This research performs the advanced exergy and exergoeconomic analyses of a combined cycle power plant (CCPP) located in Zavareh, Iran. The objective of this research is to evaluate the irreversibilities, their related cost rates of each part of the CCPP that can be avoided and the inefficiencies of each part that caused by other components. The advanced exergy and exergoeconomic analyses indic...

In this study, an integrated structure of the air separation unit, natural gas liquids recovery equipped with nitrogen removal unit is developed. In this regard, advanced exergy and exergoeconomic analyses are used to examine the irreversibility, possible improvements and the cost of the inefficiencies of the process. The exergy analysis presents information on the origin of the irreversibility...

C3MR, MFC, and DMR processes in an integrated LNG-NGL-NRU structure are investigated using the conventional and advanced exergy and exergoeconomic analyses. The results of advanced exergy analysis reveal that in most of the equipment, the highest amount of irreversibility is occurred because of endogenous exergy destruction. In C3MR process, compressor C5 with 9730 kW; in MFC process, compresso...

TThe present paper evaluates the plan of combustion air pre-heater installation on the fired heater from thermodynamics and thermos-economics point of view. As a real case study, one of the fired heaters (H_101) of Distillation unit in Tehran Oil Refinery, Iran, is intended. With applying an air pre-heater in this study, flue gases temperature falls down from 430 ºC to 200ºCand combustion a...

A conventional exergy analysis can highlight the main components having high thermodynamic inefficiencies, but cannot consider the interactions among components or the true potential for the improvement of each component. By splitting the exergy destruction into endogenous/exogenous and avoidable/unavoidable parts, the advanced exergy analysis is capable of providing additional information to c...

Advanced exergoeconomic analysis is applied on process configurations for co-production of LNG and NGL. This analysis provides information on the origin of the irreversibility as well as the irreversibility value of the process. The exergy destruction, exergy destruction cost, and also investment cost, are divided into two available/unavailable and endogenous/exogenous parts. The results of adv...

advanced exergy analysis is a tool to split the exergy destruction of the system to achieve a better perspective about the potentials of a system for improvements. in addition, the component interactions and their exergy destruction dependency with the other equipment are investigated through the advanced exergy analysis. for this purpose, it divides the exergy destruction calculated by convent...
