• Abstract: Energy integration in industrial processes is a key strategy to reduce utility consumption and promote sustainability. This review paper provides a comprehensive overview of heat exchanger network (HEN) synthesis, the application of the Organic Rankine Cycle (ORC) for low-temperature waste heat recovery, and the role of metaheuristic methods in energy optimization. Sequential and simultaneous approaches for HEN synthesis are discussed, along with Pinch Analysis and different ORC configurations (basic, regenerative, and with turbine bleeding). Furthermore, the relevance of algorithms such as Particle Swarm Optimization is emphasized for solving complex optimization problems. The review highlights the potential of integrating these technologies to enhance energy efficiency, reduce costs, and minimize environmental impacts, while also identifying challenges and future research directions.
