What Is Supercritical Fluid Co2 Extraction Equipment?
The principle of supercritical fluid CO2 extraction equipment and separation process is that supercritical CO2 has a special dissolving effect on some special natural products, and the relationship between the dissolving ability of supercritical CO2 and its density, that is, the influence of pressure and temperature on the dissolving ability of supercritical CO2.
Supercritical fluid CO2 extraction equipment technical principle
The principle of supercritical fluid CO2 extraction equipment and separation process is that supercritical CO2 has a special dissolving effect on some special natural products, and the relationship between the dissolving ability of supercritical CO2 and its density, that is, the influence of pressure and temperature on the dissolving ability of supercritical CO2. In the supercritical state, the supercritical CO2 is contacted with the substance to be separated, so that it can selectively extract the components with different polarity, boiling point and molecular weight. Of course, the extracts obtained in the corresponding pressure range can not be single, but the optimum proportion of the mixture can be obtained by controlling the conditions. Then the supercritical fluid can be transformed into ordinary gas by means of decompression and heating, and the extracted material can be completely or basically precipitated, so as to achieve the purpose of separation and purification. The extraction of CO2 from the boundary fluid is a combination of extraction and separation.
Extraction device
Supercritical extraction devices can be divided into two types, one is research and analysis, mainly used in the analysis of small amounts of substances, or provide data for production. The two is the production of production, mainly for mass production or mass production.
Supercritical extraction unit can be divided into eight parts: extractant supply system, low temperature system, high pressure system, extraction system, separation system, modifier supply system, circulation system and computer control system. Specifically including CO2 injection pump, extractor, separator, compressor, CO2 tank, chiller and other equipment. Because the extraction process is carried out under high pressure, the pressure resistance of the equipment and the whole pipeline system is required to be high. The automatic monitoring of the production process by microcomputer can greatly improve the safety and reliability of the system and reduce the operation cost.
