Abstract

Embodiments presented provide for a multirotational counter rotating reactor. The reactor is configured to accept a fluid stream and separate the fluid stream into high quality liquid and gaseous phases through spinning of the sets of discs as well as through performing a heat transfer to the fluid stream.

First claim

What is claimed is:

1. A method for separating a fluid stream into a liquid phase and a gas phase, comprising:
providing the fluid stream to a rotating packed bed arrangement;
inserting the fluid stream into the packed bed arrangement;
rotating a first set of discs within a casing of the packed bed arrangement in a first direction;
rotating a second set of discs with the casing of the packed bed arrangement in a second direction, wherein the first direction and the second direction are counterrotating, wherein the fluid stream contacts both the first set of discs and the second set of discs, wherein the first and second sets of discs are coupled to respective first and second shafts arranged in a nested shaft assembly, wherein the nested shaft assembly comprises a plurality of fluid ports at a respective plurality of axial positions, wherein each fluid port of the plurality of fluid ports is configured to route a flow into one or more flow paths of a plurality of flow paths between the first and second sets of discs;
separating the fluid stream into the liquid phase and the gas phase through contact of the fluid stream with the first set of discs and second set of discs; and
discharging the liquid phase and the gas phase from the rotating packed bed arrangement.

2. The method according to claim 1 , further comprising adding or removing heat from the fluid stream after inserting the fluid stream.

3. The method according to claim 1 , wherein the separating of the fluid stream into the liquid phase and the gas phase is along a tortuous path.

4. The method according to claim 1 , further comprising changing a speed of at least the first set of discs and the second set of discs.

5. The method according to claim 1 , further comprising collecting at least one of the liquid phase or gas phase.

6. The method according to claim 1 , comprising independently controlling a speed and a direction of rotation of the first set of discs and the second set of discs.

7. The method according to claim 1 , wherein the fluid stream is comprised of multiple types of liquids.

8. The method according to claim 7 , wherein the multiple types of liquids have different physical properties.

9. The method according to claim 1 , wherein the plurality of fluid ports comprise a plurality of radial fluid ports.

10. The method according to claim 1 , wherein the nested shaft assembly defines the plurality of fluid ports at first and second axial ends of the respective first and second shafts.

11. The method according to claim 1 , wherein the first sets of discs, the second set of discs, or both, comprises:
a first disc portion extending crosswise to a rotational axis of the nested shaft assembly; and a second disc portion coupled to and extending crosswise to the first disc portion.

12. The method according to claim 11 , wherein each of the first and second sets of discs comprises the first and second disc portions, the second disc portions are coupled to the first set of discs at a first plurality of radial positions, the second disc portions are coupled to the second set of discs at a second plurality of radial positions different from the first plurality of radial positions, and the second disc portions of the first and second sets of discs at least partially overlap in the axial direction relative to the rotational axis.

13. The method according to claim 1 , comprising:
supplying flows into the rotating packed bed arrangement in both a radial inward direction and an axial inward direction relative to a rotational axis of the nested shaft assembly;
discharging the liquid phase in a first axial outward direction away from the rotating packed bed arrangement; and
discharging the gas phase in a second axial outward direction away from the rotating packed bed arrangement, wherein the first and second axial outward directions are opposite of one another.
