Thermal characteristics of waxy crude oil during its static cooling in an overhead pipeline 1. Introduction. Waxy crude oil is the main kind of crude oil produced in China, 2. Physical models. The research object is an overhead crude oil pipeline transporting waxy crude 3. Mathematical
Waxy crude oils are, at low temperatures, highly non-Newtonian fluids. The crystallization of wax seems to be the cause of their non-Newtonian behavior. Moreover, the flow properties show time-dependence indicating an evolution of the structure with continued shear (termed “thixotropy”). Waxy crude oils are highly non‐Newtonian materials known to cause handling and pipelining difficulties and whose flow properties are time‐ and history‐dependent. Title: Flow characteristics of waxy crude oils; Application to pipeline design Waxy crude oils are highly non-Newtonian materials known to cause handling and pipelining difficulties and whose flow properties are time- and history-dependent. The increased flow of latent heat during the crystallization of the waxy crude oil paraffins (approximately 8 mW) compared with the non-waxy crude oil (approximately 1 mW for the WAT and 2 mW for the second crystallization event) results in a much larger area, which indicates a large mass of crystallized paraffin. As the temperature is lowered both the yield stress and plastic viscosity increase in case of each crude oil. However, the magnitude is dependent on the nature of the crude oil.

Introduction. Waxy crude oil is the main kind of crude oil produced in China, 2. Physical models. The research object is an overhead crude oil pipeline transporting waxy crude 3. Mathematical An optimized amount of GO (1 wt %) in nanocomposite results in improved flow characteristics of crude oil, providing a notable 18 °C depression in the pour point and upto 99% reduction in its apparent viscosity (down to 0.01 Pa s).

flow assurance of waxy crude oil: physical and chemical characterization, critical temperatures and rheological behavior for the restart problem-experimental study Thesis (PDF Available The experimental research on the non-Newtonian flow characteristic of a waxy crude oil was conducted through a rotational parallel-plates rheometer system. The test temperature is about 6.5 °C higher than its gel point.
