摘要： The present invention relates to an improved design for use in fluid cracking processes, preferably used in either a fluid catalytic cracking ("FCC") process or a fluid coking process. In particular, the present invention relates to an apparatus and process for improving the separation and distributing spent catalyst and gases in a spent catalyst riser associated with a fluid cracking process, and most preferably for use in a spent catalyst riser associated with an FCC regenerator vessel. A novel catalyst distributor design and associated processes are presented herein which significantly improve combustion in the dense-phase fluidized catalyst bed of a regenerator and results in improved regenerator dense bed combustion and lower migration of oxygen into the regenerator overhead region. As a result, afterburn is significantly reduced in the regenerator and higher catalyst bed temperatures are achieved with significantly more uniform bed temperatures due to the improved combustion characteristics in the dense-phase fluidized catalyst bed.
摘要翻译：本发明涉及一种用于流体裂化过程的改进设计，优选用于流化催化裂化（“FCC”）工艺或流体焦化工艺。特别地，本发明涉及用于改进在与流体裂解过程相关联的废催化剂提升管中分离和分配废催化剂和气体的装置和方法，最优选用于与FCC再生器容器相关联的废催化剂提升管。本文提出了一种新型的催化剂分配器设计和相关的方法，其显着改善再生器的致密相流化催化剂床中的燃烧，并且导致改进的再生器致密床燃烧和较低的氧进入再生器塔顶区域的迁移。结果，由于在密相流化催化剂床中改善的燃烧特性，再生器中的后燃烧显着降低，并且由于改进的燃烧特性，床层温度更高，催化剂床温度显着提高。

摘要： An improved de-entrainment device for use in distillation towers, especially vacuum distillation towers used for fractionating petroleum atmospheric resids comprises a baffle which is to be located in the portion of the tower below the feed zone and at the top of the flash zone. The baffle is in the form of an apertured plate above the stripping zone and in its preferred form comprises number of radial fins or blades (13), resembling a static fan with openings between the fins to permit vapors from the lower portions of the tower to pass upwards through the baffle with a minimal pressure drop. The fins (fins) of the baffle are preferably oriented at an angle between 30° and 60° away from the incoming feed so that the incoming feed stream skims over the top edges of the fins (13).

摘要： A circulating fluid bed reactor such as that used in fluid coking processes has a circular dense bed reaction section above the reactor base where the fluidizing gas is injected and a plurality of frusto-conical baffles in the dense bed reaction section, each of which depends downwardly and radially inwards from the reactor wall to a lower, inner edge defining a central aperture. The baffles are preferably provided with downcomers which permit downward flow of solids and upward flow of gas through the baffles.

摘要： A de-entrainment device separates entrained liquid from vapor in a fluid stream that flows through a chimney tray in a distillation tower. The separated liquid is collected and shielded from the fluid stream to prevent re-entrainment of the liquid in the vapor flowing upward into the tower. The chimney tray includes risers with hats that have gutters to guide liquid toward the tray deck, channels to collect and drain liquid from the top of the hats to the tray deck, and baffles extending from the risers to shield the liquid collected on the tray deck from the vapor flow.

摘要： A method is provided for upgrading a hydrocarbon feed. The method may include contacting a hydrocarbon feed with a catalyst in a fluidized bed reactor; directing a portion of the catalyst from the fluidized bed reactor to a regeneration zone, such that the portion of the catalyst flows in a first direction through the regeneration zone; directing combustion air into the regeneration zone in a counter-flow direction to the first direction, wherein the combustion air is provided at rate of about 100.05% or less of the stoichiometric air requirement for combusting coke present on the portion of catalyst; regenerating the portion of the catalyst in the regeneration zone to produce regenerated catalyst; and directing a portion of the hydrocarbon feed to combine with the regenerated catalyst downstream of the regeneration zone and lift the regenerated catalyst back to the fluidized bed reactor.
