  • Process for the simulated moving bed separation of xylenes, and optimized operating conditions
    Patent number: 10150717
    Abstract: The present invention describes a process for the simulated moving bed separation of xylenes, in which the operating conditions are optimized by means of a specific relationship between the cycle time and the flow rate of the desorbant.
    Type: Grant
    Filed: March 12, 2018
    Date of Patent: December 11, 2018
    Assignee: IFP Energies Nouvelles
    Inventors: Alexandre Vonner, Damien Leinekugel Le Cocq, Catherine Laroche, Pascal Etienne
  • SIMULATED MOVING BED XYLENES SEPARATION PROCESS, AND OPTIMIZED OPERATING CONDITIONS FOR UNITS TREATING PARAXYLENE-RICH FEEDS
    Publication number: 20180334415
    Abstract: The present invention describes a process for the simulated moving bed separation of xylenes which can be used for the treatment of paraxylene-rich feeds (more than 25% by weight of paraxylene), in which the operating conditions are optimized by means of a specific relationship between the cycle time and the desorbant flow rate.

  • NOVEL CONCEPT FOR COLLECTION AND DISTRIBUTION CHANNELS FOR A SIMULATED MOVING BED SEPARATION PROCESS USING N-COLUMNS IN SERIES
    Publication number: 20180296941
    Abstract: The present invention describes a device for supplying or collecting from a column forming part of an assembly of columns in series, for use in a simulated moving bed separation process. The present device can be used to very substantially reduce the non-selective volumes in each column.
