Much work on heat exchanger network synthesis (HENS) via mathematical programming
has employed a stagewise superstructure with the assumption of isothermal mixing. It is well …

A heuristic approach to improving current automatic heat exchanger network synthesis
(HENS) methods is presented, where the various sets of matches that all achieve the …

Abstract Heat Exchanger Networks (HEN) synthesis is a process engineering problem that
can be mathematically characterized as highly combinatory, non-linear and non-convex. All …

The synthesis of heat exchanger networks (HENs) is a complex problem because of the
nonlinearity that results from the integer and continuous variables. Here, a bi-level algorithm …

In this work, a methodology based on genetic algorithms (GAs) is developed for the optimal
synthesis of multipass heat exchanger networks (HENs). The network model is based on a …

In many industrial processes, heat exchanger networks are used to transfer heat among
more than two process streams, in which the cold streams are heated by the hot streams that …

Most of the grassroot heat exchanger network (HEN) synthesis approaches decompose the
synthesis problem into a series of three major tasks:(a) minimum utility cost calculation;(b) …

Heat exchanger network synthesis (HENS) has been one of the most extensively studied
synthesis problem in chemical engineering. The methodologies commonly used to solve a …

This paper presents a methodology for carrying out both the synthesis and the optimization
of heat exchanger networks (HEN) based on a genetic algorithm (GA) technique. The …

A sequential franiework (LP, MILP, NLP) for Heat Exchanger Network Synthesis (HENS) is
described that reduces significantly the numerical problems caused by non-linearities …
