Carbon Dioxide

Anticipating the needs of the industry

Carbon dioxide is used as a cryogenic fluid for processes such as tissue preservation, deep freezing, and fire fighting due to its non-combustible nature.

Carbon dioxide (CO2) is useful for a variety of key applications across industries. In the solid state (-78 ºC), carbon dioxide is also known as dry ice, it is a cold source that can be used as a cryogenic fluid for processes such as tissue preservation by freezing and fire extinction, since it is not fuel. Carbon dioxide released into the atmosphere by oil and chemical industry operations can be captured and purified for use in many industries and applications.

In the automotive industry, the carbon dioxide in nitrogen is used as a trim gas in calibration gas mixtures, which are used in engine emissions testing.

Air Liquide supplies carbon dioxide to customers in the food and beverage industry for use in a wide range of applications, such as carbonation. Beverage-grade liquid carbon dioxide is a key ingredient in carbonated beverages such as soft drinks, beer and wine. The food industry uses carbon dioxide for food processing applications such as cooling and freezing, modified atmosphere packaging, and temperature control for products that must be stored and transported.
