摘要
原料油直接影响到石油磺酸盐产品的成分及性能指标。采用实验室直接合成石油磺酸盐的方法对收集到的9种石油馏分油进行原料油的筛选研究。对合成出来的石油磺酸盐产品进行酸渣量、未磺化油、收率、界面张力等测试,结果表明:由低黏度糠醛抽出油和中捷减二线油为原料油得到的石油磺酸盐单剂油水界面张力均能达到10^(-2) m N/m数量级。因此,建议低黏度糠醛抽出油和中捷减二线油作为大港油田合成石油磺酸盐的原料油。此外,针对原料油磺化过程中酸渣生成较多的问题,优化研究了稀释剂、反应温度和反应时间对磺化反应的影响,进而得出了最佳的合成条件:原料油稀释剂二氯乙烷质量分数2.0%,反应温度为55℃,反应时间为1 h。
The raw oil directly affects the components and performance index of petroleum sulfonate products. The method to directly synthesize petroleum sulfonate in lab has been used to research the screening of raw oil for 9 kinds of oil obtained from petroleum fraction. The petroleum sulfonate products so synthesized have been tested for acid sludge quantity, unsulphonic oil quantity, recovery rate and interfacial tension. The test results indicate that:the water-oil interfacial tension of petroleum sulfonate obtained by using the oil extracted from low-viscosity furfural and the oil from Zhongjie Pipeline II as raw oil can reach the magnitude of 10-2 mN/m. Therefore, it is advised to use the oil extracted from low-viscosity furfural and the oil from Zhongjie Pipeline II as the raw oil for synthesis of petroleum sulfonate in Dagang Oilifeld. In addition, aiming at the problem that too much acid sludge is generated in the course of sulfonation of raw oil, the impact by thinner, reaction temperature and reaction time on sulfonation reaction have been researched and optimized, and then the optimal synthesis conditions have been obtained:the mass fraction of raw oil thinner (dichloroethane) is 2.0%, the reaction temperature is 55℃, and the reaction time is 1 h.
