  • Processes for removing entrained ionic liquid from a hydrocarbon phase
    Patent number: 9914679
    Abstract: One or more processes for recovering entrained ionic liquid from a hydrocarbon phase containing droplets of ionic liquid are described. The processes includes contacting the hydrocarbon phase containing the droplets of ionic liquid with a retaining material in a separation zone. The droplets of ionic liquid are retained by the retaining material. The ionic liquid may be recovered from the retaining material with a solvent or desorbent. The retaining material may be regenerated and the ionic liquid may be reactivated. The retaining material may be used in a wash vessel to retain or remove contaminant solids within the reactor or other vessels.
    Type: Grant
    Filed: December 12, 2014
    Date of Patent: March 13, 2018
    Assignee: UOP LLC

  • ACTIVE IONIC LIQUID MIXTURES FOR OXIDIZING ALKYLAROMATIC COMPOUNDS
    Publication number: 20150094486
    Abstract: Ionic liquid compositions derived from imidazolium based ionic liquids that have been thermally treated or thermally and oxidatively treated are disclosed. These compositions can be utilized as the medium for oxidation of alkylaromatic compounds and their oxidized derivatives or as a medium for purification of aromatic carboxylic acids.
