Abstract: A tray column in which a deentrainment element or packing is provided between the trays, is further equipped with a preseparator, especially in the form of plates, structural shapes, foils and/or at least one grate, spaced above a mass transfer tray and improving the efficiency by allowing trays to be closer together and preventing the migration of foam or bubble layers above the tray.

Abstract: A heat exchange or mass transfer column in which the packing bed is formed from individual packing layers wherein the sheet metal plates of the packing have different thicknesses.

Abstract: The invention relates to a liquid distributor for packed and/or filled columns, comprising individual, in particular horizontal layers involved in heat and/or material exchange. At least one layer of the column has a flooding, in particular for obtaining an increased density and for creating an accumulation of liquid and a specific surface for distributing the liquid. Said surface is greater than the surface of the overlying and underlying layers by a factor of 1.5 to 10, preferably by a factor of 2 to 3.

Abstract: The invention relates to a packing for heat- and material-exchange columns, with a number of approximately perpendicularly arranged corrugated plates (or strips), with the side surfaces thereof lying adjacent to each other. The ribs of the above lie very close to each other and run from top to bottom, in the approximate form of an arc, whereby the ribs of two adjacent plates cross each other and the ribs in the upper region of a plate are straight and inclined to the upper, in particular, horizontal plate edge and, in the lower region of the plate, run bent in the form of an arc.

Abstract: A column for performing thermal separations includes a vertical cylindrical outer column wall defining an inner volume which is subdivided by a separating wall into two halves filled with mass exchange packs, each of the mass packs has horizontal strip-like two rim guards, a lower guard is interrupted in the area of opposite corners of the respective mass exchange pack and an upper rim guard is a continuous flexible fabric strip.

Abstract: A column for performing thermal separations and/or chemical reactions with a vertical cylindrical outer column wall surrounding an inner volume, which is subdivided by a median vertical separating wall into two volume halves, wherein mass exchange packs are arranged, whereby an overheated liquid can be introduced in the column, whereby for the separation of the overheated liquid into liquid and vapor on the separating wall a box is mounted, wherein abuts a duct traversing the outer column wall and supplying the overheated liquid, whereby the box has a mist collector in its upper region and a liquid outlet in its lower region.

Abstract: A liquid distributor tray in heat exchange equipment, mass exchange equipment or reactors having roughly horizontal liquid distributor channels disposed in the tray, which channels, via openings, deliver the liquid downwards to fingers from which the liquid flows off and/or drips off. Below the channel base one pot or a plurality of pots are located which receive the liquid leaving the channel. The fingers, which are bent outwards, are attached or formed on at the lower edge of the pot wall. Openings are located above the fingers in the pot wall through which the liquid passes outwardly and flows down the outer wall of the pot to the fingers.
