Carbon dioxide is a colourless gas having a faint sharp odour and a sour taste. Carbon dioxide is commonly used as a raw material for the production of various chemicals. Multi industry uses for carbon dioxide in solid and in liquid form are used for refrigeration and cooling. It is used as an inert gas in chemical processes, in the storage of carbon powder and in fire extinguishers. In the metals industry, carbon dioxide is used in the manufacture of casting moulds to enhance their hardness. It is also used in the manufacturing and construction sectors on a large scale as a shield gas, where the gas protects the weld puddle against oxidation by the surrounding air. A mixture of argon and carbon dioxide is commonly used today to achieve a higher welding rate and reduce the need for post weld treatment.
Large quantities of carbon dioxide are used as a raw material in the chemical process industry, especially for methanol and urea production. It is also used in oil wells for oil extraction and to maintain pressure within a formation. When CO2 is pumped into an oil well, it is partially dissolved into the oil, rendering it less viscous, allowing the oil to be extracted more easily from the bedrock. Considerably more oil can be extracted from through this process.
In the food and beverage industry carbon dioxide is used as a liquid or solid gas for quick freezing, surface freezing, chilling and refrigeration in the transport of foods. It is also used to carbonate soft drinks, beers and wine and to prevent fungal and bacterial growth. In the healthcare industry carbon dioxide is used as an additive to oxygen for medical use as a respiration stimulant. Lastly, environmentally, it is used as a propellant in aerosol cans, it replaces more environmentally troublesome alternatives.
