There is a great potential for saving energy in the process industry through heat recovery. But, although the theoretical opportunities are great, the full potential can rarely be reached due to practical, technical barriers. In this project the extent of, and causes for, the difference between the theoretical saving potential and what can be achieved in practice is analyzed.
The project is a collaboration between Chalmers, Preem and CIT Industrial Energy. The analysis is, to a great extent, based on interviews with persons who have a great experience and knowledge about the processes in an oil refinery. The results of the interviews are then used to analyze the technical barriers to heat integration, but also to identify possible driving forces to implement larger energy efficiency projects.
To optimize energy use in industrial plants is a necessity for lowering carbon dioxide emissions and for efficient integration of new processes based on, e.g., new technology and renewable feedstock in the existing plants. The project is anticipated to contribute to more general conclusions about what is required to reach greater energy savings in industry.
