Cross flow trays in a mass transfer column are provided with downcomers having one or more walls that extend from a tray deck of one the cross flow trays to an elevation below a tray deck of an underlying one of the cross flow trays. The downcomer walls are connected to and provide structural support for the tray decks of the cross flow trays.

摘要:
Cross flow trays are provided with a support system. The support system interconnects the upper cross flow tray to a downcomer of the lower cross flow tray to provide support for the upper tray. In some aspects, the support system may also interconnect the downcomer of the lower cross flow tray to an upper tray of an underlying pair, providing additional support for the assembly. Such tray assemblies may facilitate easier installation without impeding the performance of the column.
摘要:
A flow distributor for a liquid descending in a vertically elongated mass transfer column, a mass transfer column employing the same, and a method of treating a fluid stream in the mass transfer column is provided. The flow distributor includes a central distribution member for passing liquid to a plurality of outwardly extending side arm members, which, in turn, feed the liquid into a plurality of distribution troughs located below the elongated side members. The distribution troughs, which may be oriented substantially perpendicularly or substantially parallel to the elongated side members, include a bed of packing material disposed therein. Use of such distributors in vapor-liquid or liquid-liquid columns results in more uniform horizontal distribution of the liquid across the diameter of the column.

A liquid distributor is provided for receiving and distributing a liquid stream in a mass transfer column. The liquid distributor has a plurality of elongated primary troughs and a plurality of secondary troughs that are positioned adjacent the primary troughs at a location to receive at least some of the individual primary discharge streams from the primary troughs. Splash baffles are spaced a preselected distance from liquid discharge holes in the side walls of the secondary troughs to receive at least some of the individual secondary discharge streams and cause a lateral spreading thereof as the individual second discharge streams descend along the splash baffles and drip from lower edges thereof.
