The gas separation device separates or captures a target gas component from a gas to be processed by: causing an absorbing liquid to flow down on a surface of a packing disposed inside a processing tank while supplying the gas to be processed containing the target gas component into the processing tank; bringing the absorbing liquid flowing down on the surface of the packing and the gas to be processed into gas-liquid contact; and thereby causing the absorbing liquid to absorb the target gas component contained in the gas to be processed. The packing includes at least one packing unit formed from multiple expanded metal plates, which are disposed vertically and arranged in parallel. Each expanded metal plate includes strands forming the openings which are arranged like stairs. Each strand is inclined to the vertical direction at an angle in a range from 48° to 73°.

A fluid solids contacting device comprising a vessel; a first grid assembly section which comprises a plurality of horizontal chords spaced horizontally apart from each other and a plurality of grid platforms inserted between the horizontal chords; wherein each horizontal chord comprises a structural member with sufficient mechanical strength to withstand fluidized forces in the vessel; a plurality of chairs attached to an inside surface of the vessel and spaced circumferentially apart to support the structural member; and wherein each structural member is supported on one or more of the plurality of chairs is provided.

Heat integrated distillation column for separating components in a fluid mixture. The heat integrated distillation column is provided with a stripper part (S), a rectifier part (R) and a compressor (2) between the stripper part (S) and the rectifier part (R). Furthermore, a heat exchange assembly for transferring heat between the stripper part (S) and the rectifier part (R), and a mass transfer assembly for condensation and vaporization in the heat integrated distillation column are provided. The stripper part (S), the rectifier part (R), or the stripper part (S) and rectifier part (R), comprise a channel formed by adjacent channel assemblies (6), each forming a structural part of the heat integrated distillation column and a functional part of the heat exchange assembly and of the mass transfer assembly. A plate (8) and a structured packing in the form of two or more corrugated plates (7) are provided.

A catalyst includes a gas-permeable textile sheet material made of noble-metal-containing wire having a three-dimensional secondary structure produced thereon. The secondary structure is a three-dimensional dent structure including dents arranged adjacent to each other in rows in two spatial directions. The dents are in the form of a hexagon. The dent structure is formed by self-organization in a denting process.

A wastewater or sludge treatment fixed film cross-flow distribution media corrugated sheet (84, 84′, 84″) and assemblies (118, 118′, 118″) thereof include corrugations (98, 98′, 98″), angled of about 10° to about 80° to the top and the bottom of the sheet and the assemblies. The sheet has a unitarily formed baffle (100, 100′, 100″) along at least a top portion of an exposed side of the sheet (96, 96′, 96″) or assemblies (130, 130′, 130″) exposed to denser wastewater or sludge outside of the assemblies than within the assemblies that is sufficient, when joined with either a like baffle (100, 100′, 100″) on a like sheet (84, 84′, 84″) or optional substantially planar interstitial sheets (132, 132′, 132″) adjacent the corrugated sheets, to substantially block air used in a sparging system from exiting or the denser wastewater or sludge being treated from entering the exposed side (96, 96′, 96″) of the sheet or the exposed side (130, 130′, 130″) of the assemblies. Beneficial biomass forming biofilm on the surfaces within the assemblies is controlled, effectively treating the wastewater or sludge.
