    摘要： A joint to connect a tubular ceramic element to a tubesheet. The joint has an internal seal housing to retain the tubular ceramic element and an external seal housing connected to the tubesheet to retain the internal seal housing. A ceramic-to-metal seal is located within the internal seal housing and a metal-to-metal seal is located between the internal seal housing and an external seal housing. The external seal housing is connected to the tubesheet. The internal seal housing is assembled in sections to allow assembly of the ceramic-to-metal seal to be assembled and tested prior to joining the tubular ceramic element to the tubesheet. After perfection of such seal, the internal seal housing and tubular ceramic element is inserted into the external seal housing and sealed within the external seal housing by the metal-to-metal seal.

    摘要： A vessel for use in a pressure swing adsorption gas separation process includes an enclosing wall which defines an enclosed space having a top region and a bottom region. An annular adsorbent bed is positioned within the enclosed space and has a porous outer wall, a porous inner wall and adsorbent material positioned between the walls. The porous outer wall is separated from the enclosing wall to create a gas feed channel therebetween, and the porous inner wall surrounds an inner tank whose wall surface is separated from the porous inner wall and creates a product flow channel therebetween. A gas feed/distribution baffle structure is positioned in the bottom region of the vessel and in fluid communication with the gas feed channel to provide a gas feed thereto. The gas feed enters the gas feed channel and the adsorbent bed via the porous outer wall and in a direction generally radially towards the inner porous wall and product flow channel. A product outlet is positioned in the bottom region and in fluid communication with the product flow channel, for collecting product gas passing thereinto via the porous inner wall from the adsorbent bed. A flexible membrane extends between the porous outer wall and the porous inner wall, at the upper extremities thereof, and is pressurized so as to bear upon the upper surface of the adsorbent material to prevent fluidization during gas flow.
