Air Liquide supplies liquid and gaseous nitrogen to every industry. For example, refineries and petrochemical plants require large volumes of gaseous nitrogen to purge oxygen and moisture in blanketing operations. The food and beverage industry requires varying quantities of both liquid and gaseous nitrogen for food processing and packaging applications and to help maintain safe temperatures as food products are stored and transported.
Nitrogen is used as a protective/inert atmosphere for a large number of industrial processes. It’s also used in heat treatment of various metals.
In laboratories nitrogen is used as a carrier gas in gas chromatography for various industrial and hospital analyses and quality control. In many industries, nitrogen is used in smaller quantities to zero and purge analytical instrumentation.
Nitrogen is also used for low-temperature preservation of living tissues and cells.
Please consult Air Liquide's Gas Encyclopedia, available in English and French, allowing users to quickly access a host of information on the physical and chemical properties of gas molecules, indicating the material compatibilities of various gases and describing their main industrial applications.
