Abstract: A separations tray assembly for use in a fluid-fluid exchange column. The separations tray assembly is of the type where a first fluid, in a continuous phase, is directed across successive trays in a serpentine flow path. A second fluid, in a dispersed phase ascends through apertures in the tray thus inducing interaction and mass transfer with the first fluid. In accordance with one aspect of the present invention, the separations tray further includes a diffuser skirt, having apertures disposed therein, operatively coupled to a fluid channel. The diffuser skirt is operable to direct the first fluid to cover substantially an entire volumetric cross-flow window between successive separations trays and to induce stirring and mixing of the first fluid and the second fluid to effect efficient mass transfer.

Abstract: The invention describes a mass transfer column with at least one transfer tray via which liquid is routed in essentially the horizontal direction and through which gas is routed in the vertical direction. The transfer tray is designed as a reverse flow tray and a first separating weir (4) for changing the flow direction of the liquid flowing over the transfer tray by at least 90°, especially by roughly 180°. The transfer tray (2) is equipped with riser neck caps (3), at least one guide weir (5) for routing the liquid flow, and at least one braking weir (6) for reducing the flow velocity. The transfer tray (2) is divided into sections (7) by the separating weir (4), guide weirs (5), braking weirs (6), and column wall. The use of the riser neck caps (3) and weirs (4, 5, 6) with the resulting division of the transfer tray (2) into sections (7) ensures an almost uniform distribution of the liquid regardless of the tilt of the mass transfer column (1). The described mass transfer column (1) is thus suitable especially for use under offshore conditions.
