Study 31 – Systemic analysis methods for improving the energy efficiency of industrial sites

Against a backdrop of efforts to reduce energy consumption and the carbon footprint, systems analysis – and in particular the Pinch method – is emerging as an effective solution for optimising energy use in industrial processes.

This methodology aims to determine the minimum amount of energy required and to optimise heat exchanger networks, whilst minimising operational and capital costs.

The Pinch method is characterised by its strategic approach, which helps to improve energy efficiency, contribute to decarbonisation and manage resources sustainably.

The main objectives include minimising energy consumption, maximising recoverable energy and reducing operating costs.

It comprises five stages, the first three of which are set out in detail in the report:

• Data collection
• Energy audit
• Overview of heat exchanger networks
• Performance evaluation
• Adjustment

The recommendations set out in this study are intended to guide stakeholders towards optimal implementation, thereby promoting significant progress in energy management, the decarbonisation of processes and industrial sustainability.
