STRUCTURED NOZZLE ELEMENT MANUFACTURED WITH REDUCED MATERIAL CONSUMPTION Russian patent published in 2023 - IPC B01J19/32 

FIELD: structured packing elements.

SUBSTANCE: invention relates to a structured packing element for a column intended for mass transfer and/or heat exchange between heavy and light fluid phases. In this case, the structured packing element includes at least two layers of mesh, including holes, which are surrounded and separated from each other by separating elements. At least two of at least two layers are located in the longitudinal direction parallel and in contact with each other so that an open space is formed between them, extending from one end to the opposite end of at least two layers, along which can at least one of the heavy and light fluid phases must occur. Moreover, the average width of at least 50% of the separating elements between adjacent holes is at least 15 times greater than the thickness of the layer material and ranges from 70% to 125% of the average hydraulic diameter of adjacent holes. The maximum distance between at least two of the at least two layers, measured in a plane perpendicular to the longitudinal direction, is at least 4 times the average width of the separating elements.

EFFECT: creation of a structured packed element characterized by high mass transfer efficiency for a given capacity, or high capacity for a given mass transfer efficiency, or lower weight for a given mass transfer efficiency.
