Abrégé
(EN)
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 of liquid vertically downwardly, and wherein the central downcomer (34) is non-rotatably fixed at the fluid contact tray (10), and at least one conducting means (40) for transferring fluid collected in the annular channel (26) from the annular channel (26) to the central downcomer (34). This fluid contact tray (10) is in particular useable for offshore applications, such as for a fractionation column located on a FLNG or FPSO vessel.

一种用于分馏塔(1)的流体接触托盘(10),尤其是一种适合用于离岸分馏塔的蒸气‑液体接触托盘,包括:托盘甲板(12),其包括适合接触不同密度的两种流体(l、g)的主动质量传递表面(20),其中,主动质量传递表面(20)包括用于流体/气体(g)通过的一个或多个孔口(18),并且其中,在主动质量传递表面(20)上布置有将主动质量传递表面(20)分成至少两个分区(24‑1、24‑2、24‑3、24‑4)的至少两个至少部分地径向延伸的分离壁(22‑1、22‑2、22‑3、22‑4)和/或至少一个分离堰(42);环形沟槽(26),其适合于收集流体/液体(l),其布置在主动质量传递表面(20)的周边区域处并至少部分地包围质量传递表面(20);中心下降管(34),其用于收集和排出来自环形沟槽(26)的流体/液体(l),其中,中心下降管(34)具有中空体的形式,其在其底部区段中具有适合于液体竖直向下分布的开口(36),并且其中,中心下降管(34)被不可旋转地固定在流体接触托盘(10);以及,至少一个传导装置(40),其用于将收集在环形沟槽(26)中的流体从环形沟槽(26)传递至中心下降管(34)。该流体接触托盘(10)尤其可用于离岸应用,诸如用于位于FLGN或FPSO船舶上的分馏塔。
