Carbon Dioxide
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.
