Pipeline thermodynamic analysis

Exergoeconomic analysis of dual purpose plant is presented. The thermodynamic properties and cost flow of various streams in the hybrid pipeline gas station and desalination systems are determined in Table 4 and 5 (Fig. 1). Exergy destruction for the hybrid components are determined based on the derived equations. Fig. 2. As can be observed the highest amount of exergy destruction is related to the combustion chamber. 

The case study is related to Dehshir and Kashan pipeline gas stations in Iran Gas Trunk line 8. The simulation has been performed in Thermoflex Software. Also, the Matlab code has been developed for thermodynamic simulation and exergoeconomic analysis of different scenarios. Finally, the thermodynamic, economics and exergoeconomic parameters for integration of the different cooling systems were calculated and compared. 

In this paper. The simulation has been performed in Thermoflex Software for thermodynamic simulation and analysis of Dehshir and Kashan pipeline gas station with different inlet air cooling systems. The elfeet of cooling technology on the net power capacity enhancement for the Dehshir gas stations is shown in Fig. 2. It shows the effect of cooling when the air is cooled from its ambient dry bulb temperature to 5 C by Chillers and to the Lowest Possible Temperatures with Evaporative Cooling (85% Approach) and Fogging (98% Approach).
