The course deals first with thermodynamics of multicomponent mixtures and subsequently in detail with equilibria involving fluid phases, i.e. vapor-liquid equlibrium, solubility of gases in liquids, liquid-liquid equilibrium, and solid-liquid equilibrium. Students learn the related phenomenology, experimental techniques, thermodynamic modeling, and estimation procedures.
Aim of the course -
Last update: Dohnal Vladimír doc. Ing. CSc. (14.09.2015)

Students will be able to:

assess the effects of temperature, pressure, and composition on phase equilibria in fluid mixtures

perform engineering calculations of phase equilibria in real multicomponent systems of fluids

treat experimental data on phase equilibria using thermodynamic models

Combination of lectures, seminars and tutorials (according to personal plan). By prior agreement the study plan is flexible; the necessary condition for passing the course is the successful elaboration of a individual calculational project and related interview.
