- Abstract:
- By analyzing the physical properties of produced water from an oilfield in Iraq, the difficulties of water quality stability and purification are found out. Combined with the characteristics of oilfield produced water, the experimental researches on corrosion control, scaling control of gas stripping desulfurization tower and selection of reagent system are carried out. Through simulation calculation, sulfur resistant corrosion materials are selected, and the acid-base adjustable gas stripping desulfurization process is added to the conventional produced water treatment process to reduce the power consumption. Finally, the closed treatment process flow of regulation and storage buffer, coalescence oil removal, coagulation sedimentation, gas stripping desulfurization and two-stage filtration was determined. After treatment, the purified water met the requirements of oilfield water injection, that is, oil≤5 mg/L, SS≤5 mg/L, H2S≤20 mg/L.
