Liquid Argon Gas
Liquid argon is a cryogenic liquid.
Cryogenic liquids are liquefied gases with a standard boiling point below –130°F (–90°C).
Liquid argon has a boiling point of –303°F (–186°C).
The temperature difference between the product and the surrounding environment, even in winter, is substantial. Keeping this surrounding heat from the product requires special equipment to store and handle cryogenic liquids.
Air separation plants produce argon through the continuous cryogenic distillation of atmospheric air. The cryogenic liquid is recovered from the argon.
DSW provides high-quality liquid argon tanks or cylinders for cryogenic storage of liquid gases, including argon, carbon dioxide, nitrogen, oxygen, and helium.
The tanks range in capacity from 3,000 to > 100,000 liters and have standardized working pressures of 18, 22, or 36 bar, respectively.
The 20-foot ISO framework-type tank container applies to Intermodal transportation, including marine, highway, and railroad transportation. With its overall dimensions conforming to the ISO standards, the tank container has a rating for as high as nine high stacking loaded.
A typical system comprises a cryogenic tank, one or several vaporizers, and the necessary piping for filling and vaporizing. In principle, the liquid argon tank looks like a vacuum container. The cryogenic tank is designed to keep the heat from the inner vessel’s liquids. Vaporizers change liquid argon into gaseous form. A pressure control manifold can control the gas pressure fed into the process.

Argon may be referred to as “PLAR” (pure liquid argon) or “CLAR” (crude liquid argon) or by its chemical designation, “Ar.” Crude argon is usually considered an intermediate product in a pure argon facility. Still, it may be a final product for some lower-capacity air separation plants that ship it to more extensive facilities for final purification. Some crude argon is also sold as a final product for uses that do not need high-purity oxygen (e.g., some steelmaking and welding applications).
