摘要
采用均匀设计与调优软件进行了重油乳化剂配方实验方案的设计和实验结果的优化。通过两次优化设计的方法 ,较快地取得了最佳配方。实验结果表明 ,阳离子表面活性剂与阴离子表面活性剂复配容易生成不具有表面活性的物质 ,故不宜一同使用。阳离子表面活性剂与非离子表面活性剂复配制得的乳化剂性能较好。乳化剂最佳配方为氯化十八烷基二甲基苄基铵 70mg,聚氧乙烯失水山梨醇单月桂酸酯 7mg ,失水山梨醇单硬脂酸酯 7mg ,乳酸乙酯 36mg(共占乳化油总质量的 0 12 % )。可使燕山石油化工公司产运动黏度ν10 0 =12 0mm2 /s的重油在油水质量比为 70∶30时形成的油包水型乳化重油在 80℃下稳定 3d(72h)以上 ,常温下稳定 1a以上。不同重油乳化稳定性的差别较大。
Uniform design and optimization software were used for the design of experimental plans and the optimization of the results of formulation of the heavy oil emulsifier.Through the use of the method of two times optimization design,the optimization result was obtained more quickly.The result showed that anionic and cationic type surfactants would form a substance having no surface activity,and could not be used together.The composite emulsifier prepared from cationic type and nonionic type surfactants was good for heavy oil.The optimized emulsifier formula was:benzyldimethyloctadecylammonium chloride 70 mg,Tween 20 7 mg,Span 60 7 mg and ethyl lactate 36 mg(total 0.12% of the emulsion oil).A w/o type emulsion of heavy oil with the ratio of oil:water equal to 70∶30 was stable more than 3 d (72 h) at 80 ℃ and one year at ambient temperature.The emulsion stability of heavy oils from different resources was dissimilar.
