CA 2290091

A vapor-liquid contact tray (16) is provided with an upstream downcomer (46) and a downstream downcomer (48) which form a two-stage downcomer. The discharge outlet of the upstream downcomer (46) feeds liquid into the downstream downcomer (48) to help seal the discharge outlet (58) of the downstream downcomer (48) against vapor entry at lower liquid flow rates and to allow positioning of the discharge outlet (58) above the height of the weir on the underlying tray (16). Because the upstream downcomer (46) does not discharge liquid directly onto the underlying tray deck (40), the area of the tray deck (40) underlying the upstream downcomer (46) can contain vapor flow apertures (68) to increase the active area and mass transfer efficiency of the tray (16).

L'invention concerne un bac (16) de mise en contact vapeur-liquide doté d'un conduit de descente d'amont (46) et d'un conduit de descente d'aval (48) qui forment un conduit de descente à deux étages. La sortie d'évacuation de la descente d'amont (46) envoie du liquide dans le conduit de descente d'aval (48) pour isoler de manière étanche la sortie d'évacuation (58) du conduit de descente d'aval (48) et empêcher l'entrée de vapeur à des débits de liquide inférieurs et pour permettre le positionnement de la sortie d'évacuation (58) au dessus du déversoir situé sur le bac inférieur (16). Etant donné que le conduit de descente d'amont (46) n'évacue par le liquide directement sur le sommet du bac inférieur (40), la zone du sommet (40) du bac se trouvant au-dessous du conduit de descente d'amont (46) peut contenir des ouvertures (68) pour l'écoulement de vapeur de sorte que la surface active et l'efficacité de transfert de masse du bac (16) soit accrue.
