Supercritical CO2 Extraction

4 stars based on 52 reviews

Carbon Dioxide has 3 physical states of gas, liquid and solid which depend on temperature and pressure. Where does CO 2 come from? CO 2 is derived from a number of sources including combustion of carbonaceous fuels, fermentation, natural wells, and as a by-product of industrial processes such as ethylene oxide and bioethanol production and ammonia synthesis.

Supercritical co2 vs liquid co2 pumps Solid State Dry Ice: Below the triple point 5. Dry ice supercritical co2 vs liquid co2 pumps the common trade name for solid CO 2. At atmospheric pressure it has a temperature of approx. The solid CO 2 changes directly into its gaseous state. This evaporation sublimation does not leave any residues. Dry ice is non-toxic, non-inflammable, inert, without smell and bacteriostatic. It is white and has a density of approx. Dry ice is an ideal refrigerant which qualifies especially well for various applications.

It has a high cooling capacity and heat transfer is very high when in direct contact with the cold material. Within a temperature range between This means that, below 5. This is called the triple point. The critical point of CO 2 lies at a temperature of approx. Above the critical point there is no physical difference between the liquid and gaseous phase. The liquid state is important for the storage and transportation of CO 2 as well as during cooling and freezing applications.

This is associated with a high cooling supercritical co2 vs liquid co2 pumps due to the evaporation heat which is extracted from the environment when releasing the liquid CO 2. CO 2 gas has a density of approx. In all these applications it is important for the CO 2 gas to drive out and replace the atmospheric oxygen. Moreover, CO 2 gas is used for enriching the atmosphere in greenhouses, in storing fruits and vegetables and for pH control when treating potable and waste water.

CO 2 and Dry Ice Logistics other countries. From liquid CO 2 into dry ice. From liquid CO 2 into dry ice Carbon Dioxide has 3 physical states of gas, liquid and solid which depend on temperature supercritical co2 vs liquid co2 pumps pressure.

ASCO has the best range of dry ice machines for dry ice production.
