Carbon dioxide (CO2) serves a variety of key applications across industries. In its solid state (-78°C), known as dry ice, is used as a cryogenic fluid for processes such as tissue conservation deep-freezing and fire extinction due to its non-combustible nature. CO2 that is emitted into the atmosphere by chemical and oil and gas operations can be captured and purified for use in many industries and applications.
Air Liquide supplies CO2to customers in the food and beverage industries for a range of applications. Food-grade 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 and temperature control for products that are being stored and transported.
