Abstract

Manufacturing processes are diverse by nature. Consequently, classical energy assessment of each process requires specific analyses leading to significant costs that cannot be always sustained by Small and Medium-Sized Enterprises (SME). Therefore, Abou Khalil et al. introduced in 2008 an energy and exergy analysis method called Process Energy and Exergy Analysis (PEEA) in order to systematize process energy auditing and assessment. This method is based on the best available or possible process to transform the raw material into final product, while maintaining the same (or higher) product quality and plant productivity.

Directly derived from an application of the PEEA, this paper presents a scanning and auditing tool for industrial plants. This tool aims at identifying within the industrial plant, customized and pertinent process energy efficiency improvements, while quantifying the potential energy savings as well as payback time for investments. This way, SMEs in question have the possibility to carry out, with low cost, a thorough energy diagnosis focusing on the previously identified improvements.
