  • Method for inline measurement on simulated moving bed units or hybrid units for separation by simulated moving bed and crystallization, and application to the control and regulation of said units
    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
    Filed: December 7, 2017
    Date of Patent: January 29, 2019
    Assignee: IFP Energies Nouvelles
    Inventors: Javier Perez Pellitero, Catherine Laroche, Olivier Delpoux, David Goncalves
  • Dynamic suspension drying (DSD) to control Ostwald Ripening
    Patent number: 10151529
    Abstract: The present invention relates to a process for the control of Ostwald Ripening phenomenon occurring in particle suspensions without the need for addition of stabilizing agents, by using high pressure homogenization at mild conditions in a way that no increase or decrease in particle size occurs, thus allowing the stabilization of the suspension during the isolation step in the form of a dried powder.
