  7. Abstract:
  8. Oil/water separation is an important field, not only for scientific research, but also for environmental, economic, and social issues. On the one hand, oily wastewater, resulting from industries such as steel, aluminum, food, textile, leather, petrochemical and metal finishing, has become the most common pollutant all over the world. On the other hand, frequent oil spill accidents are of great concern since the discharge can lead not only to serious environmental pollution, but also a great loss of energy.
    In crude oil removing water is necessary due to reducing corrosion, increasing thermal values of fuels obtained from crude oil, preventing catalists from destruction by water and reducing the volume of oil befor transfer. Numerical simulation is very useful in research about fluid motion within the membrane pores. In the Numerical simulation, movement of water and oil droplets within pores could be easily observed and various objects could be independently researched. In this research, we have been studying the simulation of fluid passes through the membrane and the effects of various factors on quality of separation of oil and water. The effects of geometry, non-Newtonian fluid and being 3d have been studied. We have found the optimum condition for geometry, the difference in behavior of non-Newtonian fluid and Newtonian fluid and the difference and similarities of 3d and 2d simulations
