Cryogenics - Wikipedia
Liquid nitrogen is the most commonly used element in cryogenics and is legally purchasable around the world. Liquid helium is also commonly used and allows for the lowest attainable temperatures to be reached.
CRYOGENIC FLUIDS
2011年2月2日 · It is generally agreed that cryogenic fluids are those whose boiling points (bp) at atmospheric pressure are about 120 K or lower, although liquid ethylene with its boiling point of 170K is often included. A list of the cryogenic fluids, together with some selected properties, is given in Table 1.
All about cryogenic fluids: Characteristics, qualities, and applications
In this blog, we therefore look at seven commonly used cryogenic fluids. We address several unique characteristics and discuss the fluids’ role as cryogenic fuel, energy carrier or refrigerant in various industries. We also look at some of our recent …
Cryogenic Liquid - an overview | ScienceDirect Topics
2012年1月6日 · A cryogenic liquid is defined as a liquid with a normal boiling point below −130°F (−90°C). The most commonly used industrial gases that are transported, handled, and stored in the liquid state at cryogenic temperatures are …
About Cryogenics - NIST
Cryogenic liquids, such as oxygen, nitrogen, and argon, are often used in industrial and medical applications. The electrical resistance of most metals decreases as temperature decreases. Certain metals lose all electrical resistance below some transition temperature and become superconductors.
Introduce basic definitions used in describing cryogenic fluids & their properties. Describe important fluid properties and their variation with temperature and pressure. Introduce the law of corresponding states. Describe where fluid properties may be found.

A cryogenic liquid is defined as a liquid with a boiling point below -130 o F (-90 o C). Common cryogens and their properties are summarized in Table 1.
Cryogenic liquids are extremely cold liquids that at normal temperature and pres- sure would be a gas. These very cold liquids provide a fluid media that is useful for

Cryogenic liquid cylinders, sometimes also referred to as Dewars, are insulated, vacuum jacketed, pressurized vessels. They come equippmed with safety relief valves and rupture disks to alleviate pressure buildups.
About Cryogenics - NIST
2016年9月7日 · The common permanent gases referred to earlier change from gas to liquid at atmospheric pressure at the temperatures shown in Table 1, called the normal boiling point (NBP). Such liquids are known as cryogenic liquids or cryogens.
