Directional self-transportation of tiny droplets is significant in many fields. However, almost all existing studies focus on the phenomenon in air, and to realize similar performance in complex environments, such as oil, is still extremely rare.…
Efficient cleanup of viscous crude oil spill is a worldwide challenge due to its sluggish flowability at room temperature. Conventional oil remediation methods using physical absorbers, skimmers, and vacuum technologies either demonstrate low…
Abstract: Viscosity reduction is one of the key issues for heavy oil reservoir development and its transportation. Up to now, the mechanisms for ultrasonic viscosity reduction still remain unclear, especially for that of heavy crude oil which needs…
The highly viscous property of heavy oil often causes problems in its transportation in pipelines. Mixing heavy oil with light oil as well as ultrasound treatment are viable solutions to this problem. In this study, extra heavy crude oil samples were…
Separating produced water is a key part of production processing for most crude oils. It is required for quality reasons, and to avoid unnecessary transportation costs and prevent pipework corrosion rates caused by soluble salts present in the water.…
After the quinoline insoluble fraction was removed, petroleum pitch (PP) was brominated under ultraviolet light irradiation for 3 to 9 h with a bromine to PP mass ratio of 1:20 to prepare brominated PPs (BPPs). Synthetic pitches (SPs) were produced…
The rapid and effective separation of high-viscosity heavy crude oil from seawater is a worldwide challenge. Herein, an ultralow density, photothermal, superhydrophobic, and thermally conductive polyurethane/polyaniline/hexagonal boron…
This study aims to investigate a new method of combining ultrasonic waves with different frequencies and magnetic nanoparticles in reducing the asphaltene content and kinematic viscosity of heavy oil. In general, the experiments included irradiation…
