摘要： One exemplary embodiment can include an apparatus for transferring catalyst from a regeneration zone to a reaction zone in a hydrocarbon conversion unit. The hydrocarbon conversion unit can include a transfer vessel, and first, second, and third lines. The transfer vessel can transfer regenerated catalyst from the regeneration zone at a first pressure to the reaction zone at a second pressure where the second pressure is greater than the first pressure. Generally, the first line communicates the catalyst to the transfer vessel and is coupled to a first valve to allow catalyst into the transfer vessel and the second line communicates the catalyst from the transfer vessel and is coupled to a second valve to allow catalyst out of the transfer vessel. The third line for allowing the passage of gas therethrough may be at a pressure higher than the first pressure having a first portion communicating with the transfer vessel and having a second portion coupled to third and fourth valves. Each of the third and fourth valves can have a first position that is open and a second position that is closed, which may correspond, respectively, to the opening and closing of the first and second valves to allow gas to pass therethrough.

摘要： An apparatus for use in radial flow reactors is presented. The apparatus includes a first partition and a second partition with support members coupled therebetween. The first partition includes a first opening and a second opening to allow the passage of fluid therethrough. A baffle extends into a flow channel formed by adjacent support members to obstruct an upper or lower portion of the first opening to interrupt a portion of the fluid flow therethrough.

摘要： An apparatus is presented for the mixing of a feed fluid with a process fluid between two adsorbent beds. The apparatus creates a space for mixing and redistributing a fluid mixture between the two adsorbent beds, where a process fluid is received from the upper adsorbent bed, and a distributor box passes the feed fluid to space between the adsorbent beds and mixes the feed fluid with the process fluid. The mixture is then redistributed and passed through to the lower adsorbent bed.

摘要： Method and apparatus are provided for transferring particles from an upper zone through an intermediate zone to a lower zone. The transfer of particles between the zones through valveless conduits is regulated by varying the pressure of the intermediate zone and the flow rate of gas passing through the valveless conduits. A body within the lower zone is in particle communication with a valveless conduit and obstructs the particle flow within the lower zone.
