Patent ID: 8110028

Claim:
A system for removing organosilicon and halogenated contaminants from a gas stream to achieve a clean fuel gas, comprising: (a) 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) a regeneration vessel configured to remove contaminants from spent filter media; (c) a filter media transfer subsystem configured to transfer spent filter media from the filter vessel to the regeneration vessel, and to transfer regenerated filter media from the regeneration vessel to the filter vessel; (d) a hot inert gas generator configured to use a portion of the clean fuel gas to generate a hot inert gas, the hot inert gas generator being coupled in fluid communication with the filter vessel to receive the clean fuel gas, and with the regeneration vessel, to direct hot inert gas into the regeneration vessel to regenerate the spent filter media; (e) a flare subsystem configured to use a portion of the clean fuel gas to treat contaminants removed from the spent filter media by the hot inert gas, the flare subsystem being coupled in fluid communication with the filter vessel to receive the clean fuel gas, and with the regeneration vessel to receive the hot inert gas loaded with contaminants removed from the regenerated filter media, the flare subsystem being configured to discharge exhaust from treating the contaminants without allowing the exhaust to contact the spent filter media; and, (f) a controller configured to automate operation of the filter media transfer subsystem.
