  • Process to produce nanoparticles
    Patent number: 11298668
    Abstract: A process for producing nanoparticles of a substance, including in a first chamber, forming a dispersion of a substance in a fluid and bringing the fluid into a supercritical state; passing the dispersion from the first chamber through a cooling device or into a cooling zone in a second chamber, wherein the cooling device or cooling zone configured to reduce temperature of the dispersion below a temperature at which the fluid forms solid particles such that nanoparticles of the substance are formed, wherein the second chamber comprises a surface configured to receive the solid particles of the fluid and the nanoparticles of the substance; allowing pressure to decrease and/or temperature to increase in the second chamber to transform the solid particles into a gaseous state, removing the fluid in the gaseous state and with the nanoparticles remaining on the surface; and collecting the nanoparticles from the surface.
    Type: Grant
