دراسة تأثير بعض العوامل على ترسيب شوارد الكالسيوم من المياه المرافقة لإنتاج النفط الخام في حقل العمر

To investigate the possibility of removing over hardness of produced water at Al-Omar's field by using TriSodium phosphate, variations of removal yield, function as contact time, and PH and temperature at different concentrations of, calcium and magnesium have been studied. Results of this research show that at, the rate of calcium precipitation is 100%, when mixing time and the time of equation is one hour. There is not a significant effect of pH and temperature, whereas the rate of precipitation decreases when the magnesium concentration increases.
