ABSTRACT:
A liquid-vapor distribution device for use in two-phase stream concurrent down-flow vessels including:a plurality of BOXVLTs fabricated in form of self-supporting structures (beams) and tray panels when installed forms a tray which will be essentially leak free at the junctions and between the tray and the vessel wall;the horizontal self-supporting structure consisting of a bottom plate being perforated with at least one row of apertures of equal size, wherein each aperture is fitted with an elongated down-flow channel (downcomer) being in form of a tube or any other geometric shape with the same geometrical cross sectional shape as the apertures in the beam and the down-flow channel is provided with an inlet for the concurrent two-phase stream, and wherein at least two of the down-flow channels are fitted with a common riser cap being attached to and along at least one wall portion of each down-flow channel and mounted over and spaced apart the inlet of the down-flow channel.
