An Efficient Coupled Genetic Algorithm-NLP Method for Heat Exchanger Network Synthesis

An NLP Approach for Evolution of Heat Exchanger Networks Designed by Pinch Technology

Common methods to design heat exchanger networks (HENs) by pinch technology usually need an evolutionary step to reduce the number of heat transfer units. This step <span style="font-size: 10pt; color:...

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...

Isothermal Reactor Network Synthesis Using Coupled NonDominated Sorting Genetic Algorithm-II (NSGAII) with Quasi Linear Programming (LP) Method

In this study a new and robust procedure is presented to solve synthesis of isothermal reactor networks (RNs) which considers more than one objective function. This <span style="font-size: 9pt; color: #0...

Spiral heat exchanger optimization using genetic algorithm

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...
