Thermodynamics of Fluid Phase Equilibria: A Practical Guide

Predicting how mixtures of fluids behave under different temperatures and pressures is essential for designing efficient chemical separation processes. This text-based course breaks down the complex mathematical and physical principles of phase equilibria into clear, accessible concepts. You will transition from understanding basic thermodynamic laws to confidently calculating vapor-liquid, liquid-liquid, and solid-fluid equilibria. By working through written explanations and practical calculation scenarios, you will build the skills needed to solve real-world chemical engineering problems. What you'll learn: - Understand the fundamental principles of chemical potential, fugacity, and phase rule criteria. - Calculate vapor-liquid equilibria (VLE) using both ideal laws and advanced equations of state. - Apply activity coefficient models to describe non-ideal liquid mixtures. - Analyze multi-component phase envelopes and high-pressure phase behavior. - Explore modern thermodynamic frameworks and association models used in industrial process design. - Practice phase stability analyses through step-by-step written exercises. The course starts with essential thermodynamic definitions and the criteria for phase equilibrium before progressing to equations of state and non-ideal mixture models. You will then study multi-component systems and modern computational approaches to phase behavior. This course is designed for chemistry students, chemical engineering undergraduates, and professionals seeking a solid refresher in thermodynamic modeling. No advanced prior knowledge of phase equilibria is required, as we begin with foundational concepts.
