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： 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.

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 mass transfer or heat exchange column is provided with a vapor distributor which circulates a vapor stream about the inner periphery of the column. The vapor stream is discharged from the distributor through an at least partially open bottom and, optionally, a plurality of spaced apart outlet ports in an inner annular wall of the distributor. A deflector extends upwardly along the inner annular wall to deflect the vapor stream away from a circumferential flow path along the inward face of the wall. The deflector may also extend outwardly under the flow channel to deflect, in a radially inward direction, vapor exiting the flow channel through the open bottom of the distributor.
