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.

Structured cross-channel packing element with reduced material requirement

A plant for producing a structured cross-channel packing element. The structured cross-channel packing element comprises at least two adjacent layers made of expanded metal sheets each comprising periodic deformations. The plant comprises a stretching machine configured to cut and stretch a metal sheet to form one of a plurality of first expanded metal sheets, a calibration machine configured to roll the first expanded metal sheets to a desired thickness, a sheet storage unit configured to directly receive each of the first expanded metal sheets rolled in the calibration machine, a forming machine configured to form each of the first expanded metal sheets to form the expanded metal sheets comprising periodic deformations, and a stacking machine configured to stack the expanded metal sheets comprising periodic deformations to form the structured cross-channel packing element. The sheet storage unit is configured to release the first expanded metal sheets directly to the forming machine.

Plant and process for efficiently producing a structured cross-channel packing element

A structured 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 packing element comprises at least two layers of a grid comprising openings that are surrounded and separated from each other by separating elements. At least two of the 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. An average width of at least 50% of the separating elements between adjacent openings is at least 15 times a layer material thickness and is between 70% and 125% of an average hydraulic diameter of the adjacent openings.

A static devolatilization apparatus () for germ reduction of a fluid is disclosed. The apparatus () comprises a housing (), an inlet (), an outlet (), a fluid-contacting surface () comprising a biocide () embodied to reduce the germ count of the fluid (), wherein the fluid-contacting surface () is a fluid-contacting surface () of a static mixing element (). The present invention further relates to a process for reducing the germ count of a fluid containing germs (') using the apparatus () and also to the use of the apparatus () in the germ reduction of fuel oil, of food products, or water decontamination, preferably decontamination of waste water, industrial process water, or the treatment of drinking water.

Apparatus for germ reduction of a fluid and a process for use thereof

A liquid mixing collector includes first and second sump zones, a first and optionally a second liquid collection region, first and second interspersed sets of spaced apart liquid collection channels positioned in the first liquid collection region, the first and second sets of collection channels being associated with the first and second respective sump zones, wherein adjacent liquid collection channel sets are vertically displaced in parallel horizontal planes. The invention also relates to the process of using the collector within a heat or mass transfer column.

Liquid mixing collector and a method for its use

The use of a cross-passage packing made of a metal fabric relates to a method in which an exchange of material and/or of heat is carried out between a liquid stream and a gas or vapour stream. The fabric packing () used is composed of vertical layers () which consist of corrugated or pleated metal fabrics () which form flow passages (). The gas or vapour stream flows in the flow passages and the liquid stream flows on the metal fabric. The flow passages of adjacent layers cross in an open manner. The angle between crossing passages is lower than approximately 100&#xb0;. In this method, the fabric packing is acted on by a relatively small liquid loading. The metal fabric forms a carrier for the liquid stream that is largely free of holes or other apertures. Values for the liquid loading are selected in accordance with the relationship L/a&#x3c;10 l/mh, where L is the specific surface loading in volume units of the liquid per surface unit of the packing cross-section, and a is the specific surface which the metal fabric spans.

Mass transfer method using static packings

The mixer tube for low viscosity fluids contains plate-shaped elements which at one or at several points of the tube partially cover or block off its cross-section. The constrictions left free through the elements each comprise at least one gap-shaped region, with a longitudinal extent of this gap extending from tube wall to tube wall through the tube axis or from the tube wall through the tube axis to a second partial region. The gap subtends an angle with the tube axis in the range between about 20.degree. and 60.degree., preferably between 35.degree. and 45.degree.. A mixing path is provided after the constriction in the direction of flow. The fluid to be mixed can contain solid substances in suspension.
