By using thermodynamic phenomena in systems with dense gases, product
properties such as morphology, size of particles, and fibers can be ta
ilored to industrial needs. Separation of complex mixtures can be perf
ormed. Processes that are conventionally operated in a number of costl
y steps can be reduced to a few operations. This paper gives a phenome
nological classification of such processes and explains the underlying
principles. Operations developed on a laboratory scale as well as tho
se already established in industry will be critically discussed and co
mpared to conventional methods. An up-to-date review of the state of d
evelopment starting from the emergence of these technologies in the ea
rly 1980s is given.
