Transfer trays for mass transfer columns in offshore use

Abstract

The invention describes a mass transfer column with at least one transfer tray via which the liquid is routed in essentially the horizontal direction and through which gas is routed in the vertical direction, the transfer tray being designed as a reverse flow tray and having a first means (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) and has another means for routing the liquid flow (guide weir) (5) and at least one other means for reducing the flow velocity (braking weir) (6). The transfer tray (2) is divided into sections (7) by the separating weir (4), guide weirs (5) and braking weirs (6). 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.
