摘要： A fluid solid-contacting device eliminates the accumulation of deposits behind distribution collection conduits, reduces the differential expansion between the conduits and a containment vessel, and improves fluid distribution by extending the perforations into a back side of a distribution conduit that abuts the vessel. This apparatus has greatest application to scallop-shaped conduits that are commonly used in radial flow reactors. The perforations, extended into the back side of the scallop, ventilate the area between the scallop and the vessel holding the scallops.

摘要： Void blowing by gas flow through a bed of particulate material is avoided by the use of a cover plate that eliminates void spaces at the top of the bed and a vertical duct that allows a head of particulate material to be maintained above the cover plate. The particle bed is arranged in the usual fashion using inner and outer screens to hold particulate material in a vertically extended bed into which particulate material is intermittently added and withdrawn. The top of the particulate bed is contacted by an imperforate cover plate that is sloped up to an inlet opening that has a smaller cross-sectional area than the area of the bed. The cover plate has a slope which is greater than the angle of the repose of the particles so that particles filling the top section of the bed will be free of void spaces. The cover plate also has a relatively small inlet opening so that a small volume of catalyst particles can provide a head of particles above the inlet opening to resist upward pressure that otherwise forms voids at the inlet screen surface. This cover plate arrangement also minimizes bed heights and overall reactor height necessary to provide the head of particles for resisting upward pressure.

摘要： Method for effecting contact of a gas with light particles of solid matter, where the particles are retained within particle retention screens to form a bed of particles and the particles move downward in plug flow by means of gravity. When the particles are light, that is, of relatively small size and low density, the velocity of the gas may be sufficiently high that downward movement of particles is hindered by the horizontal forces exerted on the particles by the flowing gas. This invention provides that gas flows through the bed of particles in a downwardly sloping direction instead of in a horizontal direction, so that the force exerted on a particle has a horizontal component and a downward vertical component. The vertical component of the force resulting from gas flow, along with the gravity force on a particle, is sufficient to overcome the frictional resistance to downward movement of a particle which results from the horizontal component of the flowing gas force.

摘要： An apparatus is shown for contacting a bed of particulate material with a cross flowing fluid, which maintains the bed of particulate material within a retention volume. The apparatus includes partitions for retaining particles, with apertures disposed within the partitions. The apertures are covered by louvers that extend above the edges of the apertures to prevent solid particles from spilling through inlet apertures. And the apparatus includes baffles to inhibit erosion of the particles by redirecting the inlet gas flow.

摘要： An dilute phase transport riser for the contacting of particles with a gas uses redistributors along the length of the riser to prevent the formation of localized regions of high particle concentration along the wall of the riser. A series of redistributors extend transversely across the riser to redistribute the particles and the gas. The redistributor can comprise radially extended spokes or simple rectangular grates spaced at regular intervals along the length of the riser. The arrangement is particularly suited for FCC application where the catalyst tends to form pickets or streamers of catalyst that may slip backward along the length of a vertical riser.

摘要： A reactor arrangement and process for indirectly contacting a reactant stream with a heat exchange stream uses multiple passes of the heat exchange stream in a transverse flow arrangement to control temperature conditions over the width and length of channels through which the reactant passes. The heat transfer coefficient may be varied by changing the number and/or the arrangement of the corrugations along the plates or adding a heat adjustment plate to a channel containing the heat exchange fluid. The reactor arrangement and process of this invention may be used to operate a reactor under isothermal or other controlled temperature conditions. The variation in corrugation arrangements within a single heat exchange section is highly useful in maintaining a desired temperature profile in an arrangement having a cross-flow of heat exchange medium relative to reactants. The corrugations arrangement eliminates or minimizes the typical step-wise approach to isothermal conditions. Multiple heat exchange fluid inputs are particularly useful in fixed bed process arrangements where the temperature of the heat exchange fluids may be adjusted to suit changes in the activity profile through the bed that results from catalyst deactivation.
