Energy in process engineering

• Procesna tehnika i zaštita životne sredine, Semester 2, position 5
• Hidroenergetika, Semester 2, position 5

Mastering the basic knowledge and skills of using the energy in process industry in order to adequately deal with the practical matters of rational use of energy and maintenance of energy equipment and systems in industrial companies. In addition, basic knowledge of the transformation and energy use are essential for the understanding of matter from other subjects of process engineering and environmental protection.

Understanding the operation of energy equipment and technologies and principles of their rational use. Preparation of the energy balance of industrial companies; implementation of energy auditing procedure, energy data collection and implementation of methodology for defining the energy losses of equipment and installations in industrial plants.Understanding basic terms within Energy Management System (ISO 50001:2011). Basic concept of BAT (Best Available Techniques) in energy efficiency in industrial plants.

1. Energy, energy transformation and utilization of energy in production processes in industry (general concepts on energy sources and energy reserves; an overview of energy consumption and energy systems in industrial plants, energy balances of industrial companies). 2. Energy sources in industrial companies (power supply of industrial plants, boilers and boiler rooms, the combined heat and power production in industry, energy requirements for production processes). 3. Utilization of fuels in industry (distribution of fuels, combustion systems, combustion and basics of combustion efficiency). 4. Steam as energy carrier (steam characteristics, processes and equipment that uses steam in the process industry; characteristics of distribution systems for steam and condensate return). 5. Compressed air (systems for compressed air supply in industrial companies, distribution of compressed air, quality and preparation of compressed air, energy efficiency improvements in compressed air system). 6. Energy efficiency in lighting systems in industrial companies. 7. Financial analysis of energy efficiency measures for energy utilities in industrial companies.

1. Preparation of energy balance (methodology of collecting data on energy consumption in industrial companies; examples of energy balance of selected companies). 2. Review of energy systems in process engineering and calculation of coefficient of efficiency (power supply of industrial plants; boilers and boiler rooms, the combined heat and power production in industry, energy requirements of production processes). 3. Calculation of energy losses in distribution systems for steam and condensate return (steam quantity used for the production process; calculation of energy losses through the pipeline walls; calculations of energy losses in case of improper drainage of condensate). 4. Calculations of energy losses in industrial equipment that use the fuel (e.g. calculation of the combustion process, calculation of flue gas waste heat). 5. Calculation of energy losses of compressed air system. 6. Possible energy savings within lighting system. 7. Financial analysis of proposed energy efficiency measures in energy utilities in industrial companies. 8. Preparation of the seminar work - Energy Audit in selected industrial company (students doing their paper work and calculations, with the help of teaching assistant; they are obliged to prepare written report on energy audit within one selected industrial company as well as power point presentation). Seminar work will be done in teams.
