    Abstract: A distributor system (18, 36) for uniformly directing vapor and liquid across the surface of a fixed bed (42) of solids in a downflow reactor (14). A first array of open-ended downpipes (33) has a plurality of vertically spaced elevations of holes (39, 40) above the level of a distributor tray (18). A second array of the downpipes (34) has at least one elevation of holes (41) but no elevation of holes as the same height as the lowermost elevations of holes (40) in the first array (33). The absence of holes causes the liquid flow rate through the distributor tray (18) at a given height to be reduced when that liquid height falls below the elevation of holes (39) second from the bottom in the first array (33).

    Abstract: A process for solvent dewaxing petroleum feedstock to separate crystallized wax from lubricant oil by filtration of a wax/oil/solvent mixture. A waxy oil is fed through line (1) and is mixed with solvent fed through line (2) from a solvent recovery section. The wax/oil/solvent mixture is fed to heat exchanger (3) and heated to ensure that all wax crystals are dissolved in true solution. This warm mixture is then fed through line (4) to heat exchanger (5) in which it is cooled.

    Abstract: A process for the rejuvenative catalytic oxidation of offensive substances, such as cyanides, sulfides, sulfites, thiosulfates, mercaptans, disulfides, ammonia and mixtures thereof, contained in waste water is provided. The process comprises adding to the waste water a low concentration of a metal compound and then passing the treated waste water along with a source of oxygen over an adsorbent material to catalytically oxidize the offensive substances contained in the waste water. The process reduces the catalytic impact of the loss of metal from the adsorbent material due to leaching and allows the catalyst to be rejuvenated and allows recovery from process upsets in the treating system without unit shutdown and catalyst replacement. An example of the catalytic support is activated carbon and an example of the metal is copper.
