摘要
使用以多重光散射技术为基础的Turbiscan稳定性分析仪,对聚山梨醇酯、烷氧基化树脂、烷氧基化树脂衍生物、多羟基树脂、聚胺衍生物等5种不同类型的破乳剂对脱水效果的影响进行了系统研究。Turbiscan获取样品整个破乳过程的透射光曲线(上图左),从透射光数据中的脱水澄清度(water clarity),脱水速度(kinetics),脱水率(amount of extracted water),油水界面质量(interface quality)四个方面研究了不同破乳剂的破乳效果。结果表明,使用多重光散射技术可以快速、精确地研究原油破乳性能;破乳剂加量在一定浓度范围内,聚山梨醇酯和烷氧基化树脂衍生物破乳剂具有最好的破乳性能(上图右)。其中聚山梨醇酯(1)具有最大的脱水率,而烷氧基化树脂衍生物(3)具有最快的脱水速度。
The effectiveness of 5 different demulsifiers is analyzed with Turbiscan,a SMLS(static multiple light scattering) principle instrument.The above graph is displays a typical Turbiscan profile obtained.The graph displayed shows information regarding the amount of produced water,the clarity of produced water,the quality of water/oil interface and the demulsification kinetics.The result showed:Turbiscan is a quick and simple method to compare the effectiveness of different demulsifiers.Polysorbate polyester(l) and Resin alkoxylate(3) display the best demulsion performance;Demulsifier lin terms of quality of separation(oil/water interface quality and clarity of produced water) and Demulsifier 3 in terms of separation kinetics and the volume of produced water.
