Abstract: (119 Views) |
The global population growth and human lifestyle transformation have escalated the need for fresh water and energy, a challenge which can be tackled by using industrial desalination facilities. The research innovation of this study is to determine the feasibility of integrating Shahid Salimi Neka Combined Cycle Power Plant (CCPP) (Neka County, Mazandaran Province, Iran) with multiple-effect distillation and reverse osmosis (MED-RO) facilities through a conventional comprehensive analysis as well as advanced analyses of exergy, economic exergy, and environmental exergy. For this purpose, mathematical programming is first used for thermodynamic CCPP modeling. After that, a mathematical model is proposed to integrate the existing CCPP into MED-RO facilities. Finally, the foregoing conventional and advanced analyses are conducted to evaluate the primary performance parameters of the integrated CCPP–MED-RO system and identify potentially technical, economic, and environmental advances. The results indicated a 3.79% increase in fuel consumption after the CCPP was integrated with desalination facilities. The exergy efficiency of the advanced system was reported 42.7%, and the maximum cost of the combustion chamber exergy destruction was estimated at $1.09 per second. According to economic and environmental analyses of the integrated system, gas turbines would have the highest investment cost (i.e., $0.047 per second), whereas the MED system would have the maximum environmental impact factor (i.e., 0.025 points per second).
