1. A filtration system for use in a gas turbine engine assembly, said system comprising:
- an array of perforated tubes in flow communication with a flow of intake air, wherein each perforated tube comprises a solids inlet and a solids outlet, and wherein the array of perforated tubes are arranged such that at least some intake air of the gas turbine engine assembly only circulates around an exterior of each one of the array of perforated tubes without passing through said perforated tubes, such that at least some of the intake air passes to the gas turbine engine assembly without passing through said perforated tubes when traveling through the filtration system; and
a solids feed system comprising a feed line coupled in flow communication with said solids inlet and configured to channel sorbent material through each perforated tube in said array, wherein the sorbent material is configured to remove gaseous contaminants entrained in the flow of intake air.

Abstract
A filtration system and methods of assembly and operation are provided. The filtration system includes an array of perforated tubes in flow communication with a flow of intake air. Each perforated tube comprises a solids inlet and a solids outlet. The system also includes a solids feed system comprising a feed line coupled in flow communication with said solids inlet and configured to channel sorbent material through each perforated tube in said array. The filtration system also includes a monitoring arrangement for monitoring a parameter associated with the intake air, and varying the operation of the system based upon said parameter.

13. A gas turbine engine assembly comprising:
-
a filter house having a filtration system, the filtration system comprising; an array of perforated tubes in flow communication with a flow of intake air, wherein each perforated tube comprises a solids inlet and a solids outlet, and wherein the array of perforated tubes are arranged such that at least some intake air of the gas turbine engine assembly only circulates around an exterior of each one of the array of perforated tubes without passing through said perforated tubes, such that at least some of the intake air passes to the gas turbine engine assembly without passing through said perforated tubes when traveling through the filtration system; a solids feed system comprising a feed line coupled in flow communication with said solids inlet and configured to channel sorbent material through each perforated tube in said array, wherein the sorbent material is configured to remove gaseous contaminants entrained in the flow of intake air in a duct coupled to an outlet of said filter house, wherein said duct is configured to channel the flow of intake air downstream therefrom; and a monitoring arrangement for monitoring a parameter of the intake air upstream and downstream from the array of perforated tubes, the monitoring arrangement operable to vary at least one of a recirculation, regeneration, and replacement frequency of said sorbent material based upon said monitored parameter. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. A method of assembling a filtration system for use in a gas turbine assembly, said method comprising:
-
providing an array of perforated tubes that each include a solids inlet and a solids outlet, wherein the array of perforated tubes is configured to be in flow communication with a flow of intake air and wherein the array of perforated tubes are arranged such that at least some intake air of the gas turbine engine assembly only circulates around an exterior of each one of the array of perforated tubes without passing through said perforated tubes, such that at least some of the intake air passes to the gas turbine engine assembly without passing through said perforated tubes when traveling through the filtration system; and coupling a feed line of a solids feed system in flow communication with the solids inlet, wherein the solids feed system is configured to channel sorbent material through each perforated tube in the array, the sorbent material configured to remove gaseous contaminants entrained in the flow of intake air. - View Dependent Claims (22, 23, 24, 25)
