Abstract

Provided are apparatus and systems having a poppet valve assembly and swing adsorption separation techniques related thereto. A poppet valve includes a valve body, a plurality of static valves fixedly secured to the valve body and a single dynamic poppet valve having a plurality of openings. The plurality of static valves align and mate with the plurality of openings. The single dynamic poppet valve reciprocates to selectively open and close the plurality of static valves.

Claims

1. A poppet valve assembly comprising:

a valve body;

a plurality of static valves fixedly secured to the valve body;

a single dynamic poppet valve having a plurality of openings, wherein the plurality of static valves align and mate with the plurality of openings, the single dynamic poppet valve reciprocates to selectively open and close the plurality of static valves.

2. The poppet valve assembly according to claim 1, wherein the valve body has an inside wall, the inside wall having at least one flow vane protruding inwardly therefrom.

3. The poppet valve assembly according to claim 1, wherein the single dynamic poppet valve has a vane disposed between two of the openings.

4. The poppet valve assembly according to claim 3, wherein the valve body has an inside wall, the inside wall having at least one flow vane protruding inwardly therefrom.

5. The poppet valve assembly according to claim 1, wherein the single dynamic poppet valve has a first chamfer and at least one of the static valves has a second chamfer, the first chamfer and second chamfer configured to delay the flow through one of the respective openings formed by the movement of the dynamic poppet valve.

6. The poppet valve assembly according to claim 1, further comprising a shock absorber disposed within the valve body and configured to absorb the contact force for one or more of the dynamic poppet valve and the static valves.

7. The poppet valve assembly according to claim 1, wherein the openings have a circular cross-section.

8. The poppet valve assembly according to claim 1, wherein the openings have a non-circular cross-section.

9. A swing adsorption vessel comprising:

one or more adsorbent beds;

a plurality of poppet valve assemblies, each of the plurality of poppet valve assemblies being in fluid communication with the one or more adsorbent beds, each poppet valve assembly comprising;

a valve body;

a plurality of static valves fixedly secured to the valve body;

a single dynamic poppet valve having a plurality of openings, wherein the plurality of static valves align and mate with the plurality of openings, the single dynamic poppet valve reciprocates to selectively open and close the plurality of static valves.

10. The swing adsorption vessel according to claim 9, wherein the valve body has an inside wall, the inside wall having at least one flow vane protruding inwardly therefrom.

11. The swing adsorption vessel according to claim 9, wherein the single dynamic poppet valve has a vane disposed between two of the openings.

12. The swing adsorption vessel according to claim 11, wherein the valve body has an inside wall, the inside wall having at least one flow vane protruding inwardly therefrom.

13. The swing adsorption vessel according to claim 11, wherein the single dynamic poppet valve has a first chamfer and at least one of the static valves has a second chamfer, the first chamfer and second chamfer configured to delay the flow through one of the respective openings formed by the movement of the dynamic poppet valve.

14. The swing adsorption vessel according to claim 13, further comprising a shock absorber disposed within the valve body and configured to absorb the contact force for one or more of the dynamic poppet valve and the static valves.

15. The swing adsorption vessel according to claim 9, wherein the openings have a circular cross-section.

16. The swing adsorption vessel according to claim 9, wherein the openings have a non-circular cross-section.
