Carbon dioxide is recovered from various sources, as a gaseous by-product from fermentation processes, lime kilns and natural sources of carbon dioxide, as well as gas emissions from chemical processes. Recently, carbon dioxide is taken from power plants as a gaseous byproduct.
Applications of carbon dioxide CO2 gas:
Carbon dioxide is widely used as a neutralizing agent for pH control. For example, in cement curing water treatment and in many other important commercial applications.
Carbon dioxide is used in many synthetic products, including gas-air mixture packages for air weapons that require pressurized gas, because it is cheap and non-flammable. It is also used in the operation of pneumatic equipment and for the transfer of dangerous and flammable condensates.
Considering that it has an effect on the nervous system, in medicine, a mixture of carbon dioxide and oxygen is used to revive victims who have suffocated. It is also used in the treatment of some skin infections.
A significant amount of carbon dioxide is used in the world for beverages such as beer, many soft drinks, wine preservation, unfermented grape juice, and a variety of juices.
Carbon dioxide is used to improve atmospheric conditions. For example, in greenhouses, it will increase the growth rate of plants in greenhouses, and in combination with nitrogen, it will increase the quality of products in food packaging.
A mixture of carbon dioxide, helium and nitrogen is used as an active medium in carbon dioxide lasers.
Carbon dioxide is used as a neutral agent for various mild steel welding operations in combination with argon.
Liquid carbon dioxide is increasingly used as a suitable refrigerant in mechanical refrigeration systems.
Liquid or solid carbon dioxide is used to cool the ovens of the gas chromatograph.
Carbon dioxide CO2 gas is used in the following cases:
For silicon dioxide chemical vapor deposition
For firefighting foam
In Coleman nitrogen analysis
in gas mixtures to monitor the pollutants released from vehicles and the environment
To put out the fire
Often in combination with ethylene oxide for the purpose of sterilization
For blood analysis and penicillin dehydration
For the production of paints and resins
Note) Carbon dioxide is mentioned in the Kyoto Protocol, an international contractual framework aimed at reducing greenhouse gas emissions.
