Development of a New Method for Reducing the Loss of Light Hydrocarbons at Breather Valve of Oil Tanks

Abstract

This work including, the possibility of reducing the loss of light hydrocarbons by introducing micro-quantities of an additive having surface-active properties as new method. There have been successful attempt to use free fatty acid (FFA) on the form of artificial salt to reduce the loss of light hydrocarbons. The optimal concentration of this salt was determined by estimating the lowest pressure saturated with steam its (8 mg/kg). It was found that the evaporation rate reduced to 47% in the oil tanks. It has been observed that the effect of adding this compound to the oil tank is to be slightly, it was also found that the presence of artificial salt compound at the bottom of the tank is 10%. In this case, it appeared to be advantageous to use this method for reduce the loss of light hydrocarbons, which should prevent the loss of light hydrocarbons.
