Supercritical CO2 property

ADVANTAGES USING  CO2  IN SUPERCRITICAL STATE

Characteristics of supercritical 
CO2 state
Benefits derived by the supercritical CO2 
specific 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)
