Heat Transfer Interfaces: Pinch Point Analysis

This lecture covers the analysis of heat transfer interfaces in unit operations, focusing on pinch points and energy optimization strategies. Topics include the Plus-Minus principle for changing temperature profiles, process demand interface modifications, and the integration of heat pumps. The instructor discusses the impact of pressure changes on heat exchangers, multi-effect evaporators, and the efficiency of heat pumps. Energy-saving scenarios and the correct integration of partial flows are also explored, along with the application of absorption heat pumps and the Tri-thermal cycle. Conclusions emphasize the importance of optimizing heat pump placement around pinch points to enhance energy efficiency.
