【 摘 要 】

In this paper, the modification of an olefin plant was performed and its refrigeration cycles were optimized using the exergy concept combined with a pinch-based approach. By the combined pinch and exergy analysis (CPEA), the present research corrected the temperature levels of the refrigeration cycles of an olefin plant to minimize exergy loss in the network and to economically and efficiently reduce shaft work demand and energy consumption in these cycles.The application results of CPEA in the olefin plant showed that its power consumption could be reduced by 2553 kW with a reasonable investment and payback period time.
