Title
(EN) A GAS-LIQUID CONTACTING APPARATUS
(FR) APPAREIL DE MISE EN CONTACT GAZ-LIQUIDE
Abstract
(EN)
A gas-liquid contacting apparatus is provided wherein the perforated trays (14, 15) are divided into portions (18 to 25) by a lattice-like pattern of downcomers (26) which deliver liquid to central regions of the tray portions immediately below them. An odd number, X, for example three parallel downcomers which are at right angles to an even number or X-1, for example two parallel downcomers are provided so that adjacent trays be turned at right angles so that the downcomers (26) of the upper tray (14) extend centrally between the downcomers of the lower tray (15). The downcomers (26) reduce stagnant liquid regions, distribute the liquid more evenly on the trays and allow longer flow paths to be provided on the trays.
(FR)
La présente invention se rapporte à un appareil de mise en contact gaz-liquide dans lequel des plateaux perforés (14, 15) sont divisés en parties (18 à 25) par un motif de type réseau de goulottes de descente (26) qui amènent un liquide jusqu'à des régions centrales des parties d'un plateau situées immédiatement en-dessous. Un nombre impair, X, par exemple trois goulottes de descente parallèles qui forment des angles droits avec un nombre pair ou X-1, par exemple deux goulottes de descente parallèles, sont disposées de sorte que des plateaux adjacents soient tournés à angles droits pour que les goulottes de descente (26) du plateau supérieur (14) s'étendent au centre des goulottes de descente du plateau inférieur (15). Ces goulottes de descente (26) réduisent les régions de liquide stagnant, répartissent le liquide de manière plus équilibrée sur les plateaux et permettent d'allonger les parcours d'écoulement devant être formés sur les plateaux.
