The ability of pinch technology to provide a general approach to process design and analysis, but it is incapable of analyzing systems that include power in addition to heat. On the other hand, exergy analysis The main limitation of exergy analysis is the lack of a comprehensive system design method. The combined analysis of punch and exergy, obtained from combining the two mentioned methods, uses both methods to remove both methods’ limitations. In this article, by introducing the Ahvaz Ramin power plant as the studied power plant, an attempt has been made to identify and examine effective improvements using the CPEA(Combined pinch and Exergy Analysis) method. Three proposed correction scenarios have been used to optimize the power plant: 1- Approaching the pins, 2- Increasing the steam in the boiler 3- Decreasing the condenser pressure. The results show that it is possible to increase the studied power plant’s efficiency by about 1.7% by using this method. The fuel consumption of 1569 cubic meters per hour reduces emissions by about 1.7 percent (equivalent to 20 tons per hour). Therefore, the production of pollutants is significantly reduced. Thermoflow software (Steam Pro) simulated the power plant and Aspen Pinch software for CPEA analysis.
