چکیده
زمینه و هدف: پالایشگاه‌های گازی به‌عنوان یکی از بزرگترین مراکز صنعتی در تولید انرژی و فرآورده‌های شیمیایی، همواره با چالش‌های جدی در زمینه مدیریت پساب‌های تولیدی خود مواجه هستند. این پساب‌ها که حاوی ترکیبات شیمیایی، هیدروکربنی، روغنی و گاهی فلزات سنگین هستند، می‌توانند تهدیدات قابل توجهی برای محیط زیست و منابع آبی به وجود آورند. هدف از این تحقیق، تحلیل عملکرد پکیج‌های تصفیه پساب و شناسایی مشکلات موجود در فرآیندهای تصفیه، به‌ویژه نوسانات کیفیت ورودی‌ها، مشکلات فنی در تجهیزات و نبود پایش آنلاین دقیق است.
 
مواد و روش‌ها: در این مطالعه، داده‌های عملکرد واحدهای تصفیه پساب پالایشگاه‌های گازی پارس جنوبی از گزارش‌های داخلی جمع‌آوری و پارامترهایی مانندCOD ، روغن محلول و H₂S برای ارزیابی کارایی سیستم بررسی شد. پساب‌های روغنی ابتدا در واحد API و سپس در IGF با کمک مواد شیمیایی مانند Demulsifier تصفیه شدند. پساب‌های اسیدی نیز در مخازن خنثی‌سازی با تنظیم pH اصلاح و وارد مراحل بعدی تصفیه شدند. 

یافته ها: نتایج نشان می‌دهد که با وجود پیشرفت‌های قابل توجه در عملکرد پکیج‌های تصفیه، همچنان مشکلاتی مانند نوسانات ورودی و مشکلات فنی در سیستم‌های API و IGF وجود دارد که بهبود آنها می‌تواند به کاهش آلودگی‌ها و ارتقاء کیفیت آب‌های تصفیه‌شده کمک کند. این مطالعه به‌طور مؤثر بر ارتقاء عملکرد سیستم‌های تصفیه و انطباق با استانداردهای زیست‌محیطی تأکید دارد.

نتیجه گیری: کارایی سیستم تصفیه تحت‌تأثیر نوسانات ورودی و مشکلات فنی قرار دارد و ارتقای تجهیزات و پایش آنلاین می‌تواند عملکرد تصفیه را به‌طور قابل‌توجهی بهبود دهد.

چکیده English

Background and Objective: Gas refineries, as one of the largest industrial centers in the production of energy and chemical products, always face serious challenges in the management of their produced wastewater. These wastewaters, which contain chemical compounds, hydrocarbons, oils, and sometimes heavy metals, can pose significant threats to the environment and water resources. The purpose of this study is to analyze the performance of wastewater treatment packages and identify problems in the treatment processes, especially fluctuations in input quality, technical problems in equipment and lack of accurate online monitoring. 

Materials and Methods: In this study, performance data of wastewater treatment units of South Pars gas refineries were collected from internal reports and parameters such as COD, dissolved oil and H₂S were examined to evaluate the system efficiency. Oily wastewater was first treated in the API unit and then in the IGF with the help of chemicals such as Demulsifier. Acidic wastewater was also modified in neutralization tanks by adjusting pH and entered the next stages of treatment. 

Results: The results show that despite significant improvements in the performance of treatment packages, there are still problems such as input fluctuations and technical problems in the API and IGF systems, the improvement of which can help reduce pollution and improve the quality of treated water. This study effectively emphasizes improving the performance of treatment systems and compliance with environmental standards. 

Conclusion: The efficiency of the treatment system is affected by input fluctuations and technical problems, and equipment upgrades and online monitoring can significantly improve treatment performance.
