CO2 Gas Pressurisation Unit

Carbon dioxide booster pump in the supercritical extraction test plays an important role in the above

Carbon dioxide extraction process is actually carbon dioxide separation process, is the use of supercritical state of carbon dioxide on some substances have a special dissolution process, the use of supercritical carbon dioxide volumetric capacity and his density, that is, with the pressure and temperature on the carbon dioxide volumetric capacity of the impact and carry out;

Supercritical extraction booster device is generally a set of booster devices composed of FIENTE pneumatic carbon dioxide booster pump as the core plus valves and pressure gauges, etc., the internal components of the gas-driven CO2 booster pump sealing material requirements of wear-resistant low-temperature materials, piping requirements for thermal insulation, check valves using a large diameter type of assembly, placing the icing caused by the pressure can not be upgraded or not pressurised. Usually carbon dioxide extraction is carried out using the extraction function.

Simply put, the carbon dioxide medium is pressurised to a very high level (3 miles below sea level, 200 times atmospheric pressure) so that the high pressure gas is able to dissolve the aromatic oils in the plant. When the pressure is lowered (to 100 times atmospheric pressure), the carbon dioxide changes from a liquid to a gaseous state, so that the essential oils, which are still in a liquid mist, can be separated and collected. Compared with solvent extraction, this extraction method does not leave any solvent residue.
