A systematic framework for the synthesis and/or retrofit of flexible and structurally
controllable heat exchanger networks is presented in this paper. Based on a multiperiod …

This paper deals with the global optimization of heat exchanger networks with fixed
topology. It is shown that if linear area cost functions are assumed, as well as arithmetic …

Industrial processes typically involve heating and cooling fluids via networks of heat
exchangers which reuse excess process heat onsite. Optimally synthesising these networks …

Differential evolution (DE), a population-based direct-search algorithm, has been gaining
popularity in the recent past due to its simplicity and ability to handle nonlinear …

In this paper, the conceptual framework and applications of the State Space Approach to
Process Synthesis are presented. It is shown that the State Space Approach contains the …

The chemical process industry is a major user of energy. Energy recovery via heat
integration is a long established practice in this industry. The existing mathematical …

We present a framework for the efficient representation, generation, and modeling of
superstructures for process synthesis. First, we develop a new representation based on …

A heat exchanger network (HEN) is an important part in processing plants used to recover
heat from process streams. A utility system supplies heating and cooling utilities and …

Heat exchanger network synthesis (HENS) is still a challenging task for minimizing the Total
Annual Cost (TAC). In this work, a Cuckoo Search Algorithm (CSA) is introduced to solve the …

Process plants are often divided into logically identifiable regions, each having associated
processing tasks. Such regions are necessary when considering the practical features of …
