| پژوهش حاضر به منظور شناخت ترکیب بهینه‌ی آب شیرین کن های تبخیری چند مرحله ای با تراکم گرمایی بخار و اسمز معکوس و سیکل توربین گاز انجام شده است. در گام نخست، مدلی جامع برای بخش‌های مختلف سیکل توسعه یافته و سپس با استفاده از روش ترمواکونومیک وضعیت اقتصادی سیستم مورد بررسی قرار گرفت. ابتدا شش چیدمان برای ترکیب واحد اسمز معکوس با آب شیرین کن تبخیری چند مرحله ای تعریف شد و دو رویکرد در بهینه سازی مورد توجه قرار گرفت. در رویکرد اول تولید آب شیرین آب شیرین کن تبخیری چند مرحله‌ای ثابت و در مقدار 70000متر مکعب در روز نگهداشته می‌شود و تولید آب شیرین کن اسمز معکوس به صورت کسری از آن و در مقادیر % 75% ،50و % 100از تولید آب شیرین کن تبخیری چند مرحله‌ای در نظر گرفته می‌شود. در حالی که در رویکرد دوم تولید آب شیرین کن آب شیرین کن تبخیری چند مرحله‌ای ثابت نبوده و به منظور دستیابی به یک ارزیابی جامع و مطالعه بهتر، قیود مسأله بر تولید کل آب شیرین اعمال می گردد. نتایج نشان می‌دهد که چیدمان اولین بالاترین راندمان اگزرژی و کمترین قیمت آب شیرین را داراست. | ||

| چکیده [English] | ||
| The present study aimed to recognize the optimized configuration of hybrid multiple effect evaporation and reverse osmosis desalination and gas turbine cycle. To achieve this goal, first, a thermodynamic and thermoeconomic model was developed for different parts of the cycle. Six configuration for hybrid desalination plant were. In fact, one of the important goals of the present study was to investigate whether the integration of hybrid desalination plants is useful from thermodynamic and economical points of view. Two approaches were considered in the optimization study. In the first approach, the water production of multiple effect evaporation desalination plant was fixed at 70000 m3/ day and the capacity of reverse osmosis desalination was considered as 50%, 75% and 100% of thermal desalination capacity. In the second approach, the water production of multiple effect evaporation desalination plant was not fixed but the total production rate of hybrid desalination plant were given at 105000, 122500 and 140000 m3/day. The final conclusion showed that the first configuration could be chosen as the best one because it had the maximum value of exergy efficiency and minimum value of cost of water in both first and second optimization approaches. | ||
