CRYOGENIC FLUIDS
网页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. Detailed properties are available commercially ...
Cryogenics - Wikipedia
网页Liquefied gases, such as liquid nitrogen and liquid helium, are used in many cryogenic applications. 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.

All about cryogenic fluids: Characteristics, qualities, and applications
网页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 projects in which the seven fluids were central.

网页Cryogenic Liquid Cylinders. 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. These cylinders come in a variety of sizes ranging from 80-450 liters.
Cryogenic liquids: what they are, how they are obtained.
网页2021年12月10日 — What are cryogenic liquids and how are they obtained? Cryogenic liquids are gases that have been intensely cooled, which have a boiling point close to -100º or lower. These gases must be cooled below ambient temperature.
