Méthodologie d'analyses énergétique et exergétique des procédés de transformation de produits dans l'industrie

Abstract : Green House Gas (GHG) emissions, the nearby Peak Oil and the increase of fossil fuel prices led France to implement a national program called Energy Economy Certificates, among other actions. This program imposes on the energy suppliers, of which EDF, to generate energy savings within their sites and within their clients. For Small and Medium-sized Industries (SMIs), the costs of thorough energy analyses might be out of their means. The goal of this thesis is to develop a methodology that limits the time and cost of the analysis, as well as the number and precision of the necessary data. Existing energy and exergy analysis methodologies were reviewed in detail, pointing out their advantages and disadvantages. A Process Energy and Exergy Analysis (PEEA) method has been developed. This method includes three steps, of which the first one, called Process Analysis (PA) is fundamental and constitutes an upstream work performed one time for every type of product. This step consists in determining the Minimal Required Energy (MRE) to transform a raw material into final product, after which the Best Transformation Process is determined. The PA was applied to several unitary industrial operations in order to demonstrate the generic and systematic factors of the method. Afterwards, the method was directly applied to the analysis of a cheese manufacturing industry. Results showed that this method is applicable for every level of energy auditing (either low or high cost energy audits), and that it allows for identification of energy efficient solutions, usually not identifiable by traditional energy analysis methods.
