چکیده

امروزه مزایای اقتصادی، زیست­محیطی و فنی به عنوان یک رویکرد مناسب برای سیستم­های تولید همزمان بوده و رویکرد استفاده از گرمای اتلافی برای این سیستم­ها ارزش خود را بیش از پیش نشان می­دهد. در این مطالعه سیستم تولید همزمان متشکل از چرخه برایتون فوق­بحرانی دی­اکسید­کربن، چرخه رانکین آلی، الکترولایزر غشاء پروتونی و واحد اسمز معکوس است. ابتدا تحلیل انرژی و اگزرژی روی سیستم پیشنهادی انجام پذیرفته است، در ادامه روی این سیستم پیشنهادی مطالعه پارامتری انجام شده و در نهایت از دیدگاه بیشترین توان خالص چرخه، مورد بهینه­سازی قرار گرفته است. نتایج بهینه­سازی نشان می­دهد که مقادیر توان خالص تولیدی، بازده­های حرارتی و اگزرژی، هیدروژن تولیدی و آب شیرین­شده به ترتیب 252366 کیلووات، 1/43 درصد، 37/58 درصد، 13/12 کیلوگرم بر ساعت و 52/55 کیلوگرم بر ثانیه می­باشد. همچنین سیستم تولید همزمان پیشنهادی، دارای نتایج بهتری از دیدگاه بازده قانون اول نسبت به مطالعه پیشین می­باشد.
