The role of gas booster pump in critical extraction of carbon dioxide

According to the unique properties of carbon dioxide, after being pressurized by a gas booster pump to a certain pressure, carbon dioxide will enter the critical state. For some customers, the supercritical pressure of carbon dioxide may require high pressure at normal temperatures, so a dedicated carbon dioxide booster system will be used.

Carbon dioxide critical extraction is a process that utilizes the relationship between the solubility and density of supercritical fluids, and the influence of pressure and temperature on the solubility of the boundary fluid. In a supercritical state, the critical fluid is brought into contact with the substance to be separated, selectively extracting the components of polarity, boiling point, and molecular weight in sequence.   

The carbon dioxide reaction in the critical state has significant advantages. (1) Better activity: Critical carbon dioxide extraction technology is used for extraction near room temperature and under the cover of carbon dioxide gas, effectively preventing the oxidation and escape of thermosensitive substances, and maintaining the purity and active ingredients of the original liquid and essential oil; (2) Higher purity: Combining extraction and separation into one, when the carbon dioxide fluid containing dissolved substances flows through the separator, the pressure drop causes rapid gas-liquid separation between the carbon dioxide and the extract, resulting in high extraction efficiency and high purity of the extract; (3) Higher performance: Carbon dioxide is an inert gas that does not undergo chemical reactions during the extraction process. It is also a non flammable gas, odorless, and has good performance; Compared to traditional extraction methods, critical carbon dioxide extraction does not contain residual enzymes, nitrates, or harmful solvents such as heavy metals, which prevents the extraction process from harming human health and polluting the environment; (4) Higher environmental friendliness: Carbon dioxide has high purity, is easy to obtain, and can be recycled during the production process, which is beneficial for environmental protection; And completely extract substances with different boiling points, volatility, and pyrolysis.
