Abstract: The distributor serves for a pairwise delivery of two liquids to a plurality of infeed sites in a reactor or in a column with a density of at least 50 sites per m2. The distributor has a pair of main passages that supply pairs of secondary passages with different liquid. Each pair of secondary passages is formed by a pair of upstanding side parts and an upstanding partition wall. Each side part has a base extending from a lower edge to the partition wall to define a secondary passage therewith for receiving liquid from a respective one of the main passages, and each base has a plurality of outlet apertures for the outflow of liquid from the respective secondary passage.

Abstract: The tray valve for a tray column includes an opening in a tray for a vapor passage and a valve body that is made to match the tray opening. The valve body consists of a top plate and vertically downwardly directed guide limbs arranged at the edge of the plate. The guide limbs have barbs for the anchoring of the valve body in the opening. The material and shape of the valve body are selected so that upon insertion of the valve body into the tray opening the top plate deforms in an arched manner while the guide limbs and barbs without deformation pass through the opening in a snap-fit manner. Weakened portions, in the form of grooves, slits or bores, can be provided in the top plate to facilitate upward arching of the top plate. Any deformation at the inserted valve body can be reversed, with the exception of a slight residual deformation, by an application of force onto the top plate.

Abstract: The liquid distributor includes a plurality of parallel spaced apart passages for receiving liquid, at least one carrier beam disposed transversely of and over the walls of the passages and at least one sheet metal plate slidably mounted on one of walls of the carrier beam in parallel relation to the wall. The walls of the carrier beam have hooks disposed in apertures of the passages and elevations disposed in recesses in the metal plate.

Abstract: The device is arranged in a process engineering column (10) and serves in particular for the guiding of liquid. This device includes at least two parts (1, 2) made of sheet metal and releasably connected to one another. A recess (12) is arranged in the one part, the sheet metal part (1) of a first kind, and an elevation (21) fitting into the recess is arranged in the other part, the sheet metal part (2) of a second kind. The two sheet metal parts are held in a secured position by a hook connection between the recess and the elevation. The recess and the elevation form a single pair or one pair among several and the sheet metal parts have planar regions lying on top of one another in the neighbourhood (120, 210) of the pair or of each pair respectively.

Abstract: The fluid inlet device for an apparatus, in particular for a column, has an inflow stub for the supply of a fluid which can be single phase or multi-phase. A distribution chamber adjoins the inflow stub and has guide lamellae arranged at at least one open side of the chamber by means of which a fluid can be distributed into the column on curved paths. Each guide lamella is mounted to the wall panels of the distribution chamber via plug connections. The stability of the construction is established by fixing one or all plug connections to the respective wall panel by welding, nut and bolt assemblies, snap fitting and/or wedges.

Abstract: The liquid distributor (1) for columns (6) has a main passage (2), a plurality of secondary passages (3) and an outflow system (5) of the main passage. The liquid (4) to be distributed can be fed into the secondary passages in accordance with a pre-set ratio by this outflow system. The outflow system (5) comprises apertures (20) in the side walls of the main passage and—associated with the secondary passages—guide elements (50) for the liquid (41) exiting through the apertures. The guide elements are designed with respect to a liquid guidance such that the liquid (42) can be led into the associated secondary passage.

Abstract: The guide member (1) for a liquid jet (30) to be deflected allows a liquid (3) after flowing out of a container (2) to be deflected onto a target (5; 7) which is located below the container. The deflecting takes place by means of a shaped material plate (10; 10a, 10b) which is arranged ahead of an outlet opening (20) of the container and which reshapes and further conducts the jet (30) in such a manner that the liquid is conveyed to the target at a lower end (17) of the shaped material plate. At the location ahead of the outlet opening (20), where the liquid jet (30) is incident onto the shaped material plate (10), a first and a second piece of surface (11 and 12 respectively) of the material plate form a mouth region (13) in which the first piece of surface (11) deflects the liquid (3) transversely with respect to the vertical, whereas the second piece of surface (12) is provided as a catcher for squirts. The first piece of surface merges into a channel (14) in which the liquid is guided downwards.

Abstract: The column contains a base (1) between an upper and a lower filler body section (8). With this base, liquid (9) is collected from the upper section in a buffer chamber (3) and collected liquid is distributed onto the lower section (8). Flues (2) serve as passages for a gas transport through the buffer chamber. Outlet openings (6) of the buffer chamber are arranged in vertical walls (20) of the flues and guide members (4) for the liquid to be distributed are arranged ahead of the outlet openings. Each outlet opening and its associated guide member are formed in such a manner that the liquid is incident onto a deflection surface (41) of the guide member as a largely free jet (90) unimpeded by a back pressure. The flue cross-section which is available for the gas transport is decreased by the guide members by at most 20%.

Abstract: The liquid distributor for columns has liquid outlet openings and fine distribution elements with a guide wall associated with them. A preselectable amount of liquid can be supplied into the associated fine distribution element via each outlet opening. A plate-like element communicating with the guide wall is arranged in each fine distribution element, with a communicating chain of capillary openings forming a distribution zone and drain-off zone between the edge of the element and the guide wall. This chain extends along a horizontal, closed curve.
