چکیده مقاله به فارسی :
اين پژوهش به شبيهسازی فرآيند تقطير استخراجی برای جداسازی اتانول از پسابهاي صنعتي حاوی آب و نمک با استفاده از حلال اتيلن گليکول در نرمافزار Aspen Plus ميپردازد. هدف اصلي، بهينهسازی پارامترهای عملياتي کليدی شامل نسبت حلال به خوراک، نسبت جريان بازگشتي و نوع سينی های ستون تقطير برای حداکثرسازی بازيابی اتانول و کاهش مصرف انرژی است. نتايج شبيهسازی با دادههای تجربي حاصل از يک ستون تقطير نيمهصنعتی اعتبارسنجی شد. مدل توانست به کارايی حذف نمک 98% دست يابد که نزديک به کارايي تجربی 96.5% است. همچنين با افزايش نسبت بازگشتی از 0.2 به 2، خلوص اتانول از 90% به بالاي 99% افزايش يافت. يکپارچهسازی حرارتی نيز منجر به کاهش 25% در مصرف انرژی شد.
