Most of the oil produced from oil fields is paraffin-contained crude oil. Ultrasonic treatment has been proven to be good method for paraffin inhibition. In this article, it is proved, from the microscopic point of view, that ultrasonic wave can…
The waxy crude oil is cooled and the waxy crystals form a grid structure after the shutdown, which leads to a very complicated heat transfer process. The degree of temperature drop of crude oil after shutdown directly determines the formulation of…
Wax deposition in pipelines leads to pressure drop, reduced effective cross-sectional area, and blockages. Although mathematical models and experimental loops were used to model wax precipitation on pipeline surfaces, its prediction at molecular…
