摘要/Abstract

摘要：

含油污泥黏度高，流动性差，是含油污泥中油分回收资源化利用的关键瓶颈。基于含油污泥的黏度和流变特性，研究了添加微乳液降低油泥黏度的方法。探讨了微乳液添加量、表面活性剂种类、表面活性剂复配对降黏效果的影响。结果表明，对于所研究的炼化含油污泥，微乳液添加量为25%时，黏度可以降低95%以上，且微乳液可以和油泥均匀混合无分层。微乳液选用单一的表面活性剂时，十二烷基苯磺酸钠（SDBS）的降黏效果最好。当烷基酚聚氧乙烯醚（OP-10）和SDBS按2：1的比例复配且添加量为25%时，黏度可以降低99%以上，降黏效果要优于两者单独使用的效果。

Abstract:

In order to reduce the viscosity of petroleum sludge for oil recovery, a micro-emulsion method was studied based on its rheological behavior. The effects of surfactant, micro-emulsion dosage and composition on the viscosity were discussed. The results indicated that the petroleum sludge could be classified as pseudo-plastic fluid and its strong shear-thinning force was attributed to the high content of solid particles in the petroleum sludge. The rheological behavior of petroleum sludge could be described by the P-L model. The results showed that the micro-emulsion could well mix with petroleum sludge and viscosity of the sludge was reduced by more than 95% by adding 25% micro-emulsion by mass. The maximum viscosity reduction was achieved by using sodium dodecyl benzene sulfonate (SDBS) as single surfactant. A viscosity reduction of 99% was obtained with the composited surfactant of OP-10 and SDBS at a ratio of 2:1.
