摘要： A baffle-style stripper for an FCC process comprising sloped baffles in which a greater volumetric flow rate of stripping medium permeates openings in a bottom section of the baffle than through a top section of the baffle for low catalyst flux stripping operations. When low catalyst flux is used, the catalyst runs from baffle to baffle closer to the bottom edge of the baffle. Hence, more fluidization from stripping medium is concentrated near the lower edge of the baffle. The greater fluidization at the bottom section of the baffle is accomplished by providing greater opening area per baffle area in the lower section of the baffle than in the top section of the baffle.

摘要： An FCC apparatus uses a cantilevered support for supporting baffles in a stripping vessel. Only one end of the support is fastened to a wall of a contacting conduit or a wall of the stripping vessel and the other end is spaced apart from the near wall of the contacting conduit or the stripping vessel. The arrangement provides for easier maintenance and accommodates differential thermal expansion.

摘要： A baffle-style stripper for an FCC process having a complete or nearly complete coverage of stripping openings over the sloped surface of the baffle will provide improved stripping efficiency and catalyst flux through the stripper. The complete distribution of relatively small openings over the entire surface of a sloped baffle has been found to interrupt relatively dense streamers of catalyst that were previously not known to exist and which short-circuited the contact of the stripping fluid with the catalyst. Spreading out the stripping gas across the sloped area of the baffle to a much greater extent than has been practiced in the past has now been found to promote active contacting of the catalyst with the stripping fluid over the entire volume of the stripper between the baffles.

摘要： An FCC feed distributor mixes fresh catalyst entering the riser with steam to create a dense bubbling bed of catalyst. Fluidized catalyst rises from the dense bed around a conical section supported from the bottom of the riser. The conical section accelerates the catalyst by reducing the flow area into a small width annulus. As fast fluidized catalyst flows to the annulus, a diverter outwardly redirects an axially flowing feed stream to discharge feed radially into the catalyst as it flows by the annular section. A narrow width of the annular section provides good penetration of the catalyst stream by the feed to quickly and completely mix the catalyst and feed. A tapered conical section above the narrow annular section provides an extended region of gradually increasing flow area that controls downstream acceleration of the gas and catalyst mixture by permitting expansion and preventing back mixing over the initial stages of the cracking reaction. This arrangement improves the uniformity of gas and catalyst contacting while reducing the amount of steam or other dispersion gas required to achieve good catalyst and feed contact.

摘要： A process and apparatus for the separation of mixtures of liquids and finely divided suspended particles to produce a liquid product stream having a reduced concentration of finely divided suspended particles. The process and apparatus use a generally vertical separator vessel having a feed inlet distributor located in a lower locus of the vessel which directs the feed mixture in an upward direction in order to initially flow through a multiplicity of vertical and intersecting baffles located in the upper locus of the vessel and then to flow through a horizontal baffle having a multiplicity of holes to allow passage of the liquid and located above and adjacent to the vertical baffles.

摘要： An FCC process uses a tube sheet arrangement and a multiplicity of centrifugal separation devices in an FCC reactor to reduce the volume of the reactor vessel thereby minimizing uncontrolled reaction of feed hydrocarbons and the production of riser by-products. The separation arrangement encloses an upwardly directed outlet end of a ballistic separation device in a low volume disengaging vessel that transfers dilute catalyst and product vapors to a tube sheet arrangement of swirl tubes that removes catalyst and directs it downwardly into a stripper arrangement.
