ADVANTAGES USING CO2 IN SUPERCRITICAL STATE |
|
Characteristics of supercriticalCO2 state |
Benefits derived by the supercritical CO2specific characteristics |
| is odorless, non-toxic | does not contaminate raw material or the environment |
| is a gas in the atmosphere. Biological processes leave no trace or contamination | allows utilization of waste products as raw materials or other byproducts |
| critical temperature of the process is near to the room temperature | ability to obtain extracts without thermic alteration |
| retains its high permeability similar to a gas | the extraction time is shorter than that required by common solvent extraction |
| changing conditions of pressure and temperature also can change the solvent properties | efficient extraction and high product quality |
| is inexpensive, does not burn, does not present the risks associated with the use of organic solvents | easy to use and safe |
| CO2 industrial recycling is simple and thermodynamically neutral | cost savings for energy and solvent |
| CO2 is taken from the atmosphere and returns to the atmosphere | CO2 extraction cycles applied to industrial process do not alter the environmental balance |
| completely saturates the extraction chamber | removal of the extract from the matrix is complete, occurs in a single industrial phase and it is not subject to very rapid heating as in other technologies. Optimization of processing times. Inhibition of oxidative processes. |
| the high pressure process generates differential pressure between the inside and the outside of the cells of bacteria and microorganisms | in many cases remarkable or total reduction of bacteria is obtained |
| high flexibility. Use in many different operating conditions in industrial processes | use in extraction, fractionation, polymerization and micronization, pasteurization, purification, synthesis reactions, etc.. |
| The molecule of CO2 is not polar | He has a remarkable facility to dissolve the fat fraction like vegetable oils and waxes |
| Can be used as a carrier for its permeability to matter | Associated with water as a solvent also can extract hydrophilic substances with remarkable efficiency (such as caffeine from coffee) |
