Abstract: Extracting salt is an effective method to comprehensively utilize brine from gas field，but high concentration of Ca2+ and Mg2+ can bring about inorganic scale，which can be removed by precipitation.In this course，the flocculent plays an important role.In this paper，the effect of flocculent on the properties of the calcium magnesium precipitation is studied.The result shows a anionic polyacrylamide （APAM） can be selected as the flocculent for the precipitation with the shortest settlement time and the lowest water turbidity under the condition of the temperature of 25℃ and the stirring speed of 500r/min and the flocculent amount of 50mg/L.
Key words: gas-field, precipitation, flocculation, bittern, flocculent
