  • Publication number: 20200316558
    Abstract: The present invention relates to zeolite adsorbents based on agglomerated crystals of zeolite X comprising barium, potassium, sodium and strontium. These adsorbents have applications in the separation of fractions of aromatic C8 isomers and in particular xylenes.
    Type: Application

    Publication date: October 8, 2020
    Applicants: Arkema France, IFP Energies Nouvelles
    Inventors: Catherine Laroche, Ludivine Bouvier, Javier Perez-Pellitero, Marie-Laurence Labede
  • Publication number: 20200223770
    Abstract: Provided is a hybrid process for producing high-purity para-xylene from a feedstock of aromatic hydrocarbon isomer fractions having 8 carbon atoms, in a liquid phase. The process includes a liquid chromatography separation step and a crystallization step of the para-xylene from the purified stream of para-xylene obtained at the separation step.

  • Patent number: 10190987
    Abstract: A method for measuring the concentrations of species present at at least one point of a separation unit operating in simulated moving bed (SMB) mode, or a hybrid separation unit employing a step for simulated moving bed (SMB) separation and a step for crystallization, by calibration by inline acquisition of Raman spectra for different mixtures; analysis by inline signal processing of the Raman spectrum.
    Type: Grant
