The invention relates to a lining (10) intended to be positioned inside a chamber (1) to promote contact between fluids circulating inside said chamber, said lining comprising a plurality of separate criss-crossing strips (12): —first strips (12.1i) parallel to a first direction (D1) and defining a plurality of first planes spaced apart from each other, —second strips (12.2i) parallel to a second direction (D2) forming an angle with the first direction (D1) and defining a plurality of second planes spaced apart from each other. In each first plane, a free space separates two first adjacent strips I a direction perpendicular to the first direction and receives a second strip, the first and second strips being secured together. Each separate strip of at least one stage is perforated (12) and selected from a strip made from a stamped metal sheet and a strip made from an expanded metal sheet.

A gas-solid contacting system (100) with structured packing (108) is disclosed. The structured packing (108) comprises a gas header (102) with an inlet to receive a gas. A plurality of vertically aligned tubes (104) is fluidically connected to the gas header (102), wherein each vertically aligned tube (104) comprises openings (180)to distribute the gas at different heights in a radial direction. A structured packing element (106) is arranged on each vertically aligned tube (104), wherein the structured packing element (106) comprises one or more plates attached to the vertically aligned tube (104) to create a convoluted 3-dimensional flow path for smooth flow and radial distribution of a solid particulate stream.

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 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.

A packing module for use in a mass transfer column has a plurality of packing elements positioned in an upright, parallel relationship to each other. Each packing element has a plurality of side-by-side and parallel longitudinal rows of arched outer rib elements that are connected at opposite ends to spaced apart side strips. The outer rib elements project outwardly in opposite directions from the side strips. In an upper edge region and a lower edge region at least one of the side strips in each longitudinal row converges toward the other side strip. The convergence of the side strips causes a reduction in length and outward projection of the outer rib elements that are connected at opposite ends to the converging side strips. The longitudinal rows of outer rib elements in adjacent packing elements are arranged in crisscrossing relationship to each other.

The present invention relates to a packing structure made up of an ordered arrangement of bundles of tubes (1). For each tube bundle, tubes (1) are oriented in the four directions formed by the diagonals of a rectangular parallelepiped having one dimension larger than the others.
