UPGRADING THE RECOVERED CO 2 2 2 The concentration of CO in atmospheric air is very low (0.04%). CO is one of the gases sold by Air Liquide around the world. It is recovered from industrial facilities such as fertilizer or bioethanol plants, which emit it during their own processes. 2 The market for CO is a relatively tight one. With the Cryocap™ installation in Port-Jérôme, Air Liquide strengthens and secures its production capacities, as well as improving its ability to satisfy demand. The main applications of CO 2 The agri-food industry: carbonation, Other industries 2 preservation, and refrigerated transport CO is slightly acidic, which makes it suitable for use in water 2 treatment to control pH content and neutralize effluents. It In the form of snow or ice, CO constitutes an extremely powerful and practical source of cold that has a variety can also be used to remineralize drinking water. of uses in the production and shipment of food products, for example to preserve in-flight meals served onboard airplanes In addition, it can be used as a chemical reagent to extract at the correct temperature. the molecules from certain oil and gas products or even for cryogenic cleaning, because it leaves no trace or residue. In its gaseous form, it extends the shelf life of certain 2 2 CO is also present in the composition of certain shielding products by replacing the air in packaging with CO , alone or combined with nitrogen. This helps to cut down on food gases used in welding. waste. It is also used in sparkling beverages, for which Lastly, it can be used to produce theatrical smoke and fog it provides the bubbles, as well as for beverages served in or for other forms of entertainment. restaurants on tap. Used in greenhouse growing, it helps to speed up the process of photosynthesis and improve crop yields.
