Solvent-Free Critical Cleaning

Clean the smallest crevices of implants and completely clean devices without leaving residue behind. Using supercritical CO₂ allows you to employ its properties to great benefit:

No surface tension
Carbon Dioxide in its supercritical state has the permeability to reach into the smallest crevices of any implant. Unlike liquids, Supercritical CO₂ has no surface tension that would prevent it from reaching all of the crevices and completely cleaning the device. Supercritical CO₂ goes deeply into the smallest interstices, and solubilizes impurities, such as paraffin and other binders or lubricants used in the production of the implant.


No residue
Supercritical CO₂ does not leave any residue on the implant. CO₂ simply evaporates back into the atmosphere, leaving behind no contamination. Unlike solvents there is no residue and no clean-up.

Clean Extraction of Essential Oils – Flavors and Fragrances

The use of essential oils has become "essential" for modern living. Essential oils can be primary ingredients in perfumes for cosmetics or soaps and detergents. They form the basis of the spices in our foods. Using supercritical fluids to extract the essential oils is more efficient and leaves no solvent residue!

Find out how to extract essential oils and keep them in their natural state.

Environmentally Friendly Textile Dyeing

The conventional dyeing of textiles requires that an excess of dye is dissolved or in some way "taken-up" in an aqueous or solvent solution. The dye mix is then pumped into a vat containing holding the textile. Typically there is agitation or the dye is recirculated several times through the cloth. At the end of the cycle, the dye mix is pumped to the waste treatment facility. Dyes are notoriously difficult to treat. The process is decidedly unfriendly to the environment.

The use of supercritical CO₂ in textile dyeing is an environmentally friendly alternative.

Decaffeination of Coffee with Supercritical Fluids

The blog, "Espresso Coffee Maker" has recently featured a post on "The Process of Coffee Decaffeination" which features the use of supercritical fluids as "an excellent agent for separating an element such as caffeine from a coffee bean..."

The Applied Separations website has more information about the supercritical fluid extraction process.

"Green" Process for the Extraction of Natural Products

The term natural products has become the "catch-all" for any compound that has been produced by a living being, e.g. plant, animal, algae. The extracted compounds are used in, or are themselves, foods, medicinals, pigments, fragrances. The process for many years was to extract from the matrix material by solvents: aqueous and petroleum based. The first large scale use of supercritical fluids in extracting natural products was the decaffeination of coffee in 1979 and since then thousands of compounds have been extracted commercially.

Growing environmental concerns have renewed interest supercritical fluids as the “green” alternative for natural products extractions. Find out how “green” your process.
