Abstract

L'invention concerne une colonne à plateaux améliorée convenant comme laveur de gaz. Cette colonne à plateaux comporte au moins deux zones et chaque zone comporte au moins un plateau perforé ou grillagé sans déversoir ni conduit de descente, avec un taux de surface de passage Fc de l'ordre de 0,30 à 0,60, et un distributeur d'alimentation en liquide à sa partie supérieure. Le taux de surface de passage du plateau de chaque zone, respectivement, augmente de la zone supérieure à la zone inférieure. Le distributeur d'alimentation en liquide, excepté pour la zone supérieure, est de préférence muni d'une pluralité d'ajutages de telle façon que le liquide soit pulvérisé dans une zone centrale du plateau, cette zone représentant environ 10 % à 50 % de la surface totale du plateau. Application à l'amélioration du rendement d'une colonne de lavage des gaz.The invention relates to an improved tray column suitable as a gas scrubber. This column with plates comprises at least two zones and each zone comprises at least one perforated or meshed plate without overflow or downpipe, with a rate of passage surface Fc of the order of 0.30 to 0.60, and a liquid supply distributor at its upper part. The rate of the area of passage of the tray of each zone, respectively, increases from the upper zone to the lower zone. The liquid supply distributor, except for the upper zone, is preferably provided with a plurality of nozzles such that the liquid is sprayed into a central zone of the tray, this zone constituting about 10% to 50% of the volume. the total surface of the board. Application to improving the efficiency of a gas washing column.
