Superkritične tekočine

Cujnik, Marko (author), Jamnik, Andrej (mentor)

Superkritičnih tekočin ne srečujemo v vsakdanjem življenju, saj so v naravi prisotne samo v okoljih z ekstremnimi pogoji. Tako, se z njimi srečujemo le v znanosti, torej v laboratorijih, kjer take pogoje lahko zagotovimo. Superkritične tekočine se pogosto uporabljajo pri različnih proizvodnih postopkih, saj imajo posebne lastnosti, zaradi katerih se razlikujejo od običajnih tekočin in plinov.

Abstract

Supercritical fluids are not encountered in everyday life, as they are only present in nature in environments with extreme conditions. Thus, we only encounter them in science, that is in laboratories where such conditions can be assured. Supercritical fluids are widely used in various industrial processes because they have special properties that make them different from ordinary liquids and gases.

• Keywords: Supercritical fluid, phase diagram, critical point, density, solubility, viscosity, thermal conductivity, diffusion coefficient, extraction, chromatography.
