Heat exchanger network synthesis with multiple utilities using a generalized stagewise superstructure with cross flows

چکیده
Most of the existing simultaneous approaches for heat exchanger network synthesis assume that only one type of hot/cold utility is available to adjust the final temperatures. In this work, we propose a simultaneous mixed-integer nonlinear programming formulation based on a more generalized stagewise superstructure. We allow utilities to adjust the temperature of process streams in each stage. We also focus on including the certain that the previous stagewise superstructure and hyperstructure neglects. Using several examples, we demonstrate the significant advantages of our approach compared to those from the literature.

Synthesis of non-isothermal water networks including process hot and cold streams
The synthesis problems of non‒isothermal water networks have received considerable attention throughout academia and industry over the last two decades because of the importance of simultaneously minimising water and energy consumption [1]. Most papers have addressed this issue only by considering heat integration between hot and cold water streams. In this study, the scope of heat integration ...
متن کاملOptimal synthesis of heat exchanger networks involving isothermal process streams
This paper proposes a new MINLP model for heat exchanger network synthesis that includes streams with phase change. The model considers every possible combination of process streams that may arise within a chemical process: streams with sensible heat, streams with latent heat, and streams with both latent and sensible heat. As part of the optimization strategy, the superstructure is modeled wit...
