Course objectives

The aim of the course is that students acquire knowledge in applying the basic laws of thermodynamics and advanced mathematical methods to solutions of chemical engineering problems.

Course enrolment requirements and entry competences required for the course


Learning outcomes expected at the level of the course (4 to 10 learning outcomes)

After passing the exam, students are expected to:
- evaluate the thermodynamic properties of the pure substances, mixtures and solutions based on the pressure, temperature and composition
- select the required literature thermodynamic data and theoretical relationships to describe the dependence of various thermodynamic properties of real gases, mixtures and solutions on pressure and temperature
- apply different types of phase diagrams, tables and numerical expressions to display thermodynamic properties of real gases and solutions
- calculate the thermodynamic properties of real fluids using the equations of state
- calculate the thermodynamic properties of real solutions using a model of the activity coefficient
- apply the acquired knowledge of thermodynamic and advanced mathematical methods to solve chemical engineering tasks

Exam (II preliminary exam)
Numeric examples demonstrating the topics covered are analysed during the course and make an integral part with lectures.
During exercises, examples from engineering practice are solved using PC and available software.
Laboratory exercises:
1. Thermal storage of solar energy
2. Partial molar quantities
3. Vapour-liquid equilibrium

Grading and evaluating student work in class and at the final exam

Continuous assessment through partial preliminary exams (twice in a semester) allows for exemption from the written exam. The passing threshold is 60%. Partial preliminary exams are not mandatory. Preliminary exams are not eliminatory.
Each passed preliminary exam participates with 18% in the rating. Attendance to lectures and seminars for 80%-100% is 5% of the grade. Activity in lab excercises is 5% of the grade. The oral exam participates with 54 %.
A written and an oral exam are held in the examination periods. The oral exam is mandatory for all students, and the written exam is mandatory if a student is not exempt from it. A passed preliminary exam also participates with 10% in the summer examination period. The written exam participates with 36%, and the oral one with 54%. Students who have not passed the written exam through preliminary exams take the full exam (final exam) consisting of the written and the oral exam in regular examination periods. The passing threshold is 60%. The written exam form participates in the rating with 46% and oral one with 54%..
Ratings: 60%-70% - satisfactory, 71%-80% - good, 81%-90% - very good,
91%-100% - excellent.

Quality assurance methods that ensure the acquisition of exit competences

Quality assurance will be performed at three levels:
(1) University Level;
(2) Faculty Level by Quality Control Committee;
(3) Lecturer’s Level.
