Goals:  The objective of this course is to introduce students to the principles of thermodynamics as they apply to chemical processes.

 

Knowledge, Abilities, and Skills Students Should Have Entering This Course:

1.      Units, material and energy balances, the use of steam tables and P-H charts (ChE 317).

2.      The first law of thermodynamics, enthalpy,  and heat capacity (ChE 317).

3.      Ideal gas and real fluid behavior (ChE 317).

4.      Solution of simple chemical engineering process problems (ChE 317).

5.      The first and second laws of thermodynamics (Ch 353).

6.      State functions and path-dependent functions in the solution of chemical problems (ChE 353).

7.      The theoretical aspects of thermodynamics and the treatment of ideal and real fluids (Ch 353).

8.      Deviations from ideality by use of various equations of state (Ch 353).

9.      Solution thermodynamics (Ch353).

 

Knowledge, Abilities, and Skills Students Should Gain Form This Course:

1.      The student should be able to apply energy and entropy balances to open and closed systems and to evaluate the thermodynamic efficiency of compressors, turbines, Rankine cycles and refrigeration cycles.  They should be comfortable using steam tables, P-H, T-S, and H-S charts and calculating residual properties with equations of state.  They should be able to derive property relationships using multivariable calculus.

2.      The student should be able to solve phase equilibria problems involving vapor, liquid and solid phases.  They should know how to use experimental data to evaluate the constants for various empirical equations, e.g. Van Laar, Margulies, and to use these equations to construct binary phase diagrams.

3.      The student should be able to set up and calculate yields from homogenous and heterogeneous reaction equilibria.

 

 

 

Impact on Subsequent Courses in Curriculum:

Thermodynamic properties, phase equilibrium and chemical reaction equilibrium play an important role throughout chemical engineering, e.g. in ChE 360, ChE 363, ChE 372 and ChE 473K.  Thermodynamics is one of the main pillars of chemical engineering; others include transport phenomena and reaction kinetics.

Make-up Exams

Contact the instructor or one of the secretaries immediately if you have a legitimate reason to take a make-up exam.  No make-up for homework unless agreed to before they are due.  Your are expected to miss no more than 2-3 classes, if any, for the whole semester.
