A Survey on Mathematical Modelling of Deposition in Waxy Crude Oils

Nonlinear Rheology, Yielding, and Constitutive Modeling of Waxy Crude Oils

In this work, the rheological behavior of a group of model crude oils is experimentally studied at temperatures below their wax appearance temperature (WAT). We consider both a two-component wax-oil system and a three-component oil-water emulsion that is partially stabilized by precipitated wax. We characterize the shear-localization and yielding using a combined approach of bulk rheometry and ...

Modeling the rheological behavior of waxy crude oils as a function of flow and temperature history

Rheo-PIV Analysis of the Yielding and Flow of Model Waxy Crude Oils

Waxes are a commonly encountered precipitate that can result in gelation of crude oils and cessation of flow in pipelines. In this work we develop a model wax-oil system that exhibits rheological behavior similar to waxy crude oils encountered in production scenarios. To study the consequences of gelation on the rheology of the model system we perform simultaneous measurements of the bulk flow ...

The Study of Temperature Profile inside Wax Deposition Layer of Waxy Crude Oil in Pipeline

Taking the axial heat conduction of wax deposition layer into account, a two-dimensional heat transfer model of calculating the temperature profile inside wax deposition layer was deduced and established based on the energy balance equation, the finite difference method was used to solve this model, and the influence of axial heat conduction on the distribution law of temperature profile inside...
