تحلیل آماری و فرآیندی پتنت های ایزومریزاسیون نفتای سبک
پتنتهای تاثیرگذار در توسعه فرآیند ایزومریزاسیون نفتای سبک بصورت فنی به 5 گروه فرآیند، کاتالیست، جداسازی، راکتور و پیش تصفیه دستهبندی شدند. تحلیل آماری پتنت ها نشان داد که بیشترین تعداد پتنت در زمینه فرآیند یا کاتالیست و اکثرا توسط شرکت های UOP و شل ارائه شدهاند. در بین پتنتهای ثبت شده، پتنتهای ارائه شده توسط شرکت UOP پر مراجعهترین پتنتها میباشند. همچنین طبق نتایج بدست آمده، سه گروه کاتالیستهای آلومینیوم کلراید، زئولیتی و اکسید فلزی مانند پلاتین، پالادیوم و رودیوم روی پایهی آلومینای کلره استفاده شده است که با توجه به خوراک، شرایط عملیاتی و محصول مورد نظر، کاتالیست بهینه انتخاب میشود. تفاوت اصلی فرآیندهای پیشنهادی در نحوه ی جداسازی نرمال پارافین از ایزوپارافینها میباشد. برای جداسازی پارافین های شاخه دار از نرمال پارافینها از روشهای غربال مولکولی یا برجهای DIH (برج جداکننده ایزوهگزان) و DIP (برج جداکننده ایزوپنتان) در ورودی یا خروجی راکتور استفاده میشود.

شبیه سازی و امکان سنجی استحصال مایعات هیدروکربنی از گاز دارای رفتار میعان معکوس با استفاده از نازل های فراصوتی
در این مطالعه، نازل های فراصوتی به عنوان یک سیستم فشارقوی متراکم که قادر به جداسازی میعانات گازی از گازطبیعی می باشد، معرفی گردیده است. یکی از مهم ترین مزایای این سیستم، بازیابی فشار تا حد زیادی در ناحیه واگرای نازل، طی پدیده تراکم موج ضربه ای می باشد. از طرفی نازل های فراصوتی فاقد تجهیزات دوار می باشند و بکارگیری آنها نیازی به مصرف انرژی ندارد. برای مدل کردن و شبیهسازی جداکنندههای فراصوتی، یک دسته معادلات غیرخطی با استفاده از نرم افزارهای MATLAB و HYSYS به صورت عددی حل شدند. در این پژوهش اثر دما، فشار و دبی جریان خوراک ورودی، فشار برگشتی در خروجی نازل و رفتار جریان در داخل نازل ارزیابی شده است. نتایج کار حاضر نشان داد که جداسازی انتخابی آب و میعانات گازی با افزایش فشارورودی در دمای ثابت، افزایش دمای ورودی در فشار خروجی ثابت و کنترل فشار برگشتی امکانپذیر است.

حذف رسوبات کف مخازن نفت خام با استفاده از کنسرسیوم باکتریایی موجود در پساب پالایشگاه نفت کرمانشاه
ذخیره و نگهداری نفت خام در مخازن پالایشگاهها سبب میشود با گذشت زمان، مقدار زیادی لجن متراکم و نسبتاً جامد در کف مخازن تشکیل شده که حاوی مقادیر زیادی فلزات و هیدروکربنهای نفتی هستند که سبب خوردگی کف این مخازن میشوند. این لجن برای محیط زیست بسیار خطرناک هستند و باید پیش از تخلیه به محیط زیست بطور کامل تصفیه شوند. در این مقاله از کنسرسیوم باکتریایی موجود در پساب پالایشگاه کرمانشاه برای تصفیه لجن نفتی ته مخازن استفاده شد. جهت کشت باکتریها از محیط کشت براث استفاده شد. تأثیر دما، pH، غلظت لجن نفتی، یون فسفات، زمان ماند و رطوبت بر عملکرد فرایند تجزیه مورد بررسی قرار گرفت. نتایج نشان میدهد که میکروارگانیسمها در pH نزدیک به خنثی (5/7) بیشترین کارایی را دارند و دمای 30 درجه دمای بهینه برای فرایند است. همچنین افزایش یون فسفات و کاهش رطوبت باعث کاهش فرایند حذف هیدروکربنها میشوند.

