In this work, the effect of blending crude oils on fouling propensity was investigated to determine the extent to which the compatibility of crude oils influences fouling. Fouling testing was performed on a series of crude oil blends with diverse compatibility profiles, as measured using a titration method. For the studied blends, the results show the main driving force behind fouling seems to be related to the compatibility of the components. As the blends approached the threshold of incompatibility, higher fouling propensities were observed. After testing, spent fluids and fouling deposits were recovered and analyzed. Stability changes in the fluids after the fouling tests were evaluated using titration measurements. These results showed that the stability of the blends increased after the runs, indicating a decrease in the solubility of the asphaltenes during fouling testing. These changes in the fluid are associated with thermal degradation of the fluid and are also evident in the deposits’ characteristics. Although compatibility seems to dominate fouling in these blends, results also revealed that there is an underlying complex behavior that requires further investigation based on detailed analysis of the samples.

原油结垢行为调查
在这项工作中，研究了混合原油对结垢倾向的影响，以确定原油的相容性对结垢的影响程度。结垢测试是对一系列具有不同相容性的原油混合物进行的，使用滴定法测量。对于所研究的混合物，结果表明结垢的主要驱动力似乎与组分的相容性有关。随着共混物接近不相容性阈值，观察到更高的结垢倾向。测试后，回收和分析用过的液体和污垢沉积物。使用滴定测量评估结垢测试后流体的稳定性变化。这些结果表明，共混物的稳定性在运行后增加，表明在结垢测试期间沥青质的溶解度降低。流体的这些变化与流体的热降解有关，并且在沉积物的特征中也很明显。尽管相容性似乎在这些混合物中占主导地位，但结果还表明，存在潜在的复杂行为，需要基于对样品的详细分析进行进一步调查。
