  • Publication number: 20160317960
    Abstract: Separation processes and separation apparatus are described. The process includes introducing a stream of liquid containing dispersed droplets of another liquid into a separation apparatus comprising a vessel having at least one mesh screen covering substantially all of the cross-section of the vessel. The mesh screen is periodically slightly moved so that the wires of the mesh screen contact the dispersed droplets and some of the dispersed droplets coalesce on the wires. The coalesced droplets rise or fall from the wires through the stream of the second liquid. The coalesced droplets are collected in a portion of the vessel. A stream of the second liquid having a reduced level of dispersed droplets is recovered.

  • Patent number: 9442186
    Abstract: Embodiments disclosed herein are directed to time-of-flight (TOF) systems, and methods for use therewith, that substantially reduce interference that the TOF system may cause to at least one other system that is configured to wirelessly receive and respond to IR light signals. Some such embodiments involve emitting IR light having a low frequency (LF) power envelope that is shaped to substantially reduce frequency content within at least one frequency range known to be used by at least one other system that may be in close proximity to the TOF system. Such embodiments can also involve detecting at least a portion of the emitted RF modulated IR light that has reflected off one or more objects. A TOF system can produce depth images in dependence on results of the detecting, as well as update an application in dependence on the depth images.

  • Publication number: 20160167012
    Abstract: An ionic liquid reactor unit and a process for controlling heat generation from an ionic liquid reactor unit. The ionic liquid reactor unit may include an external heat exchanger. The effluent from the reactor is separated in a separation zone allowing the hydrocarbon phase to transfer heat to a cooling fluid. The heat exchanger may be a tube-in-shell, a spiral plate heat exchanger, a hair pin heat exchanger. The heat exchanger accommodates the separation of the ionic liquid from the hydrocarbon phase, and may allow for the ion liquid to be drained.

  • Patent number: 9328296
    Abstract: A method for recovering entrained ionic liquid from an immiscible phase containing droplets of ionic liquid is described. The method includes contacting the immiscible phase containing the droplets of ionic liquid with a scrubbing ionic liquid phase in a scrubbing zone. The immiscible phase containing the droplets of ionic liquid has a first level of droplets of ionic liquid. At least a portion of the droplets of ionic liquid are transferred to the scrubbing ionic liquid phase to form a recovered ionic liquid phase comprising the scrubbing ionic liquid and the transferred portion of the droplets of ionic liquid and a second immiscible phase having a second level of droplets of ionic liquid lower than the first level. The second immiscible phase is separated from the recovered ionic liquid phase.

  • Publication number: 20140300700
    Abstract: An imager includes an emitter, an array of pixel elements, and driver logic. The emitter releases bursts of light pulses with pauses between bursts. Each element of the array has a finger gate biasable to attract charge to the surface, a reading node to collect the charge, and a transfer gate to admit such charge to the reading node and to deter such charge from being absorbed into the finger gate. The driver logic biases the finger gates with the modulated light pulses such that the finger gates of adjacent first and second elements cycle with unequal phase into and out of a charge-attracting state. To reduce the effects of ambient light on the imager, the driver logic is configured to bias the transfer gates so that the charge is admitted to the reading node only during the bursts and is prevented from reaching the reading node during the pauses.

  • Patent number: 8833742
    Abstract: An offshore co-current vapor-liquid contacting apparatus includes stages having contacting modules. Each contacting module includes a downcomer extending in a direction and has downcomer baffles distanced from each other in the direction to define downcomer cells within the downcomer. Each downcomer includes an outlet proximate to a co-current flow channel. A receiving pan extends substantially parallel to the downcomer and has receiving pan baffles distanced from each other in the direction to define receiving pan sections within the receiving pan. A vapor-liquid separation device has an inlet surface proximate to the co-current flow channel and an outlet surface above the receiving pan. Ducts are provided, with each duct having an upper end in fluid communication with a respective receiving pan section and a lower end in fluid communication with a selected downcomer cell in an immediately inferior stage.

  • Patent number: 8695953
    Abstract: One exemplary embodiment may be a distribution tray for a vessel. Generally, the distribution tray includes a member, a compartment, and an insert. The member can form a first side and a second side. Typically, the first side is adapted to receive a liquid thereon. Additionally, the member can form a plurality of openings. Usually, the compartment extends through the member with a first portion protruding from the first side and a second portion protruding from the second side, and is adapted to permit the passage of a fluid there-through. The insert may be positioned within the compartment to constrict and then expand the passage of the fluid there-through.

  • Patent number: 8608833
    Abstract: Methods are disclosed for the selective absorption of gas components based on differences in their gas phase and liquid phase resistances to mass transfer. The methods advantageously utilize a gas-liquid contacting apparatus having contacting stages with co-current flow channels that can provide contacting with increased liquid phase resistance to mass transfer, for example in the spray regime such that the liquid is effectively dispersed as small droplets into the gas phase.
