“…A case study demonstrated the methodology showing a practical approach to reduce operating costs in existing systems. An extended pinch analysis and design procedure evaluating pressure based exergy for sub ambient cooling were presented by Aspelund et al [84]. They demonstrated a substantial potential for minimising energy requirements (total shaftwork) in sub ambient processes.…”

“…Therefore, it is possible to integrate both work and heat in the same network for the purpose of energy conservation (Razib et al, 2012). Aspelund et al (2007) presented a heuristic graphical method based on Extended Pinch Analysis and Design (ExPAnD) to minimize energy requirements under sub-ambient conditions. In their work, compressors and turbines are used separately, and no mention is made to the use of combinations between these pressure manipulation equipment operating on a same axis.…”

The optimal integration of work and its interaction with heat can represent large energy savings in industrial plants. This paper introduces a new optimization model for the simultaneous synthesis of work exchange networks (WENs), with heat integration for the optimal pressure recovery of process gaseous streams. The proposed approach for the WEN synthesis is analogous to the well-known problem of synthesis of heat exchanger networks In all case studies, the heat integration between WEN stages is essential to improve the pressure recovery, and to reduce the total costs involved in the process.

Pinch analysis has been known as one of the tools for smart energy management. This technique has successfully been applied in more than three decades in various industries. Here, the purpose of this study was to describe how to use pinch analysis for improving heat exchanger network design of a revamped chemical plant. In a revamping project of a chemical plant, the pinch analysis is applied to find a better design. The analysis reveals that the revamped case can be further improved to achieve more energy saving. This is done by applying one of the golden rules in pinch analysis, which is not to transfer heat across the pinch. The proposed solution is rather simple and straightforward, leading to only few months of payback period and 165 k€ per annual saving.
