Carbon dioxide (CO2) is used as a key cryogenic agent in cooling, chilling and freezing applications — protecting the taste and texture of your food products by maintaining proper temperature control. CO2 also reduces the need for preservatives in packaged products, and is an essential ingredient in carbonated beverages.
Flour & Dough Cooling
Freezing & Chilling
Carbon dioxide USP is used for insufflation and is often combined with oxygen or air as a respiratory stimulant to promote deep breathing.
Respiratory Therapy & Pulmonary Function Testing
It is well known in the oil industry that carbon dioxide can be applied to your reservoir as a tertiary oil recovery method. At Praxair, we can provide CO2 injectivity testing, pilot applications and full-field projects. We also provide CO2 services for energized fluid fracturing (fracing) in conventional reservoirs for both long-reach horizontal and vertical wells.
Enhanced Oil Recovery
Well Hydraulic Fracturing
Carbon dioxide is an industrial gas used in the pulp and paper industry to control pH levels, enhance pulp yield, and wash brownstock and bleached stock.
A safe alternative to mineral acids, carbon dioxide replaces chemicals used in pH reduction — lowering costs and improving plant safety and flexibility.
Carbon dioxide is most often mixed with argon as a shielding gas used to prevent atmospheric contamination of molten metal in electric arc welding processes.
