This paper presents the optimization of ORCs for recovering waste heat from a hypothetical aluminum production plant to be installed in Norway. The case study is particularly interesting because it features two hot streams at different temperatures (the pot exhaust gases and the cell wall cooling air) which make available about 16 MWth below 250 °C. First, a recently proposed cycle optimization approach is adopted to identify the most promising working fluid and optimize the cycle variables…

Organic Rankine Cycle for Waste Heat Recovery in a Refinery
Waste heat recovery is one of the most important development fields for the organic Rankine cycle (ORC), where a low boiling point organic fluid is used as a working medium. The ORC can be applied to
Waste Heat Recovery from Aluminum Production
Around half of the energy consumed in aluminum production is lost as waste heat. Approximately 30–45% of the total waste heat is carried away by the exhaust gas from the smelter and is the most
