Use of carbon dioxide (CO 2 ) gas and liquid carbon dioxide in various industries

food and drink

Carbon dioxide (CO 2 ) is an important refrigerant for cooling, refrigeration and freezing. It protects food taste and texture through proper temperature control. Carbon dioxide also reduces the need for preservatives in packaged products and is a basic ingredient of carbonated beverages.

medical insurance

Carbon dioxide USP is used for gas injection operations and is usually used in combination with oxygen or air as a breathing stimulant to promote deep breathing.

Petroleum gas

It is well known that carbon dioxide can be used in the tertiary oil recovery process in the petroleum industry. Praxair offers CO2 injection testing, pilot production and full field projects. We also provide live fluid fracturing carbon dioxide services for long and horizontal wells in conventional reservoirs.

Pulp and paper

As an industrial gas, carbon dioxide can be used in the pulp and paper industry to control pH levels, increase pulp yield, and clean unbleached and bleached pulp.

Water and wastewater treatment

Carbon dioxide can be used as a safe alternative to inorganic acids to lower pH, reduce costs, and increase equipment safety and flexibility.

Welding and metal processing

Carbon dioxide is often mixed with argon to form a protective gas, which prevents the molten metal from being polluted by air during the arc welding process.
