Lecture
This lecture explores the concept of heat recovery in industrial processes, focusing on the economic balance between energy savings and investments in heat exchangers. By analyzing temperature enthalpy profiles, the instructor demonstrates how to calculate the maximum heat recovery achievable by cascading heat from hot to cold streams. Through a systematic approach, the lecture presents an algorithm for determining the minimum energy requirement and the amount of heat that can be recovered. Practical examples illustrate the application of the method, emphasizing the importance of optimizing energy usage in industrial systems.
