چکیده

در این تحقیق، عملکرد یک غشای پلیمری تحت فرآیند اولترافیلتراسیون آب تولید شده همراه نفت با استفاده از یک فرآیند دو مرحله‌ای مورد بررسی قرار گرفت. در مرحله اول، تاثیر پارامترهای عملیاتی مانند اختلاف فشار دو طرف غشاء، دما و سرعت جریان عرضی خوراک بر روی میزان افت فلاکس ناشی از گرفتگی غشا در طول فرآیند مورد مطالعه قرار گرفت. برای طراحی آزمایشات و بهینه‌سازی نتایج آزمایشگاهی، از آرایه متعامد (33)9 L روش تاگوچی استفاده شد. برای تعیین مهم‌ترین پارامترهای موثر بر درصد افت فلاکس ناشی از گرفتگی غشاء، روش آنالیز واریانس مورد استفاده قرار گرفت. شرایط بهینه در سطح اول فشار (bar 5/1)، سطح دوم درجه حرارت (oC 40) و سطح سوم سرعت جریان عرضی (m/s 1) به دست آمد. در مرحله دوم، عملکرد سیستم اولترافیلتراسیون توسط غشای پلیمری تحت شرایط بهینه بررسی شد و میزان پس‌زنی روغن و گریس، TSS، کدورت و TOC به ترتیب برابر 99%، 100%، 99% و 68% دست آمد. همچنین اندازه ذرات موجود در خوراک از محدوده nm 800-200 به nm 3/0-5/1 کاهش یافت.

چکیده [English]

In this paper, the performance of a polymeric membrane was studied using a two-stage ultrafiltration treatment of produced water. At first, the effects of operating parameters, i.e. transmembrane pressure, temperature, and cross flow velocity on the flux decline caused by membrane fouling were investigated. In order to design the experiments and optimize the experimental results, the L9 (33) orthogonal array of Taguchi method was used. The analysis of variance was employed to determine the most significant parameters affecting the flux decline caused by membrane fouling. The optimum conditions were found at the first level of transmembrane pressure (1.5 bar), the second level of temperature (40 °C), and the third level of cross flow velocity (1 m/s). In the second stage, the performance of ultrafiltration system by the polymeric membrane was studied under the optimum conditions, 99% oil and grease, 100% TSS, 99% turbidity, and 68% TOC removal were obtained. Moreover, the particles size of the feed decreased from the range of 200-800 nm to 1.5-3 nm
