Course detail

Balancing of Process and Energy Systems

FSI-KBPAcad. year: 2018/2019

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 analytical and numerical 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.

Learning outcomes of the course unit

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.

Prerequisites

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

Co-requisites

None

Planned learning activities and teaching methods

The course is taught through lectures introducing the basic principles and theory, explaining of solution methods and showing solution methods. Lectures include sample problems that are solved interactively with the students, with emphasis on understanding. Lectures include repetition of the most important prerequisites that are necessary to master the subject.

Seminars are focused on hands-on solution of sample problems with examples of work in software tools.

Assesment methods and criteria linked to learning outcomes

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).

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.

Specification of controlled education, way of implementation and compensation for absences

The attendance at seminars is obligatory, 3 absences are allowed. Participation at the lectures is not checked, but completion of assignments in the seminars requires knowledge from the lectures.

Recommended optional programme components

Enhancement of the knowledge of English, mainly the ability to understand written text.
