Carbon Dioxide Recovery and Reuse

Carbon Dioxide Recovery and Reuse

♦Automotive

Carbon dioxide is present as a component in many gas mixtures, including two-, three-, and multi-component gas mixtures used in the automotive industry. In engine emissions testing, carbon dioxide in nitrogen is used as a span gas calibration mixture.

♦Food and Beverages

Air Liquide supplies carbon dioxide to customers in the food and beverage industry for a range of applications, including carbonation. Beverage-grade liquid carbon dioxide is a key ingredient in carbonated beverages such as soda, beer, and wine. The food industry uses carbon dioxide for food processing applications such as refrigeration and freezing, modified atmosphere packaging, and temperature control for storage and transportation of products.

♦Healthcare

Carbon dioxide USP is often combined with oxygen or air as a respiratory stimulant to promote deep breathing. Additionally, CO2 is used for insufflation, respiratory therapy, and pulmonary function testing.

♦Pulp and Paper

Carbon dioxide is used in the pulp and paper industry to control pH, increase pulp yield, and wash brown and bleached pulp.

♦Metal Fabrication

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

♦Oil & Gas

In the upstream oil and gas industry, carbon dioxide is used in well service applications such as hydraulic fracturing, as well as in enhanced oil recovery (EOR) applications such as miscible flooding.

♦Research & Industry

Air Liquide offers high-purity carbon dioxide as a pure specialty gas in three grades. ALPHAGAZ supercritical chromatography (SFC) grade carbon dioxide is carefully manufactured to minimize critical impurities that affect SFC performance. SFC-grade carbon dioxide has a purity of 99.995%. ALPHAGAZ supercritical fluid extraction (SFE) grade carbon dioxide has a purity of 99.997%, making it ideal for extracting components. ALPHAGAZ Grade 1 carbon dioxide has a purity of 99.99% and is designed for other laboratory applications.

♦Water Treatment

Across many industries, carbon dioxide is used in water treatment applications, such as reducing pH and neutralizing process and wastewater streams.

♦Related Supply Modes

Carbon dioxide is available in bulk, in single or multi-cartridge packages, and in liquid dewars. We offer compressed CO2 gas and liquid CO2 in a wide range of purities, concentrations, and volumes.
