20110285039 | DOWNCOMER FOR A GAS-LIQUID CONTACTING DEVICE - One exemplary embodiment can be a downcomer for a gas-liquid contacting device. The downcomer may include first and second spaced apart side walls, first and second end walls, a floor, and first and second opposing discharge walls. Generally, each end wall is coupled to a respective end of the first and second side walls. Typically, the floor is coupled to the side walls and end walls, and the floor has at least one section adapted for permitting the passage of liquid there-through. The first and second opposing discharge walls can be coupled to respective first and second side walls and having respective ends below the floor. | 11-24-2011 |
20120138175 | DISTRIBUTION TRAY, VESSEL, OR METHOD RELATING THERETO - 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. | 06-07-2012 |
20120241006 | PROCESS FOR CONTACTING ONE OR MORE FLUIDS AND A REACTOR RELATING THERETO - One exemplary embodiment can be a process for contacting one or more fluids in a vessel. The process may include passing one or more fluids into a chamber from an overhead tray and providing a conduit outside the chamber coupling a respective spillway to a respective hole for increasing contact time inside the conduit. Typically, the chamber forms one or more sidewalls forming at least one hole and the overhead tray forms at least one spillway. | 09-27-2012 |
20120304538 | CONFIGURATION OF CONTACTING ZONES IN VAPOR-LIQUID CONTACTING APPARATUSES - 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. | 12-06-2012 |
20130028799 | REACTOR VESSELS HAVING LIQUID DRAIN PIPES AND METHODS FOR DRAINING LIQUID FROM REACTOR INTERNALS - Embodiments of vessels including liquid drain pipes are provided, as are embodiments of methods for draining liquid from reactor internals. In one embodiment, the vessel includes a vessel shell, a tray mounted within the vessel shell and over which liquid accumulates up to a maximum liquid level during vessel operation, and a liquid drain pipe. The liquid drain pipe includes a tubular body attached to the tray and projecting upward therefrom, a vapor inlet formed in the tubular body above the maximum liquid level, a liquid inlet formed in the tubular body between the maximum liquid level and the tray, and a drainage port formed in the tubular body and positioned to direct accumulated liquid above the tray to an area below the tray to permit the drainage of accumulated liquid from over the tray during vessel shutdown. | 01-31-2013 |
20130062792 | CO-CURRENT VAPOR-LIQUID CONTACTING APPARATUSES FOR OFFSHORE PROCESSES - 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. | 03-14-2013 |
20130180595 | VESSEL, DISTRIBUTION TRAY, AND METHOD FOR PASSING ONE OR MORE FLUIDS - 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. | 07-18-2013 |
20150274614 | METHOD FOR RECOVERING ENTRAINED IONIC LIQUID FROM AN IONIC LIQUID IMMISCIBLE PHASE - 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. | 10-01-2015 |
