Abstract

A sorption arrangement for a gas turbine includes a sorbent-laden media. The sorbent-laden media is positioned within an inlet system for the gas turbine. The sorbent-laden media includes one or more sorbents. The sorbent-laden media contacts inlet air passing through the inlet system for the gas turbine such that gas phase contaminants are removed from the inlet air by the sorbent-laden media. A method of removing gas phase contaminants within an inlet system of a gas turbine is provided.

Claims

1. A sorption arrangement for a gas turbine, the sorption arrangement including:

an inlet system for the gas turbine, the inlet system including a substantially hollow chamber;

a support structure positioned within the substantially hollow chamber, the support structure including an exterior surface configured to contact inlet air passing through the substantially hollow chamber of the inlet system; and

a sorbent-laden media positioned on the support structure, the sorbent-laden media including one or more sorbents, wherein the support structure defines a substantially hollow interior with one or more openings extending through the support structure between the hollow interior of the support structure and the sorbent-laden media,

wherein the sorbent-laden media is configured to contact inlet air passing through the substantially hollow chamber of the inlet system for the gas turbine such that gas phase contaminants are removed from the inlet air by the sorbent-laden media.

2. The sorption arrangement of claim 1, further including a second support structure positioned within the substantially hollow chamber, the second support structure including a second exterior surface to contact the inlet air passing through the substantially hollow chamber of the inlet system and the sorbent-laden media positioned on the second support structure.

3. The sorption arrangement of claim 1, further including a blower attached with respect to the hollow interior of the support structure, the blower configured to move air and create a negative pressure within the hollow interior.

4. The sorption arrangement of claim 3, wherein the blower is configured to deliver sorbent-laden air flow through the hollow interior of the support structure to the sorbent-laden media.

5. The sorption arrangement of claim 1, further including a heating device attached with respect to the support structure.

6. The sorption arrangement of claim 5, wherein the heating device is configured to heat the support structure by Joule heating.

7. The sorption arrangement of claim 5, wherein the heating device includes high temperature air from the gas turbine.

8. A sorption arrangement for a gas turbine, the sorption arrangement including:

an inlet system for the gas turbine, the inlet system includes a substantially hollow chamber;

a support structure positioned within the substantially hollow chamber, the support structure including an exterior surface, wherein the support structure defines a substantially hollow interior with one or more openings extending through the support structure between the hollow interior of the support structure and the sorbent-laden media;

a heating device attached with respect to the support structure and configured to heat the support structure; and

a sorbent-laden media supported by the support structure, the sorbent-laden media including one or more sorbents, wherein the sorbent-laden media is configured to contact inlet air passing through the inlet system for the gas turbine such that gas phase contaminants are removed from the inlet air by the sorbent-laden media.

9. The sorption arrangement of claim 8, further including a blower attached with respect to the hollow interior of the support structure, the blower configured to move air and create a negative pressure within the hollow interior.

10. The sorption arrangement of claim 9, wherein the blower is configured to remove sorbent-laden air flow through the hollow interior of the support structure to the sorbent-laden media.

11. The sorption arrangement of claim 8, wherein the heating device is configured to heat the support structure by Joule heating.

12. The sorption arrangement of claim 8, wherein the heating device is configured to heat the support structure using high temperature air from the gas turbine.

13. A method of removing gas phase contaminants within an inlet system of a gas turbine, the method including the steps of:

providing an inlet system for the gas turbine, the inlet system comprising;

a substantially hollow chamber;

a support structure positioned within the substantially hollow chamber, the support structure including an exterior surface configured to contact inlet air passing through the substantially hollow chamber of the inlet system; and

a sorbent-laden media positioned on the support structure, the sorbent-laden media including one or more sorbents, wherein the support structure defines a substantially hollow interior with one or more openings extending through the support structure between the hollow interior of the support structure and the sorbent-laden media,

wherein the sorbent-laden media is configured to contact inlet air passing through the substantially hollow chamber of the inlet system for the gas turbine such that gas phase contaminants are removed from the inlet air by the sorbent-laden media;

passing inlet air by the sorbent-laden media;

removing gas phase contaminants from the inlet air with the sorbent-laden media; and

heating the sorbent-laden media to extract the gas phase contaminants from the sorbent-laden media.

14. The method of claim 13, further including the step of:

creating a negative pressure within the hollow interior of the support structure to extract the gas phase contaminants from the sorbent-laden media and through the support structure to the hollow interior.

15. The method of claim 14, wherein the heating the sorbent-laden media includes Joule heating the support structure.

16. The method of claim 13, further including the step of delivering sorbent-laden air flow to the sorbent-laden media.
