Course detail

Balancing of Process and Energy Systems

FSI-KBPAcad. year: 2024/2025

The subject introduces to students the issue of balancing in process and energy systems. Students will learn to apply balance equation of the mass and energy conservation laws to a wide array of processes:
• Steady state processes
• Single component and multicomponent processes
• Processes with chemical reactions
• Transient processes
To solve the balances, the subject will provide compotational approaches and methods and student will practice on a number of practical examples. Emphasis will be put on the computer implementation of procedures in a widely available software MS Excel. The hot topics as energy security and energy production from renewable sources are addressed in the lectures.

Institute of Process Engineering (ÚPI)

Entry knowledge

Required is the knowledge of mathematics, physics and thermomechanics from the bachelor’s degree.

Rules for evaluation and completion of the course

SEMINARS: Regular and active attendance is required and checked, delivering all assignments is obligatory and written tests must be passed successfully. The criterion of successful completion of the seminar is obtaining more than half points in tests.

EXAM: The exam is written. Maximum overall number of points that can be obtained within the course is 100. The course evaluation is performed by a standard procedure, according to the number of obtained points (0-50 points …F, 51-60 points …E, 61-70 points …D, 71-80 points …C, 81-90 points …B, more than 90 points …A).

The attendance at seminars is obligatory, 2 absences are allowed. Apology for absence is required. Participation at the lectures is not checked, but completion of assignments in the seminars requires knowledge from the lectures.

Aims

The aim of the course is to prepare students for effective use of balancing as a basic tool of process engineer. The subject will at the same time highlight the interdependence of knowledge in other selected courses.
Students will learn that balancing is a general method of working with the conservations laws of mass, energy or species. They will acquire a systematic analytical approach towards balanced process diagram. They will learn, how to apply balancing to a mathematical description of various types of processes. The students will also learn to solve balance equations in the studied types of processes.
