“…Several papers and reviews dealing with hydrodynamic modeling of the RESS process, phase behavior of expanding mixtures, and particle formation mechanisms have been published in the past decade (5,25,51,(65)(66)(67)(68). It is generally possible to model the formation of particles with the RESS process by simultaneously resolving the mass, momentum, and energy balances in combination with the proper EoS and general dynamic equation.…”

“…Jet breakup time and dynamic surface tension vanishing have been considered as mechanisms in competition during supercritical antisolvent precipitation, and a mathematical model, based on these two characteristic phenomena, was presented in the work of Marra et al (128). Numerous applications of antisolvent processes for different substances have also been published (5,24,65,66,88,(129)(130)(131)(132). Aside from papers published through November 2012 (5), several recent new applications for different substances have been published, as presented in Table 3.…”

Traditional methods for solids processing involve either high temperatures, necessary for melting or viscosity reduction, or hazardous organic solvents. Owing to the negative impact of the solvents on the environment, especially on living organisms, intensive research has focused on new, sustainable methods for the processing of these substances. Applying supercritical fluids for particle formation may produce powders and composites with special characteristics. Several processes for formation and design of solid particles using dense gases have been studied intensively. The unique thermodynamic and fluid-dynamic properties of supercritical fluids can be used also for impregnation of solid particles or for the formation of solid powderous emulsions and particle coating, e.g., for formation of solids with unique properties for use in different applications. We give an overview of the application of sub- and supercritical fluids as green processing media for particle formation processes and present recent advances and trends in development.
