Course Description

The course focuses on the following topics:

• Material balances (atomic and molecular balances) for individual units and an overall process
• Material balance and stoichiometric calculations of reactor systems
• Degree of freedom analysis to determine if a problem is solvable
• Process approaches for solving energy balance problems
• Energy balance in single-phase systems with and without reactions

• Process calculations with Aspen Hysys
• Energy balance of combustion processes, computation of adiabatic flame temperature
• Energy resources and energy consumption nationally and globally
• Alternative energy systems, with a focus on wind and bioenergy

Teaching and Learning Methods

Lectures and exercises. Presence at all Aspen Hysys simulation lab exercises is obligatory.

Assessment Methods

The assessment will determine whether the candidate has achieved the learning outcomes in terms of knowledge and skills.

Written individual mid-term examination (30%).

Written individual final examination (70%), which must receive a passing grade in order for the student to receive a passing grade for the course.

Minor adjustments may occur during the academic year, subject to the decision of the Dean
