Carbon Dioxide

Anticipating industry’s diverse needs

Carbon Dioxide

Industrial carbon dioxide (CO2) serves a variety of key applications across industries. In its solid state (-78°C), carbon dioxide – also known as dry ice – is a cold source that can be used as a cryogenic fluid for processes such as tissue conservation deep-freezing and fire extinction, as it is non-combustible. Carbon dioxide emitted into the atmosphere by chemical and oil and gas operations can be captured and purified for use in many industries and applications.

Food and Beverage

Air Liquide supplies carbon dioxide to customers in the food and beverage industries for a range of applications, including carbonation. Beverage-grade liquid carbon dioxide is a key ingredient in carbonated beverages such as sodas, beer and wine. The food industry employs carbon dioxide for food processing applications such as chilling and freezing, modified atmosphere packaging (MAP) and temperature control for products being stored and transported. Air Liquide's carbon dioxide production facilities serving the food and beverage industry have achieved the Food Safety System Certification 22000 (FSSC 22000), an internationally recognised standard for food safety.

Metal Fabrication

In the metal fabrication industry, industrial carbon dioxide is widely used as a shielding gas in the semi-automatic welding process.

Water Treatment

In many industries, industrial carbon dioxide is used for water treatment applications such as pH reduction to neutralise process and waste water streams.

Oil and Gas

In the upstream oil and gas industry, industrial carbon dioxide is used in well service applications such as hydraulic fracturing and in Enhanced Oil Recovery (EOR) applications, such as miscible oil displacement.
