Abstract

A magnetic/energetic apparatus for purifying gas mixtures comprises a vortex tube and magnetic elements. Such an apparatus can include an inlet valve configured to receive a gas mixture having one or more disposed paramagnetic gas species and one or more diamagnetic gas species; a high-shear environment energetic separation chamber coupled to the inlet valve; a plurality of magnetic elements coupled to an outer wall of the high-shear environment separation chamber, wherein each of the plurality of magnetic elements are arranged so as to have a respective pole alternating in polarity with respect to an adjacently positioned magnetic element so as to induce a field gradient between each of the adjacently positioned magnetic elements and within the inner wall of the high-shear environment separation chamber; and at least one exit valve so as provide a substantially separated one or more paramagnetic gas species from the one or more diamagnetic gas species.

First claim

We claim:

1. A magnetic/energetic apparatus for purifying gas mixtures, comprising:
an inlet valve configured to receive a gas mixture having one or more disposed paramagnetic gas species and one or more diamagnetic gas species;
a separation chamber coupled to the inlet valve, wherein the separation chamber has a circumference and a length which extends between a distal end and a proximal end;
a plurality of magnetic elements coupled to an outer wall of the separation chamber wherein the plurality of magnetic elements are placed lengthwise in a circumferentially arranged pattern about the circumference of the separation chamber with each magnetic element of the plurality of magnetic elements having a respective pole alternating in polarity with respect to each adjacently positioned magnetic element of the plurality of magnetic elements so as to induce a field gradient between each of the adjacently positioned magnetic elements and within an inner wall of the separation chamber; and
at least one exit valve configured at the proximate end and at least one exit valve at the distal end so as provide a substantially separated one or more paramagnetic gas species from the one or more diamagnetic gas species.

2. The apparatus of claim 1 , wherein the magnetic/energetic apparatus comprises at least one of: a counter-flow straight vortex tube or a counter-flow conical vortex tube.

3. The apparatus of claim 1 , wherein the plurality of magnetic elements are rare earth element bar magnets selected from material selected from the group consisting of Neodymium (Nd) and Samarium Cobalt (SmCo).

4. The apparatus of claim 1 , wherein the plurality of magnetic elements are configured from superconductor magnet materials selected from the group consisting of Niobium-titanium (Nb—Ti), Niobium-Tin (Nb3Sn), and Yttrium barium copper oxide (YBCO).

5. The apparatus of claim 4 , wherein the superconductor magnet materials are configured as electromagnets.

6. The apparatus of claim 1 , wherein the one or more disposed paramagnetic gas species provided at the distal end substantially comprises oxygen.

7. The apparatus of claim 6 , wherein the oxygen provided at the distal end is liquified.

8. The apparatus of claim 1 , wherein a one or more separated disposed diamagnetic gas species comprises nitrogen and argon.

9. The apparatus of claim 1 , wherein the one or more disposed paramagnetic gas species provided at the proximate end substantially comprises oxygen.

10. The apparatus of claim 1 , wherein the magnetic/energetic apparatus is configured with an inlet temperature of 89 Kelvin (K) to 90 Kelvin (K) and an inlet pressure of 305 kPa to 320 kPa.

11. The magnetic/energetic apparatus of claim 1 wherein at least one of the plurality of magnetic elements is comprised of magnetic elements configured as a plurality of solenoids arranged in series along the length of the separation chamber.

12. The magnetic/energetic apparatus of claim 11 further comprising a control for pulsing each of the plurality of solenoids.

13. A method for separation of a component from a gaseous mixture of paramagnetic species and diamagnetic species, comprising:
receiving a gas mixture having one or more disposed paramagnetic gas species and one or more disposed diamagnetic gas species into a separation chamber, wherein the separation chamber has a circumference and a length which extends between a distal end and a proximal end;
separating the received one or more disposed paramagnetic gas species and one or more diamagnetic gas species via a counter-flowing pair of vortices configured in the separation chamber;
inducing a magnetic field gradient in the separation chamber using a plurality of magnetic elements coupled to an outer wall of the separation chamber wherein the plurality of magnetic elements are placed lengthwise in a circumferentially arranged pattern about the circumference of the separation chamber with each magnetic element of the plurality of magnetic elements having a respective pole alternating in polarity with respect to each adjacently positioned magnetic element of the plurality of magnetic elements so as to induce the magnetic field gradient between each of the adjacently positioned magnetic elements, wherein the one or more disposed paramagnetic gas species are magnetically contained adjacent the inner wall of the separation chamber resulting from the induced magnetic field gradient so as to aid in the separating of the received one or more disposed paramagnetic gas species; and
promoting the one or more disposed paramagnetic gas species to exit liquified at the distal end and to promote a residual of the one or more disposed paramagnetic gas species to exit at the proximate end so as to substantially separate from the one or more disposed diamagnetic gas species.

14. The method for separation of claim 13 , further comprising configuring the separation chamber with an inlet temperature of 89 Kelvin (K) to 90 Kelvin (K) and an inlet pressure of 305 kPa to 320 kPa.

15. The method for separation of claim 13 , further comprising configuring the induced magnetic field gradient with a magnetic force exceeding that of a centrifugal force resulting from the counter-flowing pair of vortices in the separation chamber.

16. The method for separation of claim 13 , further comprising configuring the induced magnetic field gradient with a magnetic flux density in a range of 0.5 Tesla up to 30 Tesla.

17. The method for separation of claim 13 , further comprising electromagnetically pulsing the adjacently placed plurality of magnetic elements configured as electromagnets so as to promote movement of the one or more disposed paramagnetic gas species to the distal end.

18. The method for separation of claim 13 , further comprising separating oxygen from at least one of argon and nitrogen for byproduct recovery.
