Abstract:
This paper proposes an approach for synthesizing multi-stream heat exchanger network based on the effective temperature levels of streams named "stream pseudo-temperature". Pseudo-temperature is obtained by the stream heat transfer temperature difference contribution value which is optimized with Genetic/Simulated annealing algorithm. Pinch point and utilities are presented, and a temperature-enthalpy diagram is constructed based on the stream pseudo-temperature. An automated method for multi-stream heat exchanger network synthesis using the temperature-enthalpy diagram is given. The performance of the proposed approach is demonstrated using an example and better solution is obtained compared with literatures.
