Systems for extracting oxygen from a fluid

A method of extracting oxygen from a fluid using a separator, the separator including:

• a tube having a wall surrounding an interior portion of the tube, at least one aperture formed in the wall, and at least one pair of C-shaped magnets positioned adjacently to the at least one aperture, each C-shaped magnet of the at least one pair having a north pole and a south pole, wherein at least a portion of the wall includes four pairs of convex portions and four pairs of concave portions forming a cross-sectional “X” shape, wherein the at least a portion of the wall having the cross-sectional “X” shape is positioned between the at least one pair of C-shaped magnets such that:
• the north pole of a first C-shaped magnet of the at least one pair is positioned adjacently to a first concave portion of the four pairs of concave portions and directly across the interior portion of the tube opposite the north pole of a second C-shaped magnet of the at least one pair positioned adjacently to another concave portion of the four pairs of concave portions;
• and
• the south pole of the first C-shaped magnet is positioned adjacently to a second concave portion of the four pairs of concave portions and directly across the interior portion of the tube opposite the south pole of the second C-shaped magnet positioned adjacently to yet another concave portion of the four pairs of concave portions,
• and wherein the method comprises the steps of:
• forming a magnetic field gradient between:
• the north pole and the and south pole of the first C-shaped magnet;
• the north pole and the south pole of the second C-shaped magnet;
• the north pole of the first C-shaped magnet and the south pole of the second C-shaped magnet;
• and
• the south pole of the first C-shaped magnet and the north pole of the second C-shaped magnet,
• to thereby cause the magnetic field gradient to extend into and within at least the four pairs of convex portions defining four portions of the interior portion of the tube having the cross-sectional “X” shape;
• first flowing a fluid including oxygen lengthwise through the separator;
• and
• second flowing at least a portion of the oxygen removed from the fluid performance of the first flowing step out of the separator via the at least one aperture.

A method of extracting oxygen from a fluid using a separator including:

• a tube having a wall surrounding an interior portion of the tube, at least one aperture formed in the wall, and at least one permanent magnet positioned adjacently to the at least one aperture and having a north pole and a south pole, wherein:
• at least a portion of the wall includes a plurality of convex portions and a plurality of concave portions forming a cross-sectional “X” shape;
• the at least one permanent magnet comprises a pair of C-shaped magnets;
• and
• the at least a portion of the wall having the cross-sectional “X” shape is positioned between the pair of C-shaped magnets such that:
• the north pole of a first C-shaped magnet of the pair is positioned directly across the interior portion of the tube opposite the north pole of a second C-shaped magnet of the pair;
• and
• the south pole of the first C-shaped magnet of the pair is positioned directly across the interior portion of the tube opposite the south pole of the second C-shaped magnet of the pair,
• the method comprising the steps of:
• forming a magnetic field gradient between the north and south poles of the at least one permanent magnet and extending into the interior portion of the tube;
• first flowing a fluid including oxygen lengthwise through the separator;
• and
• second flowing at least a portion of the oxygen removed from the fluid during performance of the first flowing step out of the separator via the at least one aperture.
