Investigation of the Pre-Treatment for Reducing Salt and Sediments in Khurmala Oil Field
Oil produced in most of the oil fields is accompanied by water in the form of an emulsion that must be treated. This water normally contains dissolved salts, principally chlorides of sodium, calcium, and magnesium. If crude oil is left without treatment, the salt will cause various operational problems. This research investigates experimentally the effect of major factors on the efficiency of the desalting process for a Khurmala crude oil in Kurdistan Region. These factors are chemical treatment, PH value of water, temperature and pressure drop. One of the factors is systematically varied when the others are constant and the efficiency is analyzed. It was found that the best desalter efficiency can be concluded when the embreak dosage is 100 ppm, PH of wash water 6.5 in average, the optimum temperature is 55°C and pressure drop of mixing valve is 1.5 bars and the best desalter efficiency was in acidified condition.
