Becoming Familiar With Supercritical CO2 Extraction
CO2 extraction technology permits a process which removes specific compounds. With minimal pressure and low-heat
technology, specific systems consume significantly less energy, are
much less invasive to a targeted compound, and can give you a greater roi.
Supercritical CO2 is now an essential commercial as
well as industrial solvent due to its role in chemical extraction in
addition to its minimal toxicity not to mention environmental
influence. The reasonably low temperature of the process and the stability of CO2 likewise enables most compounds to get extracted with almost no damage or denaturing. In addition, the solubility of many extracted compounds in CO2 vary with pressure, permitting selective extractions.
Co2 is increasing in popularity among coffee manufacturers wanting to move away from a number of the classic decaffeinating chemicals of the past, a few of which result in public outcry due to real or perceived hazards linked to their use in preparing food. Supercritical CO2 is forced through the green coffee beans and then they are sprayed with standard water at high pressure to remove the caffeine. The caffeine may then be separated for resale (e.g. to the pharmaceutical industry or to beverage companies) by moving the water thru activated charcoal filters or possibly by distillation, crystallization or reverse osmosis.
Supercritical co2 may also be used as a more
eco-friendly solvent for dry cleaning as compared to more traditional solvents such as hydrocarbons as well as
Supercritical co2 is utilized as the extraction solvent for the
production of essential oils and other natural and organic distillates. Cool Clean's essential oils removal processes using CO2 extraction technology is great for removing precious compounds from a variety of feedstocks, like scents from flower blossoms, extracts from fruit or bark as flavorants, extracts from numerous sources for the purpose of medical, pharmaceutical requirements or as food preservatives.
CO2's main advantages over chemicals such as
hexane as well as acetone during this process are that it is non-toxic not to mention non-flammable. Additionally, separation of the reaction components from the commencing material is much simpler than with standard organic solvents, just by allowing it to evaporate directly into the air recycling it by condensation into a ice cold recovery vessel. Its actual advantage over steam distillation is it is used at a lower temperature, which can isolate the plant waxes from the oils.
Techniques which use supercritical carbon dioxide to deliver micro and nano scale particles, typically for pharmaceutical applications, are currently truly being developed. The gas antisolvent method, rapid expansion of supercritical solutions, and supercritical antisolvent precipitation (along with numerous affiliated
approaches) have been shown to process several different
substances straight into particles.
Many in the industry understand extraction of compounds
applying supercritical CO2 extraction techniques. Cool Clean Technologies offers this capability, but their
concentration of technological know-how implements the utilization of liquid CO2 (LCO2) for extraction-which is much more cost-effective when compared with
Cool Clean Technologies possesses the ability to extract compounds applying supercritical CO2 extraction methods, however their focus of technology incorporates the use of liquid CO2 (LCO2)
for the purpose of extraction-which is much more cost-effective when compared with supercritical CO2 extraction.
