Abstract
A process for something separating oxygen from air includes mixing the air with hydro fluoro ether in a closed vessel for a desired period of time so that the oxygen from the air is adsorbed into the hydro fluoro ether, discharging the oxygen-adsorbed hydro fluoro ether from the closed vessel, and flashing the oxygen-adsorbed hydro fluoro ether into a chamber so that so as to separate the oxygen from the hydro fluoro ether. Nitrogen is separated from the air as the oxygen is adsorbed in the hydro fluoro ether in the closed vessel. The step of flashing that includes passing the elevated pressure oxygen-adsorbed hydro fluoro ether across a restricting orifice so as to evaporate the oxygen from the hydro fluoro ether.
