This course designed for PhD students focuses on practical applications of chemical thermodynamics for solution phase equilibria problems. The PhD candidate resolves three complex jobs. For each job there will be an introductory lecture which provides the candidate with the necessary theoretical basis and an appropriate solution methodology. Each task will involve identifying, retrieving or estimating the necessary input data and their critical evaluation, performing numerical calculations, estimating the uncertainty of the results and their discussion, as well as the job documentation. The PhD students are expected to work with universal program resources (MAPLE, Excel, Mathematica, etc.), existing databases (Knovel, DIPPR, REAXYS) and specialized application programs (e.g. UNIFAC). How to troubleshoot a student can consult and the results achieved must defend. While the PhD students are encouraged to consult their proceedings, they are obliged to defend results obtained.

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

Teaching methods -
Last update: Řehák Karel doc. Ing. CSc. (27.05.2019)

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 individual calculational projects and related interview.
