The choice of ,supercritical CO 2, is due to its moderate critical conditions (31.1 °C and 73.8 MPa), absence of toxicity, and chemical stability. Some of the advantages of ,supercritical fluid, extraction are: solvating powers similar to liquid organic solvents, high solute diffusivities, lower viscosity, and lower surface tension; and the possibility of adjusting the solvating power by changing pressure or …

This means that oil can be delivered to interstitial spaces previously inaccessible to water jets. The oil-in-CO 2 dispersion can be sprayed out of a nozzle at high speed to deliver the oil and form dry ice in the cutting zone, as shown in FIG. 2B. The rapid expansion of the CO 2 leads to cooling at cryogenic

Extraction of Astaxantine and Phycocyanine from Microalgae ...

Astaxantine from the microalga Haematococcus pluvialis and phycocyanine from the microalga Spirulina maxima have been obtained by ,supercritical, extraction using carbon dioxide. Prior to extraction, the samples of microalgae were crushed by ,cutting, mills (coffee mill) and then manually ground with dry ice (solid carbon dioxide).
