Liquid Carbon Dioxide
Liquid carbon dioxide (CO2) is a colorless fluid that is created by compressing and
cooling carbon dioxide gas.
Food storage and transportation: Liquid CO2 is used to keep food at a consistent
temperature.
Decaffeinating coffee: Liquid CO2 is a solvent that can be used to remove caffeine
from
coffee.
Fire extinguishers: Liquid CO2 is non-flammable and can be used to put out Class B
and C
fires.
Entertainment: Liquid CO2 is used to create special effects in the entertainment
industry.
Industrial processes: Liquid CO2 can be used to improve the yield of olive oil
production.
Carbonation of beverages: Liquid CO2 can be used to carbonate beverages.
Water treatment: Liquid CO2 can be used for water treatment.
Testing: Liquid CO2 can be used to test aviation and electronic components at low
temperatures.
Oil and gas well stimulations: Liquid CO2 can be used to stimulate oil and gas
wells.
Chemical reactions: Liquid CO2 can be used to control chemical reactions.
Carbon dioxide can exist in three states: solid, liquid, and gas. It can be liquefied
under pressure if its temperature is below 31°C (87.8°F), which is known as the critical
point

Applications / Uses :
Liquid carbon dioxide has many applications, including:
Liquid carbon dioxide can only exist at a pressure above 5.1 atm, under 31.1 °C and
above −56.6 °C.
Food and beverage:
Used to carbonate beverages, de-caffeinate coffee, keep food
cold, and quick-freeze
Entertainment:
Used to create special effects like fog and haze
