Abstract
A filter assembly is made for filtering hot gas within a cleanup system pressure vessel (22), where the filter assembly (60) contains a filter housing (62) having an interior chamber (66), and a filter element (28) attached to the bottom of a fail-safe/regenerator filter device (129) which contains a plurality of elongated passageway members either of a porous metal media tube type (120) or of a porous metal media honeycomb cartridge member type (130), where the passageway members are effective to facilitate enhanced capture of particulates in the event of filter element (28) failure.
