Course detail
Technological Units for Processing Industry
FSI-KS2 Acad. year: 2024/2025 Summer semester
The course of “Technological Units for Process Industry” extends the knowledge from previous partial subjects of the specialization, especially thermodynamics engineering. The course is divided into two main parts. The first part extends the students’ knowledge of thermodynamic regularities for equilibrium in systems where chemical reactions take place. In the first part kinetic factors influencing the behaviour of processes in different types of reactors will be analysed. The approach to balancing of unsteady technological systems includes also the mass and heat accumulation. The approach to design of reaction knot of sample technologies using kinetic model of alternative reactor types will be shown. In the second part of the course, systematic survey of the most important industrial technologies (industry of complex crude-oil treatment and natural gas processing, chemical and petrochemical industry, cement and lime industry) and especially technology for thermal treatment of communal and industrial wastes will be presented among others.

Entry knowledge
Basic knowledge of thermomechanics and thermodynamics, especially computation of thermal effects of chemical and physical processes. Knowledge of hydraulic process and thermodynamic Engineering.
Rules for evaluation and completion of the course
To gain the credit, a semestral paper has to be submitted. The topic of the paper is given during the semester and the main tasks of the paper are continually discussed during exercises. The credit is also granted upon regular attendance on exercises and the students’ performance during exercises that prove that they have gained basic knowledge of the course during the semester.
The results of semester papers are presented in the form of short presentations prepared by students.
The exam consists of a written and an oral part. In the written part, the student has to prove the ability to solve individually three given computation tasks. During the oral exam, the student will explain the solution of the computation and prove knowledge of the lectures’ topics. The overall evaluation also considers the level of the semestral paper.
During the course there are 13 lectures (2 hours) and 13 exercises (2 hours). The supporting text of lectures is available in digital form. The attendance at lectures is recommended. The exercises are carried on in given classroom and follow the topics of the lectures. The attendance at seminars is mandatory and monitored.
Aims
The course objective is to familiarize the students with the most important process plants, methodology of process plant creation, its balancing and complex evaluation of its suitability for given intention. Students will be able to apply the knowledge of physical and chemical regularities to the conceptual design of a manufacturing line and make a qualified decision between more possible solutions.
The important process plants are connected with series of examples and calculation solutions of concrete industrial applications. It enables to demonstrate the issues of plants creation and complex evaluation of plants conception and possibilities, together with evaluation of individual equipment and its influence on the plant’s characteristics.
Students will be able to apply their knowledge of regularities for conceptual design of technological process and make qualified decisions between more possible solutions.
