Abstract
The aim of this research is to study how to treat the liquid waste
resulting from a petroleum refinery and to determine the characteristics of
liquid waste generated. The research identified the sources of wastewater
pollutants, suitable treatment technologies, and its effect on the environment.
Khartoum refinery was considered as a study case, 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. The effluent drain to the
environment was studied and compared with the permissible limits .The
analysis carried include: oil content, phenol content, power of Hydrogen,
Biochemical Oxygen Demand, Chemical Oxygen Demand ,Ammonia -
Nitrogen, Sulfide, Dissolved Oxygen ,Ortho-phosphate Content, Suspended
Solid.
The results obtained revealed the following:
• The oil content can reach more than 20.000mg/l and this is more than
the deign capacity of the treatment unit but it can be reduced to less
than 10mg/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.
