Method and apparatus for the precipitation and coating particles using antisolvent quasi-critical and supercritical.

摘要

METHOD AND APPARATUS (110) Perfected FOR PRECIPITATION AND PARTICLE COATING FLUIDS USING STATES OR NEAR CRITICAL Supercritical. A dispersion (128) FLUID having a continuous dispersing phase and a substance PRECIPITABLE LEAST contact an antisolvent (126) supercritical fluid (SCF) to generate Sonics antisolvent HIGH FREQUENCY, Decomposing DISPERSION IN DROPS VERY SMALL. INCREASED THE MASS TRANSFER BETWEEN AMOUNTS drops and anti-solvent causes precipitation of very small particles ORDER OF 0.1-10 microns. COATING PROCESSES ARE TURBULENT FLUID FLOW CREA PARTICLE USING NUCLEAR SCF antisolvent in an enclosed area. DISPERSION the fluid containing a dispersant and a substance PRECIPITABLE allows particles NUCLEAR ARE IN MUTUAL CONTACT ZONE IN THE UNITED CASI BLISS critical or supercritical. Antisolvent REDUCES THE SUBSTANCE DISPERSANTEY rushes over fluidized particles.
