This paper presents a two-stage procedure for the optimal redesign problem of existing heat
exchanger networks. In the first stage, a mixed-integer linear programming (MILP) model is …

Heat Exchanger Network (HEN) synthesis is an important field of study in process
engineering. However, obtaining optimal HEN design is a complex task. When …

This paper presents a systematic procedure for the retrofit design of heat-exchanger
networks (HEN's). The approach is divided into a prescreening stage and an optimization …

This paper addresses the problem of synthesizing heat exchanger networks that have the
flexibility of coping with prespecified changes in flow rates, inlet temperatures and outlet …

In this paper, a new global optimization approach for the synthesis of heat exchanger
networks is presented. The Synheat model by [Comp. Chem. Eng. 1 (1990) 1165] uses a …

A thermochemical based process superstructure and its mixed-integer nonlinear
optimization (MINLP) model are introduced to convert biomass (switchgrass), coal (Illinois# …

The methodology presented in the paper combines insights from Water Pinch with
mathematical programming. The approach applies to mass exchanger network and …

This study presents developed approaches that could be used for retrofitting of existing heat
exchanger networks (HENs) within individual processes and industrial sites to achieve lower …

This study presents a new hybrid methodology for synthesis of cost-optimal heat exchanger
networks (HENs). The problem is solved in a two-level approach. The upper level generates …

In this paper, an efficient as well as reliable approach to deal with heat exchanger networks
(HENs) synthesis problems, which is inherently known as a mixed-integer non-linear …
