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 the student is expected to know:
- explain the law of conservation of mass and write general material balance equation on (continuous) steady-state and (batch) unsteady-state processes,
- write material balances on unreactive and reactive processes,
- write a flowchart of single and multiple-unit processes and solve the system of mass balance equations in order to define amount and composition of material of each process stream,
- apply the law of conservation of energy and write energy balances for chemical processes,
- write energy balances on opened and closed steady-states systems,
- apply simultaneous material and energy balances.