جایگزینی واحد تقطیر نفت خام با فرایندهای چیدمانی جدید در پالایشگاه های ایران
با استفاده از فرآیندهای بهبود یافته (مانند چیدمانهای پیشرونده و توزیعشونده) میتوان میزان قابل توجهی از مصرف انرژی و آلایندههای تولیدی در فرآیند تقطیر نفت خام را کاهش داد. با این حال فرآیندهای بهبود یافته بصورت عملیاتی مورد آزمایش قرار نگرفتهاند. در این پژوهش با درنظر گرفتن هزینههای تحمیل شده به واحد پالایشگاهی به دلیل تولید آلایندهها و ضایعات زیست محیطی و انرژی مصرفی این فرآیندها نشان داده شده است که فرآیندهای بهبود یافته میتوانند به عنوان گزینه مناسبی برای واحدهای نو تاسیس مدنظر قرار گیرند. بررسی نتایج برای نمونههای نفت سبک و سنگین ایران بیانگر صرفه اقتصادی این چیدمانها و قابلیت استفاده از آنها به عنوان جایگزینی مناسب برای فرآیند سنتی تقطیر نفت خام در ایران است. درآمد ناخالص حاصل از فروش محصولات در مورد نمونه سبک نفت خام حدود 13/0 میلیون دلار و در مورد نمونه نفت سنگین 13/12 میلیون دلار افزایش را نشان میدهد.

ریفرمینگ متان با کربن دیاکسید در رآکتورهای کوپلشده حرارتی: روشی برای تولید گازسنتز همراه با کاهش نشر گازهای گلخانهای
امروزه هیدروژن و گازسنتز دو ماده اولیه بسیار مهم در صنایع نفت، گاز و پتروشیمی محسوب میشوند که نیاز به این دو ماده به طور چشمگیری روز به روز در حال افزایش است. بنابراین، تلاش برای یافتن فرآیندهای اقتصادی و دوستدار محیطزیست برای تولید این مواد، لازم و ضروری است. از مهمترین روشهای تولید گازسنتز گازیکردن زغالسنگ، تبدیل متان با بخارآب، اکسیداسیون جزئی متان، تبدیل اتوترمال متان، تبدیل متان با کربندیاکسید و فرآیند تریریفورمینگ متان میباشند. دراین مقاله، تحقیقات انجام شده در زمینه تبدیل متان با کربندیاکسید و همچنین کوپل این روش با روشهای دیگر تولید گازسنتز ارائه شده است. نتایج تحقیقات صورت گرفته نشان میدهد فرآیند تبدیل متان با کربندیاکسید به دلیل کاهش نشر گازهای گلخانهای و تولید گاز سنتزی مناسب جهت فرآیندهای پاییندستی، میتواند جایگزین مناسبی برای فرآیندهای حال حاضر مانند تبدیل متان با بخارآب باشد.

تعیین اولویت وزنی اسپولها در لولهکشی صنعتی به کمک روش مجموع وزنی ساده
با توجه به محدودیت دسترسی به لولهکشی واحدهای صنعتی در محل و همچنین با هدف تسریع در نصب لولهها، عملیات اسپولسازی در قالب فرآیند پیشساخت صورت میپذیرد. در یک تعریف ساده، اسپول به مجموعه اتصالات و قطعات متصل به آنها گفته میشود. اولویتبندی ساخت اسپولها در فرآیند پیشساخت یکی از مهمترین مراحل پروژه است. از سوی دیگر، استفاده از مدلهای پیچیده تعیین توالی عملیات که اکثرا حجیم و زمانبر هستند نیز حل مسئله را دشوار مینماید. بنابراین، ارائه یک رویکرد تصمیمگیری جهت اولویتبندی ساخت، به جهت افزایش دقت و جامعیت ضروری است. در این مقاله، ضمن بررسی اولویتهای مطرح حوزه اسپولسازی، از روشهای مجموع وزنی ساده و ارزیابی نسبی پیچیده (COPRAS) به عنوان روشهای تصمیمگیری ساده، قابل فهم و سریع در قالب حل مثال عددی صنعتی، استفاده شده است. نتایج حاصل و مقایسه آنها با مقادیر شهودی تصمیمگیرنده نشاندهنده منطقی و کاربردی بودن آنها میباشد.
