Asphaltene deposition is a ubiquitous problem in crude oil exploitation, which can cause the blockage of pore throat, leading to a significant reduction of oil recovery. Understanding the microscopic mechanism of asphaltene deposition and its…
After surface adhesion apparatus (SAA) experiments, the mass of oil sticking to wall was found to increase slightly in high-temperature region (70-60 °C), while this mass was increased immediately in low-temperature region (35-25 °C). The contact…
Flexible electronic devices (FEDs) based on hydrogels are attracting increasing interest, but the fabrication of hydrogels for FEDs with adhesiveness and high robustness in harsh-temperature conditions and long-term use remains a challenge. Herein,…
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.…
Superamphiphobic materials are helping with urgent issues due to increasing industrial oil transportation, as well as common oil pollution, which has triggered large interest owing to their high application value and practicability. However, they are…
The aim of this study was to investigate the effects of storage time on physicochemical properties of oleogels from high oleic sunflower oil and monoglycerides (6.6wt%). Oleogels were stored for eight weeks at 5C and tested weekly. The analyzed…
In this study, acetone fractionation was used to increase the homogeneity of softwood kraft lignin for product development. The acetone soluble and insoluble fractions were analyzed in terms of elemental composition, chemical structure, and thermal…
Understanding the structure-property relationships of the binder-aggregate interface at the molecular level provides insights into the nature of their adhesion and could pave the way for better asphalt mixtures. In this study, molecular dynamic…
The importance of manufacturing of hydrogen fuel tanks due to the application of hydrogen fuels in clean and recyclable energy is one of the most important issues of substituting the petroleum fuels. They consist of two main parts: Plastic liner, as…
Performance of the nanoparticle-modified asphalt binder is greatly influenced by adhesion properties between asphalt binder and nanoparticle. In this work, the adhesion properties of crude oil fractions (e.g., Saturate, Asphaltene, Resin and Aromatic…

During sub-sea oil spills to the marine environment, oil droplets will rise towards the sea surface at a rate determined by their density and diameter as well as the vertical turbulence in the water. Micro-droplets (< 50 µm) are expected to have…
After the start of the flow in a home-built flow-loop, the thickness of a waxy layer deposited on a stainless steel (SS) test section was found to increase immediately, while deposition was delayed for around 4 h on a polyethylene (PE) test section.…
The mechanisms by which hydrates deposit in a petroleum production-line are probably related to pipeline surface properties, e.g. pipeline material, surface energy and roughness. In this work, the wettability alteration of pipeline surfaces from…
