The invention relates to a column for carrying out thermal separations and/or chemical reactions, including a vertical cylindrical column outer wall that surrounds an inner chamber divided by at least one vertical separating wall into chambers, wherein the separating wall has at least two vertical separating wall elements that are arranged one above the other in the same plane, adjoin one another edge to edge, and are interconnected by at least one screw connection.

Column with at least one partition

An apparatus for mass transfer between a liquid and a gas inside a rotor having a packing. The liquid is introduced at a center of the rotor and driven outward through the packing by centrifugal force generated by rotation of the rotor, and 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. The packing inside the rotor is divided into individual packing segments that together form a circular disk. Each circular ring segment is formed by at least one structured packing formed of a plurality of superimposed woven, knitted, mesh or lattice structured surfaces composed of metal, in particular sheet-metal strips, or plastic or glass fibers, to which the axis of rotation of the rotor runs perpendicular.

Mass-transfer apparatus

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.

Mass-transfer machine

Efficient distillative separation of an at least three component mixture containing high boiler, medium boiler and low boiler components is accomplished by interposing a column having a stripping section and a rectifying section separated from each other by a horizontal impermeable dividing wall between conventional distillation columns. High efficiency and low capital cost is achieved.

Method and device for distillative separation of a three- or multi-component mixture

The invention relates to a mass transfer tray of a column with a liquid feed on the tray feed side and a liquid discharge on the opposite tray discharge side, and with multiple profile-shaped channels of a U-shaped cross section that are arranged in the tray between the feed and the discharge, parallel to one another and transversely in relation to the direction of liquid flow, and form between them gas passage slits which are covered over by elongated profile-shaped hoods, which have an inverted U-shaped cross section, wherein the side walls of the channels reach into the hoods, and so the channel side walls are covered over by the hood side walls by a height that is less than the height of the channel side walls and the height of the hood side walls, wherein the liquid flows alternately in opposite directions in the channels, and so in every second channel the liquid flows in one direction and in the channels lying in between the liquid flows in the opposite direction, and wherein the hoods are set higher than the channels in the case of the channels and hoods that are closer to the tray feed side, and consequently the heights over which they cover one another are less than in the case of the channels and hoods that are closer to the tray discharge side.

Mass transfer tray

A stacked packing column for heat and/or mass transfer has individual horizontal layers including a lower layer that has a greater density that initiates an accumulation, in particular flooding, and that is 1.5 to 10, preferably 2 to 3 times, greater than the density of an overlying upper layer. The upper layer forms oblique flow channels having lower sections that are more vertically aligned than respective upper sections. The lower sections of the flow channels have a larger cross section than the upper sections, and the sections of larger cross section open into the lower layer.

Packing arranged for an exchange of heat and/or material

A stacked packing for a heat-exchange or mass-transfer column has a horizontal upper packing part and a horizontal lower packing part below the upper part. This lower part is formed of a plurality of upright layers, some of which are of substantially greater density and have a greater surface area than others.

Stacked packing for heat exchange and mass transfer

A stacked packing for a heat-exchange or mass-transfer column has a horizontal packing part formed of a plurality of upright layers. Some of the layers of the lower part are of substantially greater density and have a greater surface area than others of the layers.

A column is described for carrying out reactive distillations in the presence of a heterogeneous particulate catalyst having an ordered packing or random packings which form intermediate spaces in the column interior, the quotient of the hydraulic diameter for the gas flow through the ordered packing or the random packings and the equivalent diameter of the catalyst particles being in the range from 2 to 20, preferably in the range from 5 to 10, in such a manner that the catalyst particles are introduced into the intermediate spaces, distributed and discharged loose under the action of gravity.

Device and method for carrying out heterogeneously-catalysed reactive distillations in particular for the production of pseudoionone

A fixed-bed reactor is described for carrying out reactions of fluid reaction mixtures in the presence of a particulate heterogeneous catalyst having a structured packing which forms interstices in the reactor interior, in which the quotient of the hydraulic diameter for the fluid flow through the structured packing and the equivalent diameter of the catalyst particles is in the range from 2 to 20, preferably in the range from 5 to 10, to such an extent that the catalyst particles are introduced into the interstices, loosely distributed and discharged under the action of gravity.

Heterogeneously catalyzed reactions and apparatus therefor

A partition for a packed column or a tray column which can carry out separation and/or chemical reactions has at least two partition elements disposed one above another and/or one alongside the other in the same plane, at least one plug and/or clamp connector connecting together the partition elements, and a sealing profile between an inner surface of the column and an edge of the partition elements turned toward the column inner surface. A fastening device is provided for the partition on the column inner surface. Lateral fastening parts of the partition carry inserts of the column and/or column trays. These fastening parts are rectangular profiles having upper sides extending horizontally in the column.

Partition assembly for packed or tray column

A hydraulically sealed crossflow mass transfer tray, separating columns which contain the hydraulically sealed crossflow mass transfer tray and the use of such separating columns for thermal separating processes.

Hydraulically sealed crossflow mass transfer tray

The invention relates to catalyst packing and a production process for catalyst packing in which a fabricated woven or knitted fabric in the form of continuous web goods is shaped to give a package by stacking a plurality of layers, and segments (S) are cut out of the package and assembled to give one or more course(s) which completely fill the reactor cross section. A reactor containing catalyst packing of this type is particularly suitable for catalytic reactions, preferably for hydrogenations, selective hydrogenations, selective oxidations or isomerizations.

Process for the production of catalyst packing, reactor containing catalyst packing, and the use thereof

A liquid distributor for packed or filled columns having a multiplicity of horizontal layers involved in heat transfer or mass transfer. At least one layer of the column has an increased density by comparison with the other layers and is designed specifically for flooding. The specific surface can be greater than the specific surface of the underlying layers by a factor of 1.5 to 10.

Liquid distributor and method for operating the same

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.
