Preparation of Petroleum Sulfomate for Tertiary Oil Recovery
-
摘要: 采用SO3膜式磺化技术,磺化了石油馏分油中的芳烃,磺化产物经中和、萃取和浓缩处理,以制得符合油田三次采油要求的石油磺酸盐产品。结果表明本研究制得的石油磺酸钠产品在其低浓度时,具有较低的界面张力和较好的驱油效果。Abstract: By film sulfonation with sulfur trioxide,aromatic hydrocarbon of distillate cut oil was sulfonated,and then neutralized,extracted and concentrated to form petroleum sulfonate for the tertiary oil recovery.The result shows that the petroleum sulfonate has low interfacial tension and good flooding effect at its low concentration.
