“…The results of the exergy analysis were then fed into a pinch analysis to evaluate possible thermal improvement solutions, which could result in a higher overall energy efficiency. The simplicity and practicality of this combined approach resulted in the tool being easily applied to multiple cases such as an industrial pulp and paper process, a cogeneration system, chlorine‐caustic soda, and ethylene oxide production processes. Following advances in this combined methodology, Gourmelon recently added a case‐based reasoning system to the methodology to account for the need of an experienced user to propose improvement solutions.…”

This paper presents a case study on improving the energy integration of a gasbased ethylene process by focusing on major sources of thermal exergy losses.Exergy analysis is used to find the main sources of thermal exergetic inefficiency. Thermal solutions are then developed, leading to a comprehensive list of cold and hot process streams that could potentially reduce exergy losses from these sources. Pinch analysis is then carried out to screen these streams so only those, which can minimize the energy requirement, are maintained.Besides this, pinch analysis is used to select utilities and to explore cogeneration potential. Thus, the methodology used in this paper takes advantage of both exergy and pinch analyses, in a way that all the possible thermal solutions supported by exergy analysis are considered, preventing exclusion of any hot or cold process stream with high potential for heat integration during pinch analysis.
