المستخلص:
عمليات الحفر تنتج كميات كبيرة من الماء الملوث يعرف بالماء المنتج او الماء المنتج من البئر. مختبريا تم التحقق باستخدام Autoclave بحجم لتر واحد مصنوع من مادة الصلب stainless steel لمعالجة الماء المنتج من حقول الرميلة الشمالية والزبير الخطوة الاولى استخدمت م | The oil drilling operations create large quantities of contaminated water known as “Produced Water” (PW), or water that is produced from the well. An experimental investigation was conducted using 1litter stainless steel autoclave to treat the oily water produced from North Rumaila and Zubair oil fields. The first approach was a pretreatment to remove solid particles using sedimentation with and without flocculation. The second approach included studied the effect of pH, pressure, temperature, salinity, operation time, outlet time and RPM. The third approach was investigate the effect of the surfactants (detergents and alcohol) to reduce surface tension, finally, was addition of some sorbents like polypropylene, polyethylene, used plastic and sawdust.The ranges of salinity, pH, pressure and temperature were selected according to the PW conditions which out from dehydrator and desalter (80000 ppm, 6, 3bar and 60°C respectively), the RPM of mixer was selected to satisfy laminar flow, while the time of operation and outlet product represented the minimum residence time in batch reactor and its discharge to choose the minimum design cost. The results showed that the best conditions were : - Pressure =1 bar, temperature =45°C, mixer speed =300 RPM, treating time =15 min and skim time starting =5 minutes. Best additives to reduce surface tension : ethanol volume = 0.05vol %, powder detergent = 400 mg/litter and liquid detergent volume = 0.03vol%. Best sorbents : Sawdust amount addition = 2.5 gm, polypropylene = 4 gm, polyethylene = 3 gm and used plastic = 2.5 gm The results showed that using polymers made a great change in the oil recovery percent (all the oil was recovered).
