Title
(EN) STRUCTURED PACKING ASSEMBLY
(FR) ENSEMBLE D'EMBALLAGE STRUCTURE
Abstract
(EN)
Structured packing for mass-exchange or energy-exchange processes uses a tack of parallel, flat sheets (10, 10', 10'') forming flat channels therebetween. A number of tabs (12, 14) extends between adjacent pairs of sheets to form both bridges for fluid flow and spacers for structural rigidity of the packing. Some of the tabs serve predominantly to divert fluid over the entire surface of a given sheet to prevent so-called channeling, while other tabs are disposed to predominantly enhance fluid transfer between the adjacent sheets. Fluid communication between both sides of each sheet is facilitated due to slots (16) caused by the punching of the tabs. Preferably, the tabs or even entire sheets are perforated as well to facilitate fluid wetting of downward-faced portions of the tabs thus reducing 'dry zones' on the packing.
(FR)
L'invention se rapporte à un emballage structuré destiné aux processus d'échange de masse et d'échange d'énergie, qui utilise une pile de feuilles plates et parallèles (10, 10', 10'') délimitant entre elles des canaux plats. Un certain nombre de languettes (12, 14) fait saillie entre des paires adjacentes de feuilles de façon à former à la fois des ponts pour l'écoulement de fluide et des écarteurs assurant la rigidité structurale de l'emballage. Certaines de ces languettes servent principalement à dévier le fluide sur la totalité de la surface d'une feuille donnée de manière à empêcher ce que l'on convient d'appeler l'effet canal, tandis que d'autres languettes sont disposées de manière à accroître principalement le transfert de fluide entre les feuilles adjacentes. La communication fluide entre les deux faces de chaque feuille est facilitée par la présence de fentes (16) que l'on forme en découpant les languettes. De préférence, des découpes sont formées dans les languettes et même sur l'ensemble des feuilles dans le but de faciliter le mouillage par un fluide des faces des languettes tournées vers le bas, ce qui permet de réduire les 'zones sèches' sur l'emballage.
