[ 1 ] - Kinetic study of the regeneration of spent caustic via the genetic algorithm method
Background: Spent caustic contains noxious components such as sulfide species and also high chemical oxygen demand content (COD). Oxidation of these materials to caustic and sulfate species is mostly the rate-controlling step within catalytic oxidation of spent caustic. Methods: In this study, the kinetics of catalytic oxidation of spent caustic and the regeneration methodology of the sulfidic...
[ 2 ] - Techno-economic Analysis of Small Scale Electricity Generation from the Lignocellulosic Biomass
In this study, the techno-economic analysis of lignocellulosic biomass conversion to electricity in a small scale power plant was conducted. The proposed process is based on the thermal pathway of electricity production from a carbon content feed. Woods, forest and agricultural residues were considered as the biomass feed, which are available extensively in Iran. Besides, the process benefits n...
[ 3 ] - Evaluating the Products Quality of the Vacuum Distillation Unit by Using MFCA Method
The distillation unit is one of the main units in refning companies, and it serves as the mother unit in any refnery with any degree of complexity. The optimization of this unit can increase productivity. In this study, the vacuum distillation unit of a refnery was selected as the case study. The shares of different expenses of this unit were clarifed using a novel material flow cost accoun...
[ 4 ] - بررسی روش‌های کاهش مقدار روغن سبز در واحد بنزینسازی شرکت‌های پالایش نفت
فراوردۀ بنزین به‌عنوان یکی از محصولات با ارزش افزودۀ بالا در سبد محصولات پالایشگاهی مورد توجه بسیار است. تولید هرچه بیشتر این فراورده با توجه به مسائل مختلف کشور به یک امر حیاتی تبدیل شده است؛ امروزه بعضی از واحدهای بنزینسازی، تحت شعاع تولید روغن سبز در واحد هستند. روغن سبز ماده‌ای با گران‌رَوی و نقطۀ جوش بالا است که در داخل لوله‌ها، کمپرسور و واکنشگاه‌ها رسوب کرده، عملیات فرایندی را مختل م...
