| Learning Outcomes of the Course Unit |
|---|
The objective of the course: to explain the basic principles of mass and energy balancing in the description of technological processes. Demonstrate practical procedures for balancing of complex systems using automated calculations.
Acquired knowledge: stoichiometric calculations, material balances of single-stage processes (mixer, splitter, separator, crystallizer) and multistage processes (solution preparation + concentration adjustment, recycle, by-pass).
Acquired skills: using and converting values in units based on the SI system, expressing the composition of compounds and mixtures in different ways and recalculating them, stoichiometric calculations (calculating the mass of reactants/products, the composition of the reaction mixture) including applying conversion, yield or losses. Fundamentals of the energy balances in simple processes. |
