Abstract

The present disclosure relates to an absorber column apparatus for removing a selected component of a gas. The apparatus may have a first zone, a second zone and a third zone, wherein the first and third zones form a first domain through which a first fluid laden with a select gaseous component to be removed therefrom flows along concurrently with a second fluid. The second fluid at least substantially removes the select gaseous component from the first fluid to create a third fluid. The first fluid leaves the absorber column as a fourth fluid with the select gaseous component at least substantially removed therefrom. The second zone forms an active packing zone including a structure which forms an independent second domain in thermal communication with the first domain. The second receives a quantity of the third fluid and channels it through the second zone to help cool at least one of the first and second fluids.

Claims (32)

1. An absorber column apparatus for removing a selected component of a gas, the apparatus comprising:

a first zone, a second zone and a third zone;

the first and third zones forming a first domain through which a first fluid laden with a select gaseous component to be removed therefrom flows concurrently with a second fluid, and wherein the second fluid operates to at least substantially remove the select gaseous component from the first fluid to create a third fluid, and wherein the first fluid leaves the apparatus as a fourth fluid having had the select gaseous component at least substantially removed therefrom; and

the second zone forming an active packing zone including a structure which forms an independent second domain in thermal communication with the first domain, the second zone operating to receive a quantity of the third fluid and to channel the quantity of the third fluid through the second zone to help cool the at least one of the first fluid and the second fluid.

2. The apparatus of claim 1 , wherein the first, second and third zones are contiguous.

3. The apparatus of claim 1 , wherein the second zone is arranged between the first and third zones.

4. The apparatus of claim 1 , wherein the first, second and third zones form a straight linear arrangement.

5. The apparatus of claim 1 , wherein the second zone comprises an additively manufactured packing structure.

6. The apparatus of claim 5 , wherein the additively manufactured packing structure comprises a triply periodic minimal surface (TPMS) structure which operates to transfer heat from the first domain to the second domain.

7. The apparatus of claim 1 , wherein the second fluid comprises a solvent which is flowed in an opposite direction through the apparatus as the first fluid.

8. The apparatus of claim 1 , wherein the third fluid is input to the second zone at a first longitudinal end of the second zone, and withdrawn out from the apparatus at a second longitudinal end of the second zone.

9. The apparatus of claim 1 , further comprising a fourth zone forming an additional active packing zone for further assisting in cooling at least one of the first fluid and the second fluid.

10. The apparatus of claim 1 , wherein the second zone comprises between 1%-25% of an overall length of the apparatus.

11. The apparatus of claim 1 , wherein the second zone comprises approximately 10% of a total length of the apparatus.

12. An absorber column apparatus for removing a selected component of a gas, the apparatus comprising:

a first zone, a second zone and a third zone;

the first and third zones forming a first domain through which a first fluid laden with a select gaseous component to be removed therefrom flows along concurrently with a second fluid, and wherein the second fluid operates to at least substantially remove the select gaseous component from the first fluid to create a third fluid, and wherein the first fluid leaves the apparatus as a fourth fluid having had the select gaseous component at least substantially removed therefrom; and

the second zone being arranged between the first and third zones and linearly in line with the first and third zones; and

the second zone forming an active packing zone including a structure which forms an independent second domain in thermal communication with the first domain, the second zone operating to receive a quantity of the third fluid at a first longitudinal end, and to channel the quantity of the third fluid through the second zone to a second longitudinal end, to help cool both the first fluid and the second fluid.

13. The apparatus of claim 12 , wherein the active packing structure comprises an additively manufactured structure.

14. The apparatus of claim 12 , wherein the active packing structure comprise a triply periodic minimal surface (TPMS) structure.

15. The apparatus of claim 12 , wherein the second zone comprises between 5%-25% of an overall length of the apparatus.

16. The apparatus of claim 12 , wherein the second zone comprises approximately 10% of a total length of the apparatus.

17. The apparatus of claim 12 , wherein the second fluid comprises a solvent.

18. A method for removing a selected component of a gas using an absorber column, the method comprising:

flowing a first fluid laden with a select gaseous component through a first, second and third zones of the absorber column, in a first domain of the first, second and third zones;

flowing a second fluid through the first domain of the first, second and third zones concurrently with the first fluid;

using the second fluid to at least substantially remove the select gaseous component from the first fluid to thus create a third fluid, and wherein the first fluid leaves the absorber column as a fourth fluid having had the select gaseous component at least substantially removed therefrom; and

causing at least a portion of the third fluid to be channeled into the second zone, wherein the second zone is comprised of a structure and material which forms an independent second domain in thermal contact with the first domain, by which heat from at least one of the first fluid and the second fluid is transferred to the third fluid to create a fourth fluid; and

channeling the third fluid out of the second zone.

19. The method of claim 18 , wherein flowing the first and second fluids through the first, second and third zones comprises flowing the first and second fluids through a second zone formed by an active packing material.

20. The method of claim 19 , wherein flowing the first and second fluids through the active packing material comprises flowing the first and second fluids through an additively manufactured triply periodic minimal surface (TPMS) structure.
