يُعدّ النفط الخام ومشتقاته من أهم مصادر الطاقة ودعم للاقتصاد المحلي. ولذلك، يُركّز الاهتمام على تطوير صناعة البترول، بما في ذلك فصل خليط الهيبتان العادي والتولوين، الشائع في عمليات الفصل والتكرير في مصافي البترول، وخاصةً في فصل المذيبات العضوية. ونظرًا لأهمية هاتين المادتين في الصناعة الكيميائية، يُعدّ فصلهما أمرًا بالغ الأهمية. في هذا البحث، استُخدم برنامج Aspen Hysys لمحاكاة فصل هاتين المادتين من خلال تصميم برجي تقطير باستخدام مذيب عضوي مناسب، وهو N-ميثيل-2-بيروليدون (NMP)، بواقع 14 و10 مراحل فصل على التوالي. وقد كان هذا ضروريًا نظرًا لصعوبة الفصل ووجود حالة متجانسة في خليط التولوين/الهيبتان العادي. في هذه العملية، يتم ضخ ما يقرب من 962 كجم/ساعة من الخليط، بتركيز 50% لكل مادة، إلى برج التقطير ومعالجته بمذيب بمعدل تدفق دوري يبلغ حوالي 2947 كجم/ساعة، مما ينتج عنه ما يقرب من 460 كجم/ساعة من التولوين بتركيز 99.9%.
