Chemical Oxidation for Oil Separation from Oilfield-Produced Water / Homogeneous Process by Batch Technique
محتوى المقالة الرئيسي
الملخص
تعتبر المياه المصاحبة للنفط من أخطر أنواع التلوث على البيئة، لأنها تحتوي على العديد من الملوثات الضارة بالبيئة وصحة الإنسان مثل (النفط، المواد الصلبة العالقة، المواد الذائبة، والعديد من الملوثات الأخرى). يتناول هذا المقال عمليات الأكسدة المتقدمة (AOPs) التي تمت دراستها لتنقية المياه المنتجة من حقل الخباز النفطي الواقع في شمال العراق - محافظة كركوك من المحتوى النفطي. نظرًا لسهولة استخدام AOPs والأداء والسعر المنخفض، فهي طريقة شائعة لتنقية هذا النوع من مياه الصرف الصحي. في هذا العمل تم استخدام عمليات التحفيز الضوئي المتجانسة (Photo-Fenton (H2O2+Fe+2+UV)،) Fenton (H2O2+Fe+2، وUltra Violet (UV) فقط) في نظام الدفعات تحت أفضل الظروف (الزمن = 120 دقيقة، الرقم الهيدروجيني = 2.5، H2O2 = 20 مل في عملية فوتو فنتون، H2O2 = 80 مل في عملية فنتون، 2 مصباح UV (قدرة كل واحد = 8 وات) في عملية فوتو فنتون، 10 مصابيح UV في عملية UV مباشرة، و Fe+2=18 مجم في عمليات فوتو فنتون وفنتون). تم في هذا البحث دراسة تأثير جرعات H2O2 وFe+2 وزمن التشعيع وقيمة الرقم الهيدروجيني وشدة الأشعة فوق البنفسجية على فعالية إزالة النفط. حققت هذه الدراسة أعلى كفاءة في الفوتو-فنتون هي 85.68%، الفنتون= 75.01%، والتحليل الضوئي فوق البنفسجي المباشر= 56.64%. ونتيجة لذلك تم التوصل إلى أن عملية الفوتو فنتون هي أفضل طريقة لإزالة النفط من المياه المصاحبة للنفط.
