The analysis justifies that the hydraulic properties of pipelines collecting and transporting difficult-to-decompose oil emulsions should be taken into account for their calculation and increasing operational efficiency of the pipelines. The structural sustainability of water-oil emulsions in various temperatures and watercut degrees of oils in technological pipelines based on the study of abnormal rheological properties have been analyzed. It was defined that these systems with relaxation behavior as well in the motion through the pipelines may lose the structural stability. It was revealed that the transition to the turbulent mode of oil emulsions with various watercut degrees takes place in the generalized Reynolds number Re * = 1200.

Glycerol Monooleate

The objective of this study was to characterize the flow and rheological behaviour of model wax-stabilized water-in-oil (W/O) emulsions consisting of light mineral oil, paraffin wax and glycerol monooleate as the oil phase and water as the dispersed aqueous phase. An[sic] laboratory-scale benchtop flowloop system was used to explore the flow behaviour of the emulsions' oil phase (oil, paraffin wax and surfactant). The key contribution from this work was that the higher initial temperature gradient (40°C compared to 19°C) experienced by the rapidly-cooled oil led to more initial deposition on the flowloop inner wall. The rheological properties of W/O emulsions with different water cuts (10-50wt%) were also studied. Rotational, oscillatory rheology and creep compliance and recovery were characterized on emulsions aged up to 28 days. Overall, the results demonstrated that emulsion composition, and age could significantly influence an emulsion's flow behaviour and rheological properties.
