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 feed device for a distillation tower has an annular, open-bottomed channel located around the periphery of the feed zone of the tower with an inner wall spaced from the inner curved wall of the tower and a top covering the channel to confer a generally inverted-U shape to the cross section of the channel. One or more tangential feed inlets are provided to admit a heated, mixed phase feed to the tower and direct the feed into and along the channel. One or more vapor scoops are provided for each feed inlet with the scoop(s) located on the inner wall of the channel at a sufficient distance along the channel from the inlet to permit cyclonic separation of vapor and liquid before the vapor in the feed from the inlet enters the scoop(s) and passes through a vapor exit port into the central core of the tower.

摘要： A combination of differently sized structured packings in the wash zone of distillation towers is provides advantages at high vapor rates. The use of a large crimp structured packing below a smaller crimp size structured packing is advantageous for vacuum crude unit service where fouling resistance is desirable and liquid entrainment into the wash zone is a problem at high vapor rates. The tower may be operated at high vapor flux rates or C 0.4 ft/sec or higher (0.12 m/sec). An unexpected characteristic of the combinations is that the entrainment increases only slowly with increasing vapor flux rate up to Cs values of at least 0.55 ft/sec (0.17 m.sec), as compared to other packings such as random packing, grid packing and combinations of grid packing with structured packing which allow entrainment to increase sharply at high vapor rates.

摘要： Systems and methods for determining the flow distribution of a fluid through a component with a sensing cable including an optical fiber sensor array aligned with a heating element disposed in the component. An excitation source is configured to propagate at least one heat pulse through the heating element along at least a portion of the sensing cable to affect an exchange of thermal energy between the heating element and the fluid exposed to the sensing cable. An optical signal is adapted to receive a signal from each of a plurality of sensor locations and measure a temperature profile corresponding to the heat pulse at the sensor locations. A control unit is configured to determine a flow of the fluid by determining one or more properties of the fluid exposed to the sensing cable at each of the plurality of sensor locations based on the temperature profile corresponding thereto. The present invention can be effective in accurate and high spatial resolution of flow distributions through vessel components, such as a particulate bed (such as a reactor catalyst bed), a wash bed including packing material, an absorbent bed, a structured bed, a filter, or the like.

摘要： A fluid separation packing that is useful as a packing material for distillation and fractionation columns or towers which provides for co-current liquid and vapor contact during the countercurrent separation process. The packing comprises a number of connected packing elements, suitably in the form of connected octagons, which have continuous side walls with an upper end and a lower end which terminates in a base with a vapor opening and a vapor tab above the opening. The side walls which define openings between adjacent packing elements are connected to one another to define a contacting volume above the base and there is a liquid slit on the side wall. The packing is also provided with liquid downcomers which have side walls with their upper portions within the openings between adjacent packing elements, and their lower portions extending below the packing element base. Downcomer ports through which liquid can flow are located proximate to the lower ends of the downcomers.

摘要： This invention is directed to a cyclonic vapor/liquid contacting device and distillation or related mass transfer or heat transfer processes employing its use, such as fluid catalytic cracking. Liquid feed is introduced near the floor of the cyclone via downcomer or plenum. Vapor enters through sieve holes in the bottom of the cyclonic device. Near the floor are angled tabs or vanes that impart a spin to the vapor rising up through the floor. The tabs or vanes mix the liquid and vapor. The liquid is then thrown toward the cyclone wall, where it exits through slots in the wall. A second set of tabs or vanes, located about in the middle of the cyclone, imparts additional spin to the vapor and entrained liquid rising through the cyclone. This improves liquid collection by the cyclone, especially in cases where a heavy liquid load dampens the spin action of the vapor in the base of the cyclone. In another embodiment, there is a non-spinning zone at the floor of the cyclone barrel which permits improved heat transfer between the liquid and vapor. If a non-spinning zone is used, the two sets of vanes or tabs are located at higher elevations within the barrel.
