Experimental Analysis on Selection of Suitable Demulsifier for High acid Crude Oil
With the development of society,the demand for oil is increasing.The existing demulsifiers have certain limitations.For the oil-in-water emulsion with extremely high water content,the dehydration rate is low,the dehydration temperature is high,and the dehydration speed is slow.Therefore,it is very important to select suitable demulsifier for different crude oil in different regions.The effect of petroleum sulfonate on demulsifier was investigated by bottle dewatering method at 90 ℃ and 10 x 10-6 demulsifier.The results show that petroleum sulfonates significantly reduce the demulsification and dehydration of demulsifier in high acid crude oil.
