Supercritical CO2 Extraction Equipment Descriptions

The plant of 600L×3 is three extractor two separator SCFE device, the working medium is CO2, which can be reused. The extract, separate pressure and temperature can be automatic and remote controlled by computer. The extractors can work with the way of series, parallel and single. The series valves on the import and export of each extractor can be manual controlled, the highest working pressure control method of each extractor during working is by the use of pressure transmitter, safety valve and control signals. It is safety and reliable. The extractor cover of this plant uses hydraulic pressure quick opening structure. The metal contact with material of this plant, such as container inner surface, pipe, valve and so on. All of them are manufactured with stainless steel which has the characters of anti-sour and anti-alkali and satisfy food hygiene demand.

Supercritical CO2 Extraction Equipment

Supercritical CO2 Extraction Equipment Characteristic

1. Low viscosity and high air permeability;

2. Excellent solubility with similar liquid density;

3. The solubility of a substance depends on the density of the solvent. By changing the pressure and the temperature, we can achieve a change in the solubility parameter;

4. CO2 gas is easy to get, cheap, can be recycled in production ;

5. NO Solvent residue;

6. By changing the pressure and temperature, we can achieve changes in solubility;

7. The extraction takes place at low temperatures and the material will not be destroyed;

8. Wide selection (solubility controllable);

9. The separation is simple and efficient without any residue;

10. Ecological safety, does not affect the environment.

Supercritical CO2 Extraction Equipment Composition

The equipment is composed of CO2 supply system, extraction and separation system, CO2 circulation system, clean system, co-solvent system, cold water circulation system, hot water circulation system, steel platform, control system, tail gas recovery system, and so on.

The control system is composed of low voltage switch box, PLC control cabinet, extractor quick-open chain control cabinet, control computer, cooling unit control cabinet, and so on. The low voltage switch box contains breaker, contactor, thermorelay, transducer, PLC cabinet contains PLC module, intermediate relay, DC24V power supply, the following is PLC control picture.
