Carbon Dioxide (CO2) is one of the most abundant chemicals found in nature. It is found in the atmosphere, dissolved in water, used by plants to form food by photosynthesis, and expelled from vehicles as a byproduct of combustion. It is slightly toxic, odorless, colorless, and in large quantities has a slightly acidic taste. Producing carbon dioxide as an industrial product requires that it be recovered and purified from a relatively high-volume, CO2-rich gas stream, generally a stream created as an unavoidable byproduct of a large-scale chemical production process or some form of biological process.
CO2 is a critical gas for many industrial and commercial uses, but its presence in the atmosphere is increasing every year. In fact, its status as a greenhouse gas has raised concern over CO2 and its role in global warming.
The Industrial Uses of CO2
Carbon dioxide is a common and versatile chemical that has many business uses. All of these uses take advantage of one or more of the major characteristics of this gas: inertness, reactivity, or its low freezing point.
CO2 is used on a large scale as a shield gas for MIG/MAG welding, where the gas is used to protect the weld puddle against oxidation caused by the surrounding air. A mixture of argon and carbon dioxide is used to reduce the need for post-weld treatments.
Dry Ice for Quick Refrigeration
High pressure liquid CO2 can be sprayed onto food products to flash freeze them through the process of sublimation, in which a solid goes directly to a gas state.
Carbon dioxide is used to maintain pressure in oil wells for oil extraction. When CO2 is pumped into an oil well, it is partially dissolved into the oil, making it less viscous and easier to recover.
Other Commercial Uses of Carbon Dioxide
- As a propellant in aerosol cans to replace less environmentally friendly alternatives.
- To carbonate soft drinks, beer, and sparkling wine, and as an agent to prevent bacterial and fungal growth in beverages.
- To displace air in the canning process.
- Dry ice pellets are used instead of sand when sandblasting paint from surfaces to reduce the cost of cleanup.
- CO2 does not burn or support combustion, and air with more than 10% of carbon dioxide will extinguish an open flame.
