    摘要： An improved de-entrainment device for use in distillation towers, especially vacuum distillation towers used for fractionating petroleum atmospheric resids is in the form of 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, 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 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.

    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： 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 and apparatus for dispensing fluid from a drop-on-demand (DOD) fluid dispenser. The method involves withdrawing fluid in the dispenser for a first duration of time, followed by a second duration of time during which the fluid is propelled toward the orifice of the dispenser. Following the period during which the fluid is propelled, there is a second withdrawing of the fluid into the dispenser. The duration of the propelling period is shorter than the duration of either the first withdrawing or the second withdrawing. The propelling of the fluid results in the extension of a small tongue of fluid from the meniscus of the fluid. The second withdrawing of the fluid results in a retraction of the meniscus into the passageway such that only the small tongue of fluid separates and is ejected from the dispenser.
