  • Publication number: 20090186153
    Abstract: A process for the “in situ” manufacture, in a pressurized CO2 medium, of coated particles. The manufacturing process is characterized in that the steps of synthesising the particles and of coating these particles are coupled in such a way that the synthesised particles remain dispersed in a pressurized CO2 medium at least until the coating. The device comprises a reactor for synthesising particles in a pressurized CO2 medium; a means of injecting the coating material or precursor thereof into said reactor; a means of supplying said reactor with a pressurized CO2 medium; in which the means of injecting the coating material or precursor thereof is coupled to the synthesis reactor in such a way that the injection of the coating material or precursor thereof into said reactor does not destroy the dispersion of the particles, in a pressurized CO2 medium, in said reactor.

  • Patent number: 5961835
    Abstract: A process and installation for the separation of heavy and light compounds is provided. According to the process, a solid or liquid phase containing the compounds to be separated is contacted with a supercritical fluid in an extractor, after which the supercritical fluid containing compounds leaving the extractor undergo nanofiltration for recovering a permeate flow containing the light compounds and a retentate flow containing the heavy compounds. The invention has particular utility for separating fats in food stuffs such as butter or fish oil.
