Supercritical State Creation
CO2 becomes supercritical when its temperature and pressure exceed the critical values ( and ). The extractor uses a high - pressure pump and a heater to get CO2 into the supercritical state (usually 30 - 50MPa in pressure and proper temperature).
Extraction
The material for extraction is put in the extraction vessel. Supercritical CO2 is pumped into it. With good fluidity and diffusivity, it gets into the material. It can dissolve target substances. The solubility depends on the density of CO2 which is affected by temperature and pressure. The process continues until equilibrium, and a stirrer (if available) can speed it up.
Separation
In the separation vessel, the solutes are separated from the supercritical CO2 by changing the pressure or temperature to reduce the solubility of CO2. The solutes are then deposited, and CO2 is recycled. One - step or multi - step separation can be used to improve the purity of the extract.
CO2 Recycling
The CO2 from the separation vessel is recycled through a cooling and compression system. It's filtered, pressurized again, and sent back to the extraction vessel for reuse, which is cost - effective and environment - friendly.
Process Control and Monitoring
The extractor has a control system to adjust and monitor key parameters like pressure, temperature, and flow rate. There are also safety - monitoring devices such as over - pressure alarms and relief valves to ensure safe and efficient operation.
LAB SCALE MODEL 10L(5LX2）
This model is very popular among new - established enterprises with small production capacity.
It has two extraction kettles with a capacity of 5L each.
The two kettles work in sequence, and after each extraction, the excess carbon dioxide in the extraction kettles can be transferred to the other kettle, thus greatly saving carbon dioxide.
