Simultaneous Process and Heat Exchanger Network Synthesis Using a Discrete Temperature Grid

Simultaneous Synthesis of a Biogas Process and Heat Exchanger Network for a Large-scale Meat Company

The aim of this contribution is to present an industrial application of mathematical programming for the simultaneous synthesis of a biogas plant and its heat exchanger network (HEN), within an existing meat company. The heat-integrated model recently developed by Drobež et al. (2010) has been extended with Yee & Grossmann simultaneous optimization MINLP model (1990) for the synthesis of heat e...

Optimising heat exchanger network synthesis using convexity properties of the logarithmic mean temperature difference

Mathematical methods for heat exchanger network synthesis

This paper gives an overview of the evolution of mathematical methods for heat exchanger network synthesis over the last 25 years. Two major developments have been methods for targeting and methods for automated synthesis through simultaneous optimization. The former have helped to expand the scope and increase the accuracy of pinch based methods; the latter have provided a framework to automat...

Optimal Heat Exchanger Network Synthesis Including Heat Transfer Equipment Design

This paper presents an optimisation model for the synthesis of heat exchanger networks (HEN) including the detailed design of the equipments formulated as a decomposition method. Shell and tube pressure drops and fouling are considered, as well as mechanical aspects, like shell and tube bundle diameters, internal and external diameter of tubes, number of tubes, number of baffles, number of shel...

Optimal 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...
