CH5050 – Advanced Chemical Engg Thermodynamics

CH5050 – Advanced Chemical Engg Thermodynamics


  • This core course in advance chemical engineering thermodynamics aims to connect the concepts, and laws of classical thermodynamics to applications that require quantitative knowledge of thermodynamic properties at macroscopic level.
  • The purpose of this course is to present a broad understanding of the thermodynamics of phase equilibria typically encountered in design of chemical processes, in particular, in separation operations.
  • Phase and chemical equilibria of multi-component systems are covered. While on one hand molecular thermodynamics are discussed to understand the multi-component interactions; practical cases and industrial applications are emphasized through interactive tutorial session.

Learning Outcome:

  • At the end of the course, students will be able to formulate solutions to phase equilibrium problems for complex systems based on classical and molecular thermodynamics
  • Students will be able to relate thermodynamic concepts to applications in the separations, particularly related to petroleum and chemical process industries

Course Content:
