Title (EN) APPARATUS AND METHOD FOR SEPARATING LIQUID OXYGEN FROM LIQUIFIED AIR
(FR) APPAREIL ET PROCÉDÉ POUR SÉPARER L'OXYGÈNE LIQUIDE DE L'AIR LIQUÉFIÉ
Abstract:
(EN) An apparatus and method of separation of LOX and other commercially valuable components, such as LAr from liquefied air, which consists primarily of LN2. Strong magnetic field gradient and gravity are used to separate LOX from liquefied air, based upon the different magnetic properties of LOX and LN2. The apparatus and method employ a magnetic field gradient to levitate the LN2 and LAr diamagnetic components of liquid air while accelerating the paramagnetic LOX component toward the bottom to achieve oxygen separation. In other embodiments, a leak valve system can be used.
(FR) L'invention porte sur un appareil et sur un procédé de séparation de LOX et d'autres composants de valeur commerciale, tels que le LAr à partir d'air liquéfié, qui est principalement constitué de LN2. Un fort gradient de champ magnétique et la gravité sont utilisés pour séparer le LOX de l'air liquéfié, sur la base des différentes propriétés magnétiques du LOX et du LN2. L'appareil et le procédé utilisent un gradient de champ magnétique pour faire léviter les composants LN2 et LAr diamagnétiques de l'air liquide tout en accélérant le composant de LOX paramagnétique vers le fond pour obtenir une séparation d'oxygène. Dans d'autres modes de réalisation, un système de vanne de fuite peut être utilisé.
