摘要: 利用Turbiscan Lab 稳定性分析仪研究了原油/甲苯混合体系的稳定性。将不同加量的沉淀剂应用于1:9 的原
油/甲苯混合体系中,通过测量原油/甲苯的透射光和背散射光强度随时间的变化,可描述混合体系中沥青的聚集和沉
淀过程,有助于分析原油不稳定性发生的机理,并定量分析了沥青聚沉过程中的颗粒粒径大小、粒径增大速率和颗粒
沉降速率等。实验表明,随着沉淀剂的加量从80.0% 增加到90.9%,混合体系中沥青的聚集速率从192.216 μm/min 增
加到5 332.120 μm/min,粒径从10.0 μm 增大为53.4 μm ,沉积速率从0.17 mm/min 增加到0.46 mm/min。

Abstract: Effect of precipitator on the stability of blend(crude oil / toluene)has been investigated with Turbiscan Lab
dispersion-stability analyzer. Experiments are performed by mixing varying content of precipitators into the blend(10%by vol.
crude oil and 90%by vol. toluene). Based on the intensity variation of the transmitted and backscattered light with time,the dynamical
precipitation and aggression process with time can be clearly described and the instability mechanisms of blend(crude
oil / toluene)can be easily studied. In addition,Turbiscan Lab dispersion-stability analyzer can be effectively to quantitatively
analyze the piratical size and aggression and precipitation rate. The results show that both aggression rate and precipitation rate
experienced substantial increased from 192.216 μm/min to 5 332.12 μm/min and from 0.17 μm/min to 0.46 μm/min,Particle
size increases from 10 μm to 53.4 μm,respectively,with percentages of precipitator content going up from 80%to 90.9%.
