Claim:
A gas-liquid contact tray comprising a bubble area and a plurality of downcomers defining a plurality of downcomer openings, wherein each downcomer opening of said plurality of downcomer openings has opposing sides with said bubble area along each side of said opposing sides, wherein each downcomer opening of said plurality of downcomer openings is spaced in said bubble area, such that, when in use, a liquid enters each downcomer opening of said plurality of downcomer openings from opposite sides of each downcomer opening of said plurality of downcomer openings, wherein each side of said opposing sides of each downcomer opening of said plurality of downcomers is provided with at least two flow directing plates, wherein each flow directing plate of said at least two flow directing plates has an upper end and a lower end, wherein each upper end of each of said at least two flow directing plates extends above said bubble area and is inclined towards the direction of the liquid flowing towards said downcomer opening, wherein the lower ends of said at least two flow directing plates are substantially parallel with each other and extend vertically downward into the downcomer; wherein the downcomer opening is rectangular having a length longer than its width and wherein the upper end of the directing plates run parallel to the longitudinal side of the downcomer opening; and wherein a vertical anti-jump baffle is present along the longitudinal center line of the downcomer opening and wherein the flow directing plates are positioned at either side of the anti-jump baffle.
