Function of Supercritical CO2 Pump in Supercritical Extraction

supercritical carbon dioxide CO2 extraction. It is based on the relationship between the solubility of supercritical fluid and its density, that is, the influence of pressure and temperature on the solubility of supercritical fluid. In the supercritical state, the supercritical fluid is contacted with the material to be separated, so that it can selectively extract the components of polarity, boiling point and molecular weight in turn.

The extraction of supercritical carbon dioxide CO2 corresponding to each pressure range can not be single, but the optimum proportion of the mixture can be obtained under the control conditions. Then the supercritical fluid becomes a common gas by increasing pressure and increasing temperature, and the extracted substance is completely or basically precipitated, so the supercritical carbon dioxide CO2 fluid extraction process is composed of extraction and separation process.

Characteristics of supercritical carbon dioxide CO2 extraction determine its wide application range. For example, in the pharmaceutical industry, it can be used for the extraction of active ingredients of Chinese herbal medicine, the refining of thermosensitive biological products, and the separation of lipid mixtures; in the food industry, the extraction of hops and pigments; in the spice industry, Natural and synthetic spices refining; chemical industry mixture separation, etc.

Supercritical carbon dioxide CO2 extraction equipment uses carbon dioxide special booster pump as the core element, can pressurize the carbon dioxide   between 0-110 MPA, suitable for all kinds of temperature and occasions, customer site necessary condition 1: pure carbon dioxide gas. The clean compressed air flow bar 2:3-8 is above 800 L/min. 3： tooling for connecting equipment. A container or reactor 4： carbon dioxide.
