Elin Svensson will hold her docent lecture (for ”oavlönad docent”). Elin is employed at Chalmers industriteknik, and defended her dissertation 2012 in the research group Industrial Energy Systems and Technologies at the previous Department of Energy and Environment.
Title: Energy-efficient industrial processes: Feasibility of heat recovery projects considering operability, process layout constraints and flexibility
The integration of industrial processes through process heat recovery can significantly contribute to more efficient use of energy and resources in industry. Methods for estimating the potential for such energy-efficient heat integration are commonly based on so-called pinch methodology, which builds on thermodynamic insights and techno-economic trade-offs. A core strength of pinch methodology is that it enables setting performance targets, which can guide early-stage design activities or be used to assess the potential of new processes. However, such targets are necessarily based on theoretical assumptions, and typically do not consider constraints for heat integration that may arise due to process operability requirements, existing site layout or safety considerations. Particularly in retrofit situations (i.e. when changes are made to an existing plant), the usefulness of these targets is thus limited. In this lecture I will discuss examples of this, and present some recent research that proposes new ways to better incorporate operability and implementation issues during early-stage targeting and design of industrial heat recovery projects.
