Selection of The Optimal Working Fluid in an Organic Rankine Cycle for Waste Heat Recovery Through Multi-Objective Optimization and Decision Making

In India, utilising low-temperature waste heat is crucial to improving energy efficiency. The regenerative organic Rankine cycle (ORC) process is a promising waste heat recovery technique in this study. Here, the thermodynamic behaviour of eight working fluids: Butane, Heptane, Hexane, Pentane, Cyclopentane, HexMDiSiloxn (MM), Benzene, and Toluene, was carefully examined. An elite Nondominated sorting genetic sorting algorithm (NSGA-II) was used in Multi-objective
