  • Precipitation of solids with dense gas
    Knez, Željko
    The particle-size and size-distribution of solid materials produced in industrial processes are not usually those desired for subsequent use of these materials and, as a result comminution and ... recrystallization operations are carried out. Well known processes for particle size redistribution are crushing and grinding (which for some compounds are carried out at cryogenic temperatures), air micronization, sublimation and recrystallization from solution. There are several practical problems associated with the above mentioned processes. Some substances are unstable under conventional milling conditions, and in recrystallization processes the product is contaminated with solvent, and waste streams are produced. Applying supercritical fluids may overcome the drawbacks of conventional processes.
