Vapor-Liquid Equilibrium and Distillation for GATE Chemical Engineering

Succeeding in the mass transfer section of the GATE Chemical Engineering exam requires a rock-solid grasp of vapor-liquid equilibrium (VLE) and distillation principles. This course guides you from foundational thermodynamic concepts to solving complex distillation problems, equipping you with the analytical skills needed to tackle exam-style questions. What you'll learn: - Understand the thermodynamic principles of vapor-liquid equilibrium, including Raoult's Law and non-ideal system behaviors. - Analyze simple, flash, and steam distillation processes using material and energy balances. - Apply the McCabe-Thiele method to determine the number of theoretical stages in continuous distillation columns. - Evaluate key column parameters such as reflux ratio, feed plate location, and minimum reflux. - Practice solving representative exam-style questions with step-by-step written explanations. - Explore modern thermodynamic models like NRTL and UNIQUAC used to predict VLE in industrial processes. The course begins with essential VLE terminology and phase diagrams, progressing through different distillation techniques, and concluding with detailed walkthroughs of classic exam problems. Designed for chemical engineering students and graduates preparing for competitive exams, with no advanced mass transfer prerequisites required.
