CO₂

Carbon Dioxide

Carbon dioxide is a colorless, odorless, tasteless and non-toxic gas. Melting point -56.6°C (0.52MPa), boiling point -78.6°C (sublimation), density 1.977g/L.

Carbon dioxide has a wide range of industrial uses.

Dry ice can be obtained by liquefying carbon dioxide into a colorless liquid under a certain pressure, and then rapidly solidifying under low pressure. Its temperature is minus 78.5 ℃. Because of its very low temperature, dry ice is often used to keep objects frozen or cryogenic.

Process

Carbon dioxide is recovered from many different sources. It is obtained as an off-gas from fermentation processes, lime-stone kilns, natural CO2 springs, as well as gas streams from chemical and petrochemical operations. Recently, CO2 is also recaptured from the off-gas from power plants.

Applications

Agricultural

Carbon dioxide is used to modify atmospheres, for example in green houses where it increases plant growth rates or combined with nitrogen to prolong quality in food packaging applications(MAP).

Industrial

Carbon dioxide is used as an inerting agent for various mild steel welding operations, often in combination with argon.

Dry Ice

Solid carbon dioxide(Dry Ice) is used as blasting agent and refrigerant. Solid carbon dioxide is used for cooling gas chromatography ovens.

Liquid CO2

Liquid carbon dioxide is becoming increasingly used as a refrigerant in mechanical refrigerating systems due to its environmental credentials.

Environmental

Carbon dioxide is used in mixtures for car emission monitoring and environmental monitoring. Carbon dioxide is used for fire extinguishing.

Frequently Asked Question

What’s the specification can you supply?

What is the molar mass of carbon dioxide？

The molecular mass of carbon dioxide is 44.01amu.

What is carbon dioxide chemical formula?

CO2

What are the uses of carbon dioxide?

High-purity carbon dioxide is mainly used in the electronics industry, medical research and clinical diagnosis; gaseous carbon dioxide is used for carbonated beverage addition, pH control, chemical processing, welding gas; solid carbon dioxide (dry ice) is widely used in food refrigeration, etc.

Is carbon dioxide a greenhouse gas?

Yes. Greenhouse gases refer to some gases in the atmosphere that absorb solar radiation reflected from the ground and re-emit the radiation, such as water vapor, carbon dioxide, most refrigerants, etc. They warm the earth’s surface and heat the air in the greenhouse.

What are the sources of carbon dioxide?

There are many sources of carbon dioxide emissions, including: ① combustion of fossil fuels (coal, oil, natural gas); ② production and processing of coal and oil; ③ animal respiration and feces; ④ plant respiration and humic acid fermentation; ⑤ Fermentation and decay of organic matter (animals, plants); ⑥ Volcanic eruptions, forest fires, etc.
