  • Patent number: 10703700
    Abstract: A liquid phase selective oxidation process is described. The process involves the partial oxidation of alkanes to partially oxidized products. A lower alkane, a solvent, and a soluble metal catalyst are contacted in the presence of an oxidizing agent in a reaction zone under partial oxidation conditions to produce the partially oxidized products. The partially oxidized products include one or more of lower alkyl alcohols, lower alkyl ketones, and lower alkyl acetates. The soluble metal catalyst is a soluble metal salt of cobalt, manganese, chromium, titanium, copper, nickel, vanadium, iron, molybdenum, tin, cerium, zirconium, or combinations thereof, and the promoter comprises a bromine source, an imide source, or combinations thereof.

  • Patent number: 10703990
    Abstract: A process is disclosed for using an iron oxide and alumina catalyst with no more than more than about 55 wt % of the alumina in the diaspore phase or in the alpha phase in SHC. Alpha alumina is less effective catalyst component for slurry hydrocracking in terms of TIOR conversion. Drying procedures should avoid more than about 51 wt % of the alumina change to the alpha phase. The SHC catalyst is for converting heavy hydrocarbon feed into lighter hydrocarbon products.

  • Patent number: 10703691
    Abstract: Process for producing para-xylene are described. The processes utilize a dual raffinate approach. Two raffinate streams from the adsorption separation unit are fed to the raffinate distillation column independently to take advantage of the differing desorbent concentrations in the two raffinate streams. The process yields significant reboiler duty savings and a reduction in overall fired fuel needed.

  • Patent number: 10695711
    Abstract: Adsorbers have many purposes in chemical, gas-processing, and petrochemical plants. Adsorbers may be used to remove components from gas streams. Adsorbers may be subjected to various issues, including but not limited to moisture breakthrough, spent catalyst, too high or too low pressure drop, over or under heating, over or under cooling, too high or too low flow rates, which can affect their performance or result in a shutdown of the adsorbers. Monitoring the adsorbers and the processes using adsorbers may be performed to determine if the adsorbent bed is reaching saturation, other problems are occurring, or if equipment failures are imminent. Monitoring also helps to predict behavior or problems in different adsorbers used in the same plant or in other plants and/or processes.

  • Patent number: 10688407
    Abstract: Process and apparatus ensure high on-stream reliability of a complex that requires a heat pump which is using a compound having a high boiling point, such as xylenes. When the compressor is shutdown, it can be isolated from the distillation column and receiver while the column is allowed to continue to operate with an auxiliary reboiler for constant heat input. The heat pump can be started up and heated to the normal process temperature, so that when the heavy vapor is charged to the heat pump, it does not immediately condense into liquid, causing damage to the compressor.

  • Patent number: 10688408
    Abstract: An apparatus for separating a feed stream into product streams. The apparatus includes an upper section, a middle section, and a lower section. The middle section has a dividing wall separating it into two portions. A liquid barrier blocks the flow of liquid from the upper section into the middle section and allows vapor to flow from the middle section to the upper section. A vapor and liquid barrier blocks both the flow of both vapor from the lower section to the middle section and the flow of liquid from the middle section to the lower section. Vapor conduits allow vapor to flow from the lower section to each of the middle portions in varying amounts. Also processes for separating a feed stream.

  • Patent number: 10689583
    Abstract: A process is presented for the removal of contaminants like sulfur compounds from hydrocarbons. The sulfur compounds are removed from hydrocarbons that may be a feed to cracking units. A feed stream is treated with a clinoptilolite or a barium exchanged zeolite adsorbent to effectively remove carbon disulfides from the feed hydrocarbon. The adsorbent may be regenerated by a hydrogen stream, a hydrocarbon stream or a mixture thereof.
