Abstract:
The aim of this research is to study how to treat the wastewater and sour water resulting from a petroleum refinery and to determine the characteristics of generated after treatment. The research identified the sources of wastewater pollutants, suitable treatment technologies, and its effect on the environment. Liquid waste produced was studied, the unit that used as well as to treat the waste, and the evaluation of the performance of these units. Laboratory tests were conducted to identify the characteristics of wastes in each stage and using hissy to simulate sour stripping unit to achieve high quality of purified water.
The analysis carried include: oil content, phenol content, Biochemical Oxygen Demand, Chemical Oxygen Demand, Ammonia - Dissolved Oxygen, Suspended Solid.
The results obtained revealed the following:
• The oil content can reach more than 20.000mg/l and this is more than The design capacity of the treatment unit but it can be reduced to less Than 10 mg/l after treatment.
• The waste water treatment unit works with capacity more than the Designed, so the efficiency of this unit is not enough.
• There is a lot of polluting effluent with concentration more than the Allowed (i.e. NH3, pH)
• The above indicates some design problem and the study recommended To add additional units to solve the above mentioned problems and Obstacles
