In this paper different waste heat recovery systems are investigated for Cytiva’s solvent recyclingfacility. Currently steam is used to distill ethanol before cooling it with condenser fans. Thecooling demand varies severely, and peak demand need to be handled with smart energy storagesolutions such as hot water storage tanks or salt storage. Potential heat sinks for the waste heat arelocal heating, heating water for internal use, steam condense and electrical energy generation.Python is used to simulate results with data from Cytiva. The suggested systems are evaluatedbased on yearly performance, savings and environmental impact. A comparison between thedifferent potential systems concludes that none of the investigated solutions can handle the entirecooling demand by itself and redundancy is missing during the summer months. Whenimplemented, the final solution should be a combination of multiple systems.
