High Purity Liquid Carbon Dioxide
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.
We offer compressed carbon dioxide gas and liquid carbon dioxide (CO2) in a variety of purities and concentrations including but not limited to beverage grade, food grade and USP.

Solid carbon dioxide(Dry Ice) is used as blasting agent and refrigerant. Solid carbon dioxide is used for cooling gas chromatography ovens.
Carbon dioxide is used extensively as a neutralizing agent for pH control,for example, in cement curing water treatment and in many other commercially important chemical applications.
A substantial volume of carbon dioxide is used for carbonating baverages such as beer and many soft drinks and conservation of wine, unfermented grape juice and various fruit juices.
Carbon dioxide is employed in medicine in mixtures with oxygen, for reanimating victims of asphyxiation (drowning, electrocution, carbon monoxide poisoning, diphtheritic toxin morphine, scopolamine). It also serves in the treatment of certain skin affections. Carbon dioxide is also used for blood analysis and dehydration of penicillin.
1.Q: Is carbon dioxide a greenhouse gas?
A: 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.
2.Q: What are the uses of carbon dioxide?
A: 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.
3.Q: What are the sources of carbon dioxide?
A: There are many sources of carbon dioxide emissions, including: combustion of fossil fuels (coal, oil, natural gas); production and processing of coal and oil; animal respiration and feces; plant respiration and humic acid fermentation; Fermentation and decay of organic matter (animals, plants); Volcanic eruptions, forest fires, etc.
