Patent ID: 7410524

Claim:
A process for removing organosilicon and halogenated contaminants from a gas stream to achieve a clean fuel gas, comprising the steps of: (a) passing the gas stream through a filter vessel including a filter media configured to remove organosilicon and halogenated contaminants from the gas stream, thereby producing a clean fuel gas and spent filter media; (b) removing a portion of the spent filter media from the filter vessel; (c) using a portion of the clean fuel gas to generate a hot inert gas; (d) using the hot inert gas to remove contaminants from the spent filter media, thereby regenerating the filter media; (e) returning the regenerated filter media to the filter vessel; and (f) using a portion of the clean fuel gas to treat the contaminants removed from the spent filter media, such that an exhaust from treating the contaminants is discharged without contacting the spent filter media.
