20120037000 | Apparatuses and Methods for Gas-Solid Separations Using Cyclones - Cyclones for gas-solid separators are described, which are especially applicable for use in a downflowing third stage separator (TSS) for the removal of dust particles, such as solid catalyst fines, from the flue gas streams exiting the catalyst regenerator in fluid catalytic cracking (FCC) processes. A number of important flow characteristics result from the configuration of the cyclones, particularly with respect to the relative axial lengths over which swirl vanes and central hubs of the cyclones extend. These characteristics include a decrease in growth of turbulent eddies that conventionally result from a sudden expansion, in open cross-sectional area, of gas exiting swirl vanes. | 02-16-2012 |
20140294682 | INCLINED BASEPLATE IN DEHYDROGENATION REACTOR - An inclined baseplate for a radial bed reactor improves solids flow from the bottom of the reactor. Gas flow can be improved by utilizing an aerated baseplate or by providing a non-porous section of outer perforated cylinder in the area below the level of the bottom of the inner perforated cylinder. | 10-02-2014 |

20100152020 | Process for Regenerating Catalyst - Disclosed is a catalyst distributor and process for spreading catalyst over a regenerator vessel. Nozzles disposed angular to a header of the distributor spread catalyst throughout a full cross section of the catalyst bed. | 06-17-2010 |
20110123412 | Centerpipe Design for Radial Flow Reactor - A device is presented for use as a centerpipe in a radial flow reactor, or for a radial flow adsorption bed. The device includes a plurality of stacked slotted cylindrical sections and frustums. The design retains the particles in a solid particulate bed that can be flowing through the reactor. The frustums provide covers to the cylindrical sections to prevent the flow of solid particles back through the slots in the cylindrical sections. | 05-26-2011 |
20130334101 | PROCESS AND APPARATUS FOR DISTRIBUTING HYDROCARBON FEED AND CATALYST - A process and apparatus for fluid catalytic cracking feeds catalyst to a chamber of a riser. The catalyst exits the chamber and passes through a plenum and into a reaction zone through a plurality of tubes which distribute the catalyst uniformly over a cross section of the reaction zone of the riser. A hydrocarbon feed is fed to the plenum. The hydrocarbon feed passes from the plenum into the reaction zone through a plate comprising a multiplicity of openings which distribute the hydrocarbon feed uniformly over a cross section of the reaction zone of the riser. The feed is contacted with the catalyst in a reaction zone of the riser. | 12-19-2013 |
