摘要： A liquid distributor apparatus and method for the distribution of a high viscosity liquid into a process vessel generally free of entrapped gas bubbles. The distributor apparatus includes a distributor for the high viscosity liquid with openings on the top of the distributor to vent gas entrapped in the high viscosity liquid. The distributor apparatus includes a feed pipe to deliver smoothly and without gas entrapment a high viscosity liquid from the distributor directly onto a cup-like or conical surface of a distributor tube to form a downwardly flowing film on the exterior surface of the distributor tube and to deliver the high viscosity liquid to the top section of the process vessel without gas entrapment. The method comprises venting gas from a high viscosity liquid and slowing the downward velocity of the vented, high viscosity liquid into the process vessel to avoid further gas entrapment.

摘要： A vapor-liquid contact tray (16) is provided with an upstream downcomer (46) and a downstream downcomer (48) which form a two-stage downcomer. The discharge outlet (62) of the upstream downcomer (46) feeds liquid into the downstream downcomer (48) to help seal the discharge outlet (58) of the downstream downcomer (48) against vapor entry at lower liquid flow rates and to allow positioning of the discharge outlet (58) above the height of the weir (66) on the underlying tray (16). Because the upstream downcomer (46) does not discharge liquid directly onto the underlying tray deck (40), the area of the tray deck (40) underlying the upstream downcomer (46) can contain vapor flow apertures (68) to increase the active area and mass transfer efficiency of the tray (16).

摘要： A vapor-liquid contact tray and downcomer assembly is provided with ramps which serve to impart a horizontal directional flow to the liquid exiting the downcomer and/or the vapor passing through the tray. The downcomer includes a bottom plate which closes the outlet region of the downcomer and includes a plurality of ramps which redirect the downwardly flowing liquid to include a horizontal component in the direction of liquid flow across the underlying tray. The downcomer receiving area in the underlying tray can include valves having floating caps which shield the associated openings in the tray against liquid weeping and redirect the vertical movement of the vapor streams to a generally horizontal momentum.

摘要： A vapor-liquid contact tray is provided which includes a plurality of openings and associated fixed roof structures which redirect vapor flowing vertically upward through the openings to horizontal flow paths. Each fixed roof structure includes a generally planar deflector which overlies and is spaced above the associated opening in the tray. The deflector is joined to the tray by end plates connected at one end to the tray and at the other end to the deflector. In one embodiment the deflector is generally parallel to the tray and divides the vertically flowing vapor stream into roughly equal oppositely flowing vapor streams. In other embodiments, the deflector is inclined in relation to the tray to preferentially direct the vapor stream in one direction or to split the vapor stream into equal portions which are directed in the same general direction. The openings and deflectors are arranged to more uniformly push the vapor and hence the liquid into and through those areas of the tray where liquid stagnation and gradients are a problem. The fixed roof structures in the row of apertures closest to liquid receiving area at the inlet end of the tray are oriented so that the end plates shield the openings against entry of liquid leaving the receiving area. Louvre-type fixed roof structures are used in association with at least some of the openings in the first row so that more rapid frothing of the liquid can be achieved with reduced incidence of liquid weeping through openings in successive rows of openings.
摘要翻译： 提供了一种气 - 液接触托盘，其包括多个开口和相关联的固定屋顶结构，其将通过开口垂直向上流动的蒸汽重新定向到水平流动路径。 每个固定的屋顶结构包括大致平面的偏转器，其覆盖并且在盘的相关联的开口上方间隔开。 偏转器通过在一端连接到托盘并在另一端连接到偏转器的端板连接到托盘。 在一个实施例中，偏转器通常平行于托盘并将垂直流动的蒸气流分成大致相等的相反流动的蒸气流。 在其他实施例中，偏转器相对于托盘倾斜，以优先地将蒸气流引向一个方向，或者将蒸气流分解成相同的大致方向的相等部分。 开口和偏转器布置成更均匀地将蒸气推入并进入并通过托盘的那些区域，其中液体停滞和梯度是问题。 最靠近托盘入口端的液体接收区域的一排孔中的固定屋顶结构被定向成使得端板屏蔽开口以防止离开接收区域的液体进入。 与第一排中的至少一些开口相关联地使用罗盘式固定屋顶结构，使得可以通过在连续排开口中的开口的液体渗漏减少的入射而实现液体的更快速起泡。

摘要： A vapor-liquid contact tray and downcomer assembly is provided with louvres which serve to impart a horizontal directional flow to the liquid exiting the downcomer and/or the vapor passing through the tray. The downcomer includes a bottom plate which closes the outlet region of the downcomer and includes a plurality of louvres presenting generally vertical openings in the direction of liquid flow across the underlying tray. The downcomer receiving area in the underlying tray can include similar louvres. The louvres redirect the vertical momentum of the liquid and vapor streams to a generally horizontal momentum as the liquid exits the downcomer and as the vapor rises through the tray. In other embodiments, the louvres in either the bottom plate or the downcomer receiving area of the tray are replaced with apertures which do not block the vertical momentum of the stream passing through the apertures. An enhanced vapor-liquid active area on the tray results from the use of the louvres.
