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 . An apparatus, comprising:
a casing defining an interior volume, the casing having a plurality of entrances configured to inject a gas into the interior volume, the casing further having a top and bottom opening; at least a first set of discs configured to rotate around an axis, the at least first set of discs placed within the interior volume and configured to rotate in a first direction; at least a second set of discs configured to rotate around the axis, the at least second set of discs placed within the interior volume and configure to rotate in a second direction, wherein the first direction is different than the second direction; a first shaft with a first end and a second end, the shaft connected to first set of discs; and a second shaft connected to the second set of discs, wherein upon rotation of the first shaft, the first set of discs is configured to rotate and wherein upon rotation of the second shaft the second set of discs is configured to rotate and wherein a fluid entering the casing through the top opening of the casing is separated into a liquid phase and a gas phase and wherein the liquid phase is configured to exit the bottom opening and the gas phase is configured to exit the top opening, wherein the plurality of entrances has a shape of one of a slot, a circle, an oval, a rectangle, a triangle, a pentagon or any other applicable shape.

2 . The apparatus according to claim 1 , wherein a surface of the at least first set of discs and second set of discs is configured with one of a grooved, waved and textured surface.

3 . The apparatus according to claim 1 , further comprising:
a driving arrangement connected to the first shaft and the second shaft, the arrangement configured to rotate the first shaft and the second shaft.

4 . The apparatus according to claim 3 , further comprising a gearbox connected to the driving arrangement.

5 . The apparatus according to claim 1 , wherein the second shaft is configured within the first shaft.

6 . The apparatus according to claim 1 , further comprising a set of nozzles configured to spray a fluid within the casing.

7 . The apparatus according to claim 6 , wherein each nozzle of the set of nozzles has a set of diametrically opposite injectors.

8 . The apparatus according to claim 1 , further comprising a set of split packing located within the casing.

9 . The apparatus according to claim 1 , wherein the first shaft and the second shaft are concentric in arrangement.

10 . The apparatus according to claim 9 , wherein the first shaft and second shaft are balanced.

11 . The apparatus according to claim 1 , wherein the fluid entering the casing through the top opening of the casing enters through the first shaft.

12 . The apparatus according to claim 11 , wherein the fluid is split into two fluid streams.

13 . 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; 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.

14 . The method according to claim 13 , further comprising one of adding and removing heat from the fluid after inserting the fluid stream.

15 . The method according to claim 13 , wherein the separating of the fluid stream into the liquid phase and the gas phase is along a tortuous path.

16 . The method according to claim 13 , further comprising changing a speed of at least the first set of discs and second set of discs.

17 . The method according to claim 13 , further comprising collecting at least one of the liquid phase and gas phase.

18 . The method according to claim 13 , wherein a user can control a speed and a direction of rotation of the first set of discs and the second set of disks.

19 . The method according to claim 13 , wherein the fluid stream is comprised of multiple types of liquids.

20 . The method according to claim 19 , wherein the multiple types of liquids have different physical properties.
