Abstract

Systems and methods for gas processing are described that utilize two or more cells that are fluidly coupled to one another by a common liquid space. Via the common liquid space, each of the cells can be coupled to a fluid outlet. The cells can each include an absorber and/or other gas processing equipment. A feed gas can be separately fed to each of the cells for processing. The cells can be independently operable, such that not all of the cells must be operated simultaneously.

First claim

What is claimed is:

1. A method for gas processing, comprising:
feeding a flue gas stream to a first cell and a second cell, wherein the first cell and the second cell are disposed within a common housing, and wherein the first cell and the second cell share a common liquid space, wherein the common liquid space comprises a floor that slopes downward towards a fluid outlet coupled to each of the first cell and the second cell;
injecting a liquid into each of the first cell and the second cell via at least one liquid inlet; and
removing at least a portion of the liquid from the second cell via the common liquid space and a fluid outlet coupled to the first cell.

2. The method of claim 1 , further comprising shutting down operation of gas processing equipment in the second cell as a function of a volume of flue gas to be processed.

3. The method of claim 1 , wherein the first cell and the second cell share a common gas outlet.

4. The method of claim 1 , wherein each of the first cell and the second cell comprises a carbon capture system.

5. The method of claim 1 , wherein the common housing includes a liquid reservoir at a bottom portion of the common housing, and wherein the common liquid space comprises the liquid reservoir.

6. The method of claim 1 , wherein the at least one liquid inlet comprises a single common liquid distributor.

7. The method of claim 1 , wherein the at least one liquid inlet comprises a first liquid inlet and a second liquid inlet, wherein injecting the liquid into the first cell and the second cell comprises injecting a first portion of the liquid into the first cell through a first distributor, and wherein injecting the liquid into the first cell and the second cell comprises injecting a second portion of the liquid into the second cell through a second liquid distributor.

8. A method of gas processing, the method comprising:
feeding a gas stream to a plurality of cells, wherein the plurality of cells are all disposed within a common housing, wherein the plurality of cells share a common liquid space that is fluidly coupled to each of the plurality of cells and a liquid outlet,
injecting a liquid into one or more of the plurality of cells;
contacting the gas stream with the liquid in one or more of the plurality of cells to produce a processed gas stream;
removing the liquid through the liquid outlet; and
removing the processed gas stream through an exhaust outlet, wherein the common housing comprises a plurality of gas inlets coupled to each cell of the plurality of cells, wherein feeding the gas stream to the plurality of cells comprises feeding a portion of the gas stream through each gas inlet of the plurality of gas inlets to each cell of the plurality of cells.

9. The method of claim 8 , wherein the exhaust outlet is in fluid communication with each of the plurality of cells.

10. The method of claim 8 , wherein the exhaust outlet is only in fluid communication with a first cell of the plurality of cells.

11. The method of claim 8 , wherein one or more of the plurality of cells comprise a gas-liquid contacting surface, and wherein the contacting of the gas stream with the liquid occurs, at least in part, over the gas-liquid contacting surface.

12. The method of claim 8 , wherein at least a portion of the common liquid space comprises a floor that slopes downward towards the liquid outlet.

13. The method of claim 8 , wherein removing the liquid through the liquid outlet comprises pumping the liquid from the liquid outlet.

14. The method of claim 8 , wherein each cell of the plurality of cells comprises a fluid distributor, and wherein injecting the liquid into one or more of the plurality of cells comprises passing the liquid through the fluid distributor associated with the one or more of the plurality of cells.

15. The method of claim 8 , wherein injecting the liquid into one or more of the plurality of cells comprises passing the liquid through a common fluid distributor associated with the plurality of cells.

16. The method of claim 8 , wherein the common housing comprises one or more walls dividing adjacent cells of the plurality of cells.

17. The method of claim 16 , wherein the one or more walls comprise openings in a bottom portion of the one or more walls, wherein the method further comprises: passing the liquid from the one or more of the plurality of cells through the openings in the one or more walls to the liquid outlet.

18. The method of claim 8 , wherein the gas stream comprises a flue gas comprising carbon dioxide, and wherein the processed gas stream comprises the flue gas having a portion of the carbon dioxide removed therefrom.

19. A method of gas processing, the method comprising:
feeding a gas stream to a plurality of cells, wherein the plurality of cells are all disposed within a common housing, wherein the plurality of cells share a common liquid space that is fluidly coupled to each of the plurality of cells and a liquid outlet,
injecting a liquid into one or more of the plurality of cells;
contacting the gas stream with the liquid in one or more of the plurality of cells to produce a processed gas stream;
removing the liquid through the liquid outlet; and
removing the processed gas stream through an exhaust outlet, where at least one cell of the plurality of cells does not have any portion of the gas stream fed thereto.

20. The method of claim 8 , wherein the common housing includes a liquid reservoir at a bottom portion of the common housing, and wherein the common liquid space comprises the liquid reservoir.
