Beside entrance of oil products, water emulsions also added to storage tanks by pipeline which reduces thedistribution quality of oil products, and causes corrosion of tanks and accelerating the formation of sludge. In addition,due to its higher density,transfer of this emulsion to the vehicles and heavy machinery, will disable mechanical engines and reduce their efficiencies. In this study, with support of NIOPDC, water emulsions will remove from oil products such as gasoline using adsorbents such as carbon adsorbent, which ultimately causes reduction of maintenance costs and also increase of the economic benefits.In experiments conducted in this article, water emulsion with gasoline by concentration of 600 ppm and 0.632gr/lit of activated carbon hashighest slope in water separation present diagram and it is the most suitable proposed separation condition. With increase in amount of activated carbon to .0623 gr/lit and water emulsions to 800 ppm,waterseparation percent by activated carbon, will reach to 87 percent. On the other hand, the most appropriate recommended amount of activated carbon in 300 ppm and 600 ppmconcentration of water emulsion with gasoil are respectively 4.984 gr/lit and 0.623 gr/lit that in this statewater separation percent are respectively 73.2% and 72.38 %.
