What is considered a permanent gas?
A gas, such as oxygen or nitrogen, that was formerly thought to be impossible to liquefy. A permanent gas is now regarded as one that cannot be liquefied by pressure alone at normal temperatures (i.e. a gas that has a critical temperature below room temperature). From: permanent gas in A Dictionary of Chemistry »
How do you liquify permanent gas?
In general, gases can be liquefied by one of three methods: (1) by compressing the gas at temperatures less than its critical temperature; (2) by making the gas do some kind of work against an external force, which causes the gas to lose energy and change to the liquid state; and (3) by making gas do work against its …
How do they liquify air?
Air is fed at high pressure (>75 atm (7,600 kPa; 1,100 psi)) into the lower column, in which it is separated into pure nitrogen and oxygen-rich liquid. Air can also be liquefied by Claude’s process, which combines cooling by Joule–Thomson effect, isentropic expansion and regenerative cooling.
What is the benefit of liquid oxygen?
Oxygenated water is a relatively new functional water product that has oxygen added to it during the canning or bottling process. The added oxygen is claimed to provide health benefits, including aiding exercise recovery, flushing toxins out of the body, and improving alcohol metabolism.
Is liquid oxygen expensive?
Liquid oxygen is lighter, easier to carry, and lasts longer than compressed oxygen, but it is also much more expensive. Medicare is seeking to reduce costs, and liquid oxygen is the most expensive oxygen delivery system.
