  • Patent number: 10238997
    Abstract: A floating media filter including a filter housing with an influent conduit extending into the filter housing, the influent conduit having at least one outflow aperture positioned below an effluent outlet of the filter housing. A floating media is positioned in the filter housing and forms a media bed when the filter is in a filtration stage, the media bed having a lower surface and an upper surface defining a filtration zone between the lower and upper media bed surfaces during the filtration stage. A diffuser trough is positioned in the filter housing such that (i) the lower surface of the media bed, when the filter is in the filtration stage, is below an upper edge of the diffuser trough, and (ii) the outflow aperture of the influent conduit is positioned sufficiently close to a surface of the diffuser trough such that influent flow, during the filtration stage, is initially directed against and/or along the surface of the diffuser trough, and then redirected in a path into the media bed.

  • Patent number: 9835379
    Abstract: A cooling tower with a hot water distribution system includes a distribution lateral disposed above a hot water basin. The distribution lateral discharges fluid into the hot water basin, which in turn, releases the fluid through a plurality of orifices. As the fluid is released, it falls on heat-exchanging fill material that assists in increasing the cooling rate of the fluid. The distribution lateral is configured structurally to discharge the fluid through a plurality of outlets at one or more angles (as compared to the horizontal) into the hot water basins. In one embodiment, the outlets are arranged into one or more rows that extend along a substantial length of the distribution lateral. Discharging the fluid in this manner enhances and promotes a more even fluid flow within the hot water basin, which results in a more even fluid flow over and onto the fill material, thereby increasing thermal efficiency.

Generally, the first drier operates at a first condition to dry the fluid including at least one reactant and the second drier operates at a second condition during regeneration with a regenerant. The regenerant is displaced from the drier using a down-flow regenerant displacement assembly.

  • Patent number: 8235361
    Abstract: A structured packing for a reactor is formed from a metal sheet to promote heat and mass transfer near the wall of the reactor. The structured packing causes lateral flow of fluids flowing through the packing such that jet impingement of at least one reactor wall is promoted. The packing may be used in a cylindrical, annular or plate-type reactor, e.g., a catalytic reactor, or a heat exchanger.

  • Patent number: 8158073
    Abstract: A mass-exchange contact device is proposed, comprising an upper tray, contact element including a barbotage unit configured as an inner cap with strips tangently bent out, a lower tray, a casing including a ring-shaped descending limiter, windows circumferentially disposed on the casing's walls (lower row), orifices circumferentially disposed on the casing's walls (upper row) above the windows, a double-acting valve composed of an upper and lower plates fixedly attached to a distance rod, and a cover bushing disposed coaxially to and around the upper region of casing embracing the contact element. Embodiments comprise a number of rows of the proposed devices situated one above the other, and separated by multi-layer packing fittings. In catalytic distillation columns, the fittings can be filled with catalytic material. Alternatively, the fitting is substituted with a grating that supports a catalytic granular layer. The device allows improving operation, reliability, durability, reducing its weight and costs.

  • Patent number: 8142651
    Abstract: A tank has a side wall bounded by a top and a bottom. An axis extends vertically through the tank. An inlet line for water of a first condition extends through the top with a lower end at a lower extent of the tank. An outlet line for water of a second condition has a lower end within an intermediate extent of the tank. A dispenser at the lower end of the water inlet line has apertured legs extending radially within the tank. An oscillator within the tank above the dispenser is operatively coupled to the inlet line for mixing all of the water of a first condition entering the tank through the inlet line while thereafter forwarding all of the mixed water of a first condition to the dispenser.

  • Publication number: 20120032358
    Abstract: A device for the injection and mixing of steam into a fluid stream. The device is intended to be used in a substantially cylindrically-shaped primary conduit having a longitudinal axis and circular cross-section for carrying the fluid stream. The primary conduit is provided with an inlet for accepting the fluid stream and an outlet for discharging the fluid stream along the longitudinal axis. A secondary conduit is joined to the primary conduit for discharging steam within the fluid stream along the longitudinal axis. A biscuit element is provided of sintered tungsten having upstream and downstream circular faces sized to fit within the primary conduit along its interior wall having a geometric center coincident with the longitudinal axis and having a plurality of openings, each having a longitudinal axis parallel to the longitudinal axis of the primary conduit. Each opening is provided with a mixing element that induces a rotational angular velocity to the fluid stream passing therethrough.

  • Publication number: 20110309535
    Abstract: A packed column includes a regular packing (8) and a liquid distribution plate (5). The regular packing (8) is constructed by combining two or more hollow columns, and the hollow columns each have a cross section of circular shape, hexagonal shape or other shapes. The liquid distribution plate (5) has small holes under which liquid guide tubes (4) are connected. The liquid guide tubes (4) lead to all hollow columns of the packing (8). The liquid distribution plate (5) is horizontally installed above the regular packing (8) in a column body (2). Each gas guide plate (11) is made by rotating and twisting a rectangular plate and has several protrusions (12) on its side. The gas guide plates (11) are installed in the hollow columns of the regular packing (8) with the height slightly smaller than that of the hollow columns. A gas outlet (3) is located between the regular packing (8) and the liquid distribution plate (5).

  • Publication number: 20110305616
    Abstract: 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.
