Program

1. Solution Thermodynamics: fundamental concepts and relations; molar partial properties; Gibbs-Duhem equation; excess properties; chemical potential; ideal gas and Gibbs’ theorem; ideal liquid.
2. Phase Equilibrium: chemical potential and phase equilibrium; fugacity and fugacity coefficient – calculations based on the virial equation and generalized correlations; Raoult’s and Henry’s laws; Lewis-Randall rule; models for excess Gibbs energy and activity coefficients.
3. Application of Phase Equilibrium: vapor-liquid, liquid-liquid, and solid-liquid equilibria; calculation of bubble and dew points (temperatures and pressures); equilibrium compositions in non-ideal systems; flash units.
4. Equilibrium with Chemical Reaction: equilibrium constants and equilibrium conversions in homogeneous and heterogeneous systems.
5. Prediction of Properties: methodologies for the calculation of physicochemical properties.

Teaching methods and learning activities

This course includes theoretical (T) and theoretical-practical (TP) classes. In the T classes, fundamental concepts are presented and, whenever possible, illustrated with specific case studies. The TP classes are dedicated to solving practical problems, promoting active student participation. Throughout the semester, group-based continuous assessment exercises are carried out to consolidate knowledge, encourage collaborative learning, and develop student autonomy.

Calculation formula of final grade

Continuous assessment consists of 5 Practical Exercises (EP) + Final Exam (EX).

Practical Exercises (EP)

• Partial assessment of the content covered;
• Carried out in groups of 2 students;
• Maximum duration: 45 min each;
• Weight: 6% each.

Final Exam

• Global assessment covering all content;
• Maximum duration: 120 min;
• Weight: 70%.

Notes:

- Absences from Practical Exercises:

• Justifiedn in accordance with the FEUP regulations or in the case of student workers – the corresponding EP percentage is transferred to the Final Exam.
• Unjustified – score of 0.

- Final Exam is mandatory to pass the continuous assessment.

- To pass, students must obtain a grade higher than 6.5 in the Final Exam and a final grade (CF) higher than 9.5 in the course.

 

Final Grade (CF) = 0.06*EP1+0.06*EP2+0.06*EP3+0.06*EP4+0.06*EP5 + 0.70 EX
