvent.

Therefore, the CO2 flow rate has an optimal value in extraction. Generally, when the oil content of the raw material is high, the large CO2 flow rate is beneficial to the extraction. But in fact, CO2 flow is not easy to control during operation.
