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 1.5x heavier than air but only .03% of the air we breath, 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 unique gas as in which it can exist in three states of matter, a solid, a liquid or a gas.
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.
Liquid CO2 for Food Freezing
High pressure liquid CO2 can be sprayed onto food products including poultry, meats, vegetables, fruit and pizzas to flash freeze the product during preparation and packaging.
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.
- Fire suppression – CO2 does not burn or support combustion, and air with more than 10% of carbon dioxide will extinguish an open flame.
- Plant cultivation and greenhouse gassing and supercritical extraction.
- Waste water treatment and Ph control
Carbon Dioxide Cylinder Options
CO2 is filled and classified by weight full as it remains in liquid form inside the cylinder. Cylinders can be ordered with a ‘siphon’ or ‘dip-tube’ to withdraw liquid directly from the valve or standard which naturally pulls gas from the headspace or vapor portion of the cylinder. Full tanks will have between 850-900 psi when full depending on temperature. Cee Kay Supply can provide exchange cylinders from 5lbs for beer kegerators, paintball or aquariums up to 50 ton bulk tanks for large scale manufacturing. Liquid CO2 Dewar type cylinders are available which can supply liquid or gas out of the same cylinder depending on requirements.
Be sure to review the carbon dioxide chart and information sheet for more information regarding all C02 specifications.
