Subject Descriptions (VNT) - Summer Semester
Heat transfer
Basic knowledge of the transport laws for thermal energy (conduction, convection, radiation) is acquired.
Contents of the lecture are first the basics for the phenomenological description of the mechanisms conduction, convection and radiation and based on this their application to stationary and transient problems of heat conduction, heat transfer at fins, heat transfer of multilayered bodies (plate, cylinder, sphere), the calculation of heat exchangers and the optimization of heat transfer processes.
Fundamentals of Process Engineering and Natural Materials Engineering
The course is designed to introduce the student to the typical ways of thinking and working in thermal process engineering. Knowledge and skills are imparted on material and energy balances, on the modeling of selected heat and mass transfer processes and on the state description of humid air, as they are used as a basis for the design of simple apparatus. Differential consideration of micro processes and integral description of process units complement each other. The focus of the presentation is on process models. They are extended by models and principle descriptions of simple apparatus and plants.
Deepening and application of thermal process engineering
Contents of the module are advanced basic processes of thermal process engineering such as rectification, the determination of the number of stages of rectification columns in the enthalpy composition diagram (Ponchon-Savarit method), the calculation of packed columns using the two-film theory and the HTU-NTU concept, chemical absorption (equilibrium, kinetics), the fluid dynamic design of packed and packed columns as well as evaporation and crystallization processes. Further contents of the module are processes of exhaust air purification (thermal and catalytic afterburning, biological oxidation, condensation, adsorption as well as absorption) and their specific properties and fields of application as well as the purification of flue gases (state of the art in power plants, residue treatment and regenerative processes) and the processes of wastewater treatment in municipal wastewater treatment plants.
Energy Process Engineering - Part: Energetic Process Integration
The students have knowledge about methods of heat integration as well as their apparative implementation. The thermodynamic fundamentals, the systematic planning procedure and the economic evaluation or optimization of the energetic process integration are in the foreground. The students are able to calculate temperature profiles in single and multi-component systems with and without phase transformation and, on this basis, to minimize exergy losses using the pinch-point method. Students will be able to network mass transfer and heat transfer equipment to achieve an integrally optimal equipment and system configuration.
Environmental process engineering - Part: Waste disposal technology
The students have knowledge about technical measures and procedures of the aftercare environmental protection, possibilities to apply these purposefully and to implement and supervise methods of the environmental management. The students are able to identify thematically main features of the aftercare environmental protection on the basis of the analysis of case studies and examples from different branches of industry and to deal critically with strategic approaches and principle solution variants. Emphasis is placed on technologies for sustainable development as well as process optimization, choice of input materials, product design, life cycle assessment.
