Abstract:
The present invention relates to a packing structure made up of an ordered arrangement of bundles of tubes (1). For each tube bundle, tubes (1) are oriented in the four directions formed by the diagonals of a rectangular parallelepiped having one dimension larger than the others.
Abstract:
The present invention provides a vapor-liquid contact device for use in a distillation column and method incorporating the use of such a vapor-liquid contact device. The vapor-liquid contact device has arrays of elongated strips to support a falling film of a liquid and contact of a vapor with the film. The strips are supported in a structure having top and bottom sections connected to opposite ends of the strips. The top sections have apertures in registry with the strips so that liquid distributed to the top section seeps out of the apertures to initiate formation of the falling film. Openings are provided at the top and bottom sections, so that a vapor is able to pass through the support structure to contact the falling film to effect contact between the liquid and the vapor. Liquid distributors are associated with the top section to distribute the liquid to the apertures.
Abstract:
There is provided a liquid-gas contact device which has a liquid distributor (2) provided in the upper portion of the device, a liquid collector (3) provided in the lower portion of the device and an internal structure between the liquid distributor (2) and the liquid collector (3) which defines a plurality of flow paths. The liquid-gas-contact device includes a column packing (5) constituting the internal structure made of a plurality of column packing constituting elements (6) each of which extends vertically in parallel to each other in a non-contact state and in a non-contact state with an inner wall of the device, a plurality of adaptors (4) connecting the liquid distributor (2) with the column packing (5) for supplying liquid from the liquid distributor (2) to the column packing (5), and a plurality of collectors (7) connecting the column packing (5) with the liquid collector (3) for supplying liquid from the column packing (5) to the liquid collector (3).
Abstract:
An internal static mixing system such as a disperser of mesh wire or expanded metal co-knit with a multi filament material selected from inert polymers, catalytic polymers, catalytic metals or mixtures in combination with a vertical reactor having a reaction zone and the disperser disposed in said reaction zone, particularly for carrying out paraffin alkylation using acid catalyst is disclosed. The wire mesh provides the structural integrity of the system as well as the open space required in reactors for the movement of vapors and liquids though the system. The disperser may be in sheets, bundles or bales or positioned within a frame.
Abstract:
A random packing element comprising a transfer element, wherein said transfer element has an edge, said edge being configured with a plurality of alternating depressions and extensions, said extensions being substantially curved in shape, said transfer element having a first surface and a second surface, said first surface preferably including a plurality of protuberances.
Abstract:
A structural element for use as a carrier body in a catalytic process, condenser body or filter is formed by unwinding a foil from a roll, forming staggered cuts in the foil, and stretching the foil transversely to convert the cuts into hexagonal apertures interconnected by webs which become twisted to provide the sheet with a depth dimension. The sheet can be cut to length and layered with other like sheets in a flat or rolled form.
Abstract:
Process tower vapor-liquid contact method and apparatus comprising stacks of corrugated contact plates having perforated lamella disposed therebetween. The corrugated plates are disposed in face-to-face contact with respective corrugations inclined to the horizontal and separated one from the other by a perforated sheet. The assembly affords optimal pressure drop characteristics, surficial area, vapor passage area, and vapor-liquid distribution characteristics with maximum efficiency. The sandwiched plate separating adjacent corrugated contact plates greatly increases the mass and heat transfer between the liquid and vapor phases passing thereacross by effectively segregating opposed corrugated channels and establishing a plurality of vapor-liquid contact areas positioned for engaging both vapor and liquid flow in opposed directions through the oppositely inclined corrugations of adjacent plates. In this manner the notional plane is defined between stacks of inclined corrugated contact plates and provided in a configuration providing multiple mass and heat transfer points between adjacent corrugations and the flows directed therethrough wherein the vapor-liquid contact is maximized with a minimum of pressure drop.
Abstract:
A gas-liquid contact grid is formed of grid members which are connected together by connector members. Each grid member has an elongated upstanding web and laterally extending upper and lower flanges which are discontinuously formed of flange segments which extend alternately in opposite lateral directions from the web. Openings are provided in the upper and lower flanges. The web has interruptions which are located below and in vertical alignment with the ends of the flange segments to cause downwardly flowing liquid to spread longitudinally along the web. The flange segments on adjacent grid members do not extend toward each other to constrict the flow of ascending gases.The connector members are slotted and they extend through aligned holes in the webs of the grid members. During assembly, a connector member is inserted through the holes, and then it is rotated so that the slots engage the web to retain the connector members and the grid members in interengaged relationship.
Abstract:
A structured cross-channel packing element for a column for at least one of mass transfer and heat exchange between a heavy fluid phase and a light fluid phase. The structured cross-channel packing element comprises at least two adjacent layers made of expanded metal sheets each comprising openings that are surrounded and separated from each other by separating elements. At least two of layers are arranged in a longitudinal direction parallel and in touching contact with each other such that an open space extending from one end to an opposite end of the layers is provided between the layers such that at least one of the heavy fluid phase and the light fluid phase may flow therethrough. A ratio between an average width of at least 50% of the separating elements between adjacent ones of the openings and a sheet material thickness is at least 15.
