An improved design method for retrofitting industrial heat exchanger networks based on Pinch Analysis
TL;DR: Li et al. as discussed by the authors proposed a systematic but simple Pinch Analysis (PA)-based retrofit approach to lessen the utility consumption of any industrial heat exchanger network (HEN) under new minimum temperature approach (ΔTms) at the cost of minor capital investment.

New MILP-based iterative approach for retrofitting heat exchanger networks with conventional network structure modifications
TL;DR: In this article, the authors proposed a novel optimization approach of retrofitting heat exchanger networks for both small scale and industrial scale problems, where a simple but efficient method is proposed to determine the network retrofit superstructure based on the concept of pinching match.

Heat integration between processes: Integrated structure and MINLP model
TL;DR: The objective was to maximize the annual profit of integration between processes and retrofits and the simultaneous MINLP integration of the four processes has selected only two retrofitted ones yielding total additional profit of 1.94 MUSD/a.

New pinch technology based hen analysis methodologies for cost‐effective retrofitting
Roger Nordman,Thore Berntsson +1 more
TL;DR: In this paper, new pinch technology based curves for retrofitting of heat exchangers are presented and compared to traditional pinch curves, and the information that can be extracted from these curves, are discussed.

Retrofit of complex and energy intensive processes II: stepwise simultaneous superstructural approach
TL;DR: In this paper, an extended procedure has been employed for retrofits using a three-step approach: (i) generation of a process superstructure by pinch analysis; (ii) formulation of a mixed integer nonlinear programming (MINLP) model and its simplification into a relaxed non-linear programming model; (iii) simultaneous optimization, first by a process simulator and than by the NLP algorithm.
