CO2 EXTRACTION EQUIPMENT Supercritical fluid extraction is the most advanced physical extraction technology in the world, referred to as SFE (supercritical fluid extraction). At lower tem- peratures, when pressure of gas continues to increase, gas will transform into liquid. When pressure increases, volume of liquid increases. For a specific substance, there is always a critical temperature (Tc) and critical pressure (Pc), above critical temperature and critical pressure, the substance will not become liquid or gas. This is critical point. In the range above critical point, the state of substance is between gas and liquid, and the fluid within this range becomes supercritical fluid (SF). Su- percritical fluids have strong penetrating power similar to gases and large density and solubility similar to liquids. They have good solvent properties and can be used as solvents to extract and separate monomers. Supercritical fluid extraction and separation technology utilizes the fact that the dissolving ability of supercritical fluid is closely related to its density, and the density of supercritical fluid is greatly changed by changing the pressure or temperature. In the supercritical state, the supercritical fluid is brought into contact with the substance to be separated, so that it can selectively extract components with different polarity, boiling point and relative molecular mass. The process of dissolving and separating substances with supercritical fluid is called supercritical fluid extraction. There are many substances that can be used as Supercritical Fluid, such as carbon dioxide, nitrous oxide, sulfur hexafluoride, ethane, heptane, ammonia, etc. Among them, CO2 is mostly used because of the critical temperature of CO2 is close to room temperature, and CO2 is safe, colorless, non-toxic, odorless, and non-flammable, chemically inert, cheap, and easy to be produced. Supercritical co2 extraction system uses excellent solvent capability of supercritical CO2 to effectively separate, extract and purify raw material and extract. Su- percritical CO2 can quickly penetrate into solid materials and extract their essence. It is highly efficient, not easily oxidized, and Purely natural, no chemical pollution and other characteristics. CAREDDI Supercritical CO2 Extraction System is well-designed system which can let supercritical fluid CO2 flow through Extractors and Separators at stable flow speed in closed loop. The CO2 will take out the essence from the raw material continuously in the extractor, and CO2 mixed with the essence will be separated in the Separators. CAREDDI Supercritical CO2 System consists of Extractors, Separators, Cooling system with chiller, Heating exchange system, CO2 Storage tank, High pressure pump, Co-solvent pump, CO2 Recovery Compressor.
