CA 2302468

A vapor-liquid contact tray (36) is provided with a tray deck (40) and an upstream downcomer (48) and a downstream downcomer (50) positioned at an opening (46) in the tray deck (40). The upstream downcomer (48) has at least two spaced apart legs (64) extending downwardly at a lower end thereof to carry liquid downwardly. The spacing between the legs (64) allows vapor to flow between the legs (64) so that the upstream downcomer (48) does not completely block the desired vapor flow pattern in the area of the downcomer (48). Each leg (64) includes a deflector (68) extending downwardly from a discharge outlet (66) to shield the discharged liquid from the vapor stream and to deflect the downward momentum of the liquid stream.

L'invention concerne un plateau de contact vapeur-liquide (36) comportant une plate-forme (40), un trop-plein en amont (48) et un trop-plein en aval (50) disposés à une ouverture (46) de la plate-forme (40). Le trop-plein en amont (48) comprend au moins deux jambes (64) espacées s'étendant vers le bas à une extrémité inférieure du trop-plein pour transporter des liquides vers le bas. L'espacement entre les jambes (64) permet un écoulement de vapeur entre elles (64) de sorte que le trop-plein en amont (48) ne bloque pas complètement le mode d'écoulement de vapeur voulu dans la zone du trop-plein (48). Chaque jambe (64) comprend un déflecteur (68) s'étendant vers le bas à partir d'un orifice d'évacuation (66) pour protéger le liquide évacué du flux de vapeur et pour dévier la force d'impulsion vers le bas du flux de liquide.
