    摘要: A distributor assembly for a multi-bed, downflow catalytic reactor is disclosed. The distributor assembly is configured for disposal and fixable attachment between the inner surfaces of the walls of a multi-bed downflow cylindrical reactor wall and for disposal between vertically stacked catalyst beds within the reactor. The assembly includes: (a) a collection plate configured for substantially horizontal disposal between the walls of a cylindrical reactor; (b) a plurality of generally arc-shaped elongated baffles disposed in a staggered, substantially symmetrical pattern about the collection plate; (c) a first mixing zone configured to be bounded on the bottom by the collection plate, on one side by a wall of a cylindrical reactor, and on the opposite side by the outer surface of the elongated baffles; (d) a cylindrical weir fixably attached to the collection plate about the outlet; (e) a second mixing zone bounded on the bottom by the collection plate, on one side by the outer surface of the cap and the first cylindrical weir, and on the opposite side by the inner surface of the elongated baffles; (f) a cap disposed over and about the first cylindrical weir, thereby forming a third mixing zone, plurality of semi-spiral-shaped baffles disposed in the third mixing zone, the semi-spiral-shape; (g) baffles having an elongated shape, having one lateral edge fixed to an inner surface of the cap or an opposite lateral edge fixed to an outer surface of the first cylindrical weir; (h) a substantially doughnut-shaped screen member disposed over a top portion of the cylindrical weir; (i) a plurality of fourth-mixing-zone baffles fixably attached to a top surface of the doughnut-shaped screen member; and (j) a plurality of quench gas ports disposed in the second mixing zone.

    摘要: An apparatus and method for contacting fluids in a fluid-solids contacting chamber is disclosed. The fluid-solid contacting chamber has a plurality of beds, and the chamber comprises a plurality of conduits and outlet ports that are capable of providing improved fluid distribution of fluids that are introduced above or between the beds. One or more conduits are arranged within a single conduit, which provides a compact and inexpensive assembly for conveying the fluids to each conduit's outlet port. In operation, the fluid flow to the outlet port of each conduit is regulated within that outlet port's most efficient operating range, and since the flows can regulated simply by hand, the method of this invention can be practiced readily. Catalytic condensation and other hydrocarbon process units that employ this invention will have increased on-stream efficiencies and realize significant economic benefits.

    摘要: The invention is directed to a bypass device for extending the operating life of fixed bed reactors. The device may be placed within a fixed catalyst bed to partition the bed into a first top bed and a second virtual bed. The bypass device allows any fluid feedstock to bypass the first top bed of the fixed catalyst bed as it fouls and enter the second virtual bed under conditions that promote depositing any foulants contained in the bypass flow on the top surface of the second virtual bed rather than in the interstices of the second virtual bed. The invention also relates to an improved fixed bed reactor comprising the inventive bypass device and a method for extending the operating life of a fixed bed reactor that employs the inventive bypass device.
