Filtration system for use in a gas turbine engine assembly and method of assembling thereof

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.
