Abstract
A fluid contact tray (10) for a fractionation column (1), in particular a vapor-liquid contact tray suitable for the use in an offshore fractionation column, comprises: ⋅a tray deck (12) comprising an active mass transfer surface (20) suitable for contacting two fluids (l, g) of different densities, wherein the active mass transfer surface (20) comprises one or more orifices (18) for the passage of a fluid/gas (g), and wherein at least two at least partially radially extending separation walls (22-1, 22-2, 22-3, 22-4) and/or at least one separation weir (42) are arranged on the active mass transfer surface (20), which divides the active mass transfer surface (20) into at least two sections (24-1, 24-2, 24-3, 24-4), ⋅an annular channel (26) suitable for collecting fluids/liquids (l), which is arranged at the peripheral area of the active mass transfer surface (20) and at least partially embraces the mass transfer surface (20), ⋅a central downcomer (34) for collecting and discharging a fluid/liquid (l) from the annular channel (26), wherein the central downcomer (34) has the form of a hollow body with an opening (36) in the bottom section thereof being suitable for the distribution o…
