This text investigates the fundamental principles and mathematical models governing the equilibrium between liquid and vapor phases in multi-component chemical systems. The authors, Eduard Hála, Jiří Pick, and Vojtěch Fried, utilize their expertise in physical chemistry to provide a rigorous framework for calculating phase behavior. The book synthesizes experimental data and thermodynamic theory to assist engineers and researchers in predicting the behavior of mixtures under varying pressure and temperature conditions.

Experts recognize this work as a foundational reference for chemical engineering thermodynamics, particularly for its detailed treatment of experimental methodologies. Readers frequently note the high level of mathematical density, which requires a strong background in physical chemistry to fully utilize the provided models.
