magnetic separation of oxygen from air

Jul 16, 2004 In an effort to develop a highly effective separation technology for oxygen operating in the liquefied natural gas (LNG) temperature range, the magnetic separation of oxygen from supercritical air was investigated using a laser holography interferometer. The experiment was carried out near the maxcondentherm (MC) point. For purposes of comparison, the same operation was carried out using ...

Jul 15, 2015 Physics says yes. And at the US Patent Office, it certainly looks like the answer is yes, according to (at least) this US patent application.Magnetic Separator Kleemann Mining Magnetic Separator.The abstract reads: A process for separating O$_2$ from air, that includes the steps effecting an increase in pressure of an air stream, magnetically concentrating O$_2$ in one portion of the pressurized air stream, the one portion then being an …

Feb 01, 2008 Therefore, there is a possibility of oxygen separation from atmospheric air under a strong magnetic field gradient. However, the magnetizing forces acting on these gases are very small, and the gas turbulence and the molecular diffusion caused by the concentration difference may easily lead to the remixing of oxygen and nitrogen.

These two factors are the affinity for certain liquids to dissolve more air and thus oxygen than some other liquids; and the fact that oxygen molecules are paramagnetic and can then be magnetically removed from these specific liquids or fluids as gaseous oxygen. Magnetic separation falls under two principal types of governing physical phenomena.

Air Separation Technology focuses on identification of new concepts and technologies for production of oxygen for use in gasification systems. Many gasification-based energy plants run more efficiently if the oxidant is oxygen rather air, but they rely on conventional cryogenic air separation which is expensive both in terms of capital expenditure and cost to operate.
