摘要
为深入研究原油脱水、破乳剂与含油污水的处理,考察了高含水稳定柴油乳化液的制备工艺.结果表明:制备O/W型油水乳液,应将乳化剂分子亲水亲油性相对强度指标值控制在13.6～14.3;乳状液中乳化剂的质量分数保持在0.16%～0.21%;添加乳化剂时应根据其亲水或亲油性分别加到水中或油中;乳化过程为先高速乳化5min,再低速乳化3min;得到的乳液其稳定时间超过5d,可满足实验研究的需要.
The preparation technology of stable emulsion with high water content r in diesel oil is investigated for probing further into the treatment process of crude oil dehydration, demulsification and the treatment of oil-bearing wastewater. Results indicate that the value of HLB may be controlled in the range of 13.6~14.3 preparing the emulsion of the O/W type. At the same time, mass fraction of the emulsion should be kept in the range of 0.16%~0.21%. In addition, the emulsion may be added to the water or the oil according to its relative characteristics. The emulsion is carried out at a high speed for is 5min, then at alow speed for 3min during the preparation process. The emulsion may satisfy the demand of experimental study because it can be kept stable for more than five days.
