The present technique presents a structured packing module 100 for a gas phase reactor 2, the structured packing module 100 comprising a structured packing 1 having a central axis 5x extending along a longitudinal direction, and may further comprise an inner tube 5 extending coaxially with the structured packing and along the longitudinal direction. The structured packing 1 includes a plurality of corrugated sheets 10, 20, 30, each arranged circumferentially around the central axis 5x and having a first end 101 and a second end 102 spaced apart from each other along the longitudinal direction. Each corrugated sheet 10, 20, 30 includes corrugations 9 extending between the first end 101 and the second end 102 and disposed at an acute angle A greater than or equal to 5 degree and less than or equal to 30 degree with respect to a line 5y parallel to the central axis 5x. The corrugated sheets 10, 20, 30 are arranged to radially overlap with each other such that the corrugations 9 of adjacently disposed corrugated sheets 10, 20, 30 are arranged in a crisscross relationship. The structured packing module 100 includes a gas flow path 40 comprising at least one inter-sheet gas flow path 42 defined between the adjacently disposed corrugated sheets 10, 20, 30.

A structured packing module for crossflow applications is provided and includes a plurality of corrugated structured packing sheets positioned in an upright, parallel relationship to each other. The corrugations of adjacent structured packing sheets are in contact with each other and extend at a crossing angle. Apertures and raised ridges may be positioned on sidewalls of the corrugations. The structured packing module may be used in a crossflow contactor, such as in a process for removing carbon dioxide from air.

The contacting device for countercurrent contacting of fluid streams and having a first pair of intersecting grids of spaced-apart and parallel deflector blades and a second pair of intersecting grids of spaced-apart and parallel deflector blades. The deflector blades in each one of the grids are interleaved with the deflector blades in the paired intersecting grid and may have uncut side portions that join them together along a transverse strip where the deflector blades cross each other and cut side portions that extend from the uncut side portions to the ends of the deflector blades. At least some of the deflector blades have directional tabs and associated openings to allow portions of the fluid streams to pass through the deflector blades to facilitate mixing of the fluid streams.

The invention relates to a catalyst filling, comprising a first layer of a planar catalyst material and a second layer of a planar catalyst material lying over said first layer, wherein the catalyst material of the first layer comprises at least two plates, which butt against each other to form an abutment edge in each case, wherein the catalyst material of the second layer comprises at least two plates, which butt against each other to form an abutment edge in each case, and wherein the plates of the second layer are designed and/or arranged relative to the plates of the first layer in such a way that the abutment edge or abutment edges of the second layer are not aligned with the abutment edge or abutment edges of the first layer.
