A fluidized bed discharge process for transferring solid particulate material from a high pressure vessel to lower pressure through successive zones of settling and transferring is disclosed, wherein said solid is maintained in a fluidized condition by the passage of a gas stream through said high pressure vessel from the base of said bed to the top of said vessel, involving conveying fluidized solid particulate material, by positive gas transfer, from a point in said vessel below the top of said bed, through the actuation of suitable valving means, to a settling zone or zones wherein said solid materials is separated from said gas which is vented back directly or indirectly into said vessel at a point above the point of conveying; upon the completion of conveying of said solid particulate material to said settling zone, actuating associated valving means to arrest all solid and gas flow to and from said settling zone; and actuating valve means associated with said settling zone to successively convey said solid particulate material from said settling zone to said convey zone or convey the gas from one said settling zone to a second settling zone.

A fluidized bed discharge process for transferring solid particulate material from a high pressure vessel to lower pressure through successive zones of settling and transferring, wherein said solid is maintained in a fluidized condition by the passage of a gas stream through a distributor plate in said high pressure vessel from the base of said bed to the top of said vessel, comprising: conveying fluidized solid particulate material, by positive gas transfer, from a point in said vessel below the top of said bed and above said distributor plate, through the actuation of suitable valving means, to a settling zone or zones wherein said solid material is separated from said gas which is vented back directly and indirectly into said vessel at a point above the point of conveying; upon the completion of conveying of said solid particulate material to said settling zone, actuating associated valving means to arrest all solid and gas flow to and from said settling zone; and actuating valve means associated with said settling zone to a transfer solid particulate material from said settling zone to a transfer zone or convey the gas from one said settling zone to a second settling zone.
