Laboratory Study Water-in-Oil Emulsion Performance of Iran Oil Reservoir

the chemical method of demulsification using a demulsifier is one of the most widely used methods to remove these emulsions.In this article, we are dealing with the laboratory investigations in one of Iran s oil reservoir, the effective factors for removing the emulsion with the demolition fire chemical. The results of the laboratory show that the most important factor to increase the efficiency of the demolisher is the time required to mix this chemical with oil.In the initial times of 5 and 10 minutes, the results showed that the atmosphere was not activated and no water was separated from the oil, and the emulsion still remained, with the passage of time, after 20 minutes, some water was separated from the oil and the emulsion decreased. In order to use Demolition Fire, a special laboratory test must be done, which was achieved in a timely manner. The second case is that the results show that no water is separated from the oil at concentrations of 10, 20, 30 PPM, but at 40, 50 PPM, water is separated from the oil, so the optimal injection rate of the demulsifier for the respective tank should be obtained.
