Abstract: In the current study, energy, exergy, economic and environmental (4E) analysis for a multi-effect desalination plant with and without feed brine preheater integrated with a steam boiler and solar hybrid system for three coastal cities of southern Iran during a year is investigated. Four main configurations of hybrid/MED-TVC, hybrid/MED-TVC.FH, boiler/MED-TVC and boiler/MED-TVC.FH are considered. By using artificial bee colony algorithm, systems were optimised. The results show that: using feed brine preheater, the unit cost reduced by 6.5% for the system with a boiler and 3.8% for the hybrid system.
Keywords: solar energy; MED-TVC.FH; CO2 emission; ABC algorithm; 4E analysis.
