Around half of the energy consumed in aluminum production is lost as waste heat, with approximately 30-45% of this heat carried away by the exhaust gas from the smelter. This study focuses on modeling low-temperature energy utilization in aluminum production using scenarios such as an organic Rankine cycle (ORC) system for electric power generation, heat supply system, and combined heat and power (CHP) system. The potential for electric power generation was assessed, finding a maximum output of 2.57 MW with R-123 as the working fluid at an evaporation temperature of 61.22°C. The heat supply system could produce 42.34 MW, sufficient for local district heating needs, with additional opportunities for agriculture and industrial applications. The CHP system produced 1.156 MW of power alongside a heating capacity of 23.55 MW. The research highlights the heat supply system's efficiency compared to the ORC, indicating significant potential for recovering waste heat from aluminum production processes. Enhancing ORC efficiency shows promise for further optimizing energy utilization in this industry.
