This lecture covers the analysis of heat transfer interfaces in unit operations, focusing on pinch points and energy optimization strategies such as the Plus-Minus principle. It discusses the integration of oil-free micro-turbines, process demand interface modifications, and the concept of heat cascades. The lecture also explores examples of pressure changes in columns, multi-effect evaporators, and heat pump efficiency. Energy-saving scenarios, heat pumping principles, and absorption heat pumps are analyzed, emphasizing the importance of optimizing heat pump performance around pinch points.
