Premises for a combined Exergy and Pinch Optimization within ProSimPlus® simulator

The recent increase in fossil fuel prices and the more and more stringent environmental regulations have stimulated the search for further improvements. A short term and sustainable solution consists in improving energy efficiency of industrial processes. To tackle this challenge, a combined exergy and Pinch Analysis has been developed for industrial process' optimization. To summarize the presented methodology, the Exergy Analysis firstly aims at making a diagnosis of the existing process by identifying the major inefficiencies; then based upon this diagnosis; the Pinch Analysis enables to give concrete solutions to improve its energy efficiency. Moreover, the strength of this work relies in the implementation of this Exergy Analysis and Pinch Analysis methodologies in the process simulation software ProSimPlus® which provides an efficient support to the engineer.
