The present invention relates to a structured packing element (21) having the shape of a rectangular flat plate, provided with slots (23) and recesses (22). The slots (23) are intended for assembly by interlocking the structured packing elements together in order to form the structured packing. The recesses (22) are provided in order to form channels within the structured packing.

The present invention also relates to a packing structure obtained by assembling such packing elements (21), the use of such a packing for an operation of bringing a gas and a catalyst into contact, and a manufacturing process of such a structured packing.

The present invention also relates to a packing structure obtained by assembling packing elements having a spiral helix shape.

The present invention also relates to the use of a structured packing composed of packing structure for an operation for bringing a gas into contact with a catalyst, and a process for manufacturing such a structured packing.

In an apparatus for mass transfer between a liquid and a gas inside a rotor, the liquid is supplied to a center of the rotor and is driven outward by centrifugal force generated by rotation of the rotor, the gas surrounding the rotor is forced inward through the rotor by a pressure of the gas, counter to the liquid flow in the rotor, and the rotor has a plurality of passages lying in the plane of the rotor that begin at a center of the rotor and terminate at an outer circumference of the rotor. The passages are each filled with a packing that increases the area of contact between the liquid and the gas.

The invention relates to a packing assembly for a material exchange column, comprising at least one structured packing plate and a container in which the at least one structured packing plate is arranged. The at least one structured packing plate has packing packets. Each packing packet has interconnected packing sheets. The packing sheets are corrugated and have corrugation peaks and corrugation valleys. Adjacent packing sheets contact each other at the corrugation peaks. Additional corrugated packing sheets are added between the packing packets such that the at least one packing plate is pretensioned against the container in a radial direction thereof. Both the corrugated packing sheets of the packing packets as well as the additional corrugated packing sheet added between the packing packets are arranged solely on a common preferred plane or parallel thereto.

An annular divided wall column for the cryogenic rectification of air or constituents of air is provided. The annular divided wall column includes a first annular column wall and a second annular column wall disposed within the first annular column wall to define an annulus column region and an interior core column region. The present annular divided wall column further includes structured packing elements disposed within at least the annulus column region as well as a ring-shaped cantilevered collector; and a ring-shaped distributor disposed in the annulus column region above or below the plurality of structured packing elements. The thermal expansion and contraction of the second annular column wall in a radial direction and in an axial direction is independent of the thermal expansion and contraction of the first annular column wall in the radial and axial directions.

A device for heat, mass, and chemical exchange and interaction between gases and liquids. Nozzles feed the gas at angles in different directions to form a gas-liquid mix, swirls, and/or foam above an array of such nozzles.

A device comprises a structure (100.0) for conducting a first fluid, the structure (100.0) having in addition an interface for conducting a second fluid, wherein the first fluid can be brought into contact with the second fluid at the interface of the structure. A flow interrupter (120.0) for interrupting a flow of the second fluid is situated at the interface of the structure (100.0).

The present invention relates to a packing element for a structured packing including at least two adjacent corrugated sheets, wherein each of the corrugated sheets has a plurality of alternately oriented peaks and troughs, wherein adjacent corrugated sheets are oriented such that the corrugations of the adjacent corrugated sheets intersect in crisscross fashion with the corrugations of the corrugated sheets extending obliquely relative to the vertical direction, wherein each corrugated sheet contacts each of the adjacent corrugated sheets at points of intersection between the corrugations of the corrugated sheet and those of the adjacent corrugated sheets, wherein all corrugated sheets are tied together by means of at least one rod, wherein the at least one rod penetrates the corrugated sheets perpendicularly to the longitudinal section of the corrugated sheets, wherein on the at least one rod before the first corrugated sheet of the packing element and/or after the last corrugated sheet of the packing element at least one mounting clip is provided for fixing the corrugated sheets on the rod, wherein the mounting clip has a central part forming a coupling portion for coupling the mounting clip to the rod and two opposing lateral parts forming a clamping portion for a clamping engagement with the corrugated sheet, wherein the lateral parts are connected with the central part and angled with respect to the central part.
