摘要： 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.

摘要： One exemplary embodiment can be a method passing one or more fluids through a compartment. The method may include collecting a liquid on a tray, passing a vapor through the compartment, and mixing the vapor with the liquid entering the compartment via at least one aperture to impart swirling to the vapor and liquid exiting the compartment. Also, the compartment can include or consist of an interior wall and an exterior wall, and generally the compartment at least partially forms rifling on the interior wall.

摘要： Vapor-liquid contacting apparatuses comprising a primary contacting zone and a secondary contacting zone are disclosed. A representative secondary contacting zone is a secondary absorption zone, such as a finishing zone for subsequent contacting of the vapor effluent from the primary contacting zone to further remove impurities and achieve a desired purity of purified gas exiting the secondary absorption zone. The secondary contacting zone is disposed below the primary contacting zone, such that the secondary contacting zone, which must operate efficiently in removing generally trace amounts of remaining impurities, is more protected from movement than the more elevated, primary or initial contacting stages for bulk impurity removal. The apparatuses are therefore especially beneficial in offshore applications where they are subjected to rocking.

摘要： De-entrainment devices for effectively removing entrained liquid from a vapor stream are disclosed. These de-entrainment devices are effective in distillation columns and other apparatuses comprising vapor-liquid contacting devices. Particular representative applications for these de-entrainment devices are in distillation (or fractionation) columns having co-current contacting modules, in which liquid and vapor enter into co-current flow channels of the modules. The de-entrainment devices can be used, for example, with non-parallel contacting stages or other types of high capacity trays.

摘要： A phase-based TOF system preferably generates an optical waveform with fast rise and fall times, to enhance modulation contrast, notwithstanding there will be many high order harmonics. The system is preferably operated with an odd number of phases, to reduce system bias error due to the higher order harmonics, while maintaining good modulation contrast, without unduly increasing system memory requirements. Preferably the system can dynamically calibrate (and compensate for) higher order harmonics in the TOF generated optical energy waveform, over time and temperature. Within the optical energy transmission channel, or within the optical energy detection channel, detection amplifier gain may be modified, and/or detector signal integration time may be varied, and/or digital values may be employed to implement calibration and error reduction The resultant TOF system can operate with improved phase-vs-distance characteristics, with reduced calibration requirements.
