Abstract
Effect of solid paraffin on crude oil rheology was investigated. The experiments were carried out on model-crude oil at constant temperature 30?C. Medical paraffin malting point of 61 ?C different concentration was dissolved in kerosene fraction. Concentration range of paraffin was from 1 to 32% weight. Shear stress strongly depends on paraffin's content only over high shear rate. Shear stress increases exponentially with increasing paraffin concentration for high shear rate. This dependence does not existed for real crude oil investigated in this paper.
