The purpose of this study is to design a knowledge base containing information relevant to the detection of increased energy efficiency in industrial processes. This information must be stored and made accessible to those involved in energy efficiency in industry.
What information is relevant is detected by going through the imaginary phases of an energy audit and to determine for each phase which information is needed, resulting in the following categories.
1. Energy use and production volumes of sectors;
2. Existing processes, divided into sub-processes, with the specific energy use, energy and exergybalances and exergy efficiency of sub processes;
3. Newly designed processes, divided into sub-processes, with the specific energy use, energy and exergy balances and exergy efficiency of sub processes;
4. Technology Descriptions.
Finally, as an example, the developed system is applied to the following processes: milk powder production, ammonia production and asphalt production.
