Asphaltenes are a solubility class of bitumen known to have undesirable properties. As asphaltenes are insoluble in paraffinic solvents, they can be separated from bitumen by adding a solvent such as n-pentane or n-heptane to produce better quality deasphalted oil (DAO). This process is called...

In oil sands mining operations, water-based mixtures containing coarse sand grains and fine mineral solids (including clays) are ubiquitous. The clay fraction can have a detrimental effect on the separation of bitumen from the oil sand matrix, on the hydrotransport pipelines, and on water...

Strain aging of microalloyed steel pipes, manufactured for oil and gas transmission, can occur during the anti-corrosion fusion bonded epoxy coating process (180°C - 250°C) and/or during long term storage or use. The primary mechanism of strain aging involves the segregation of interstitial...

Amorphous bioactive glass powders are used as bone-filling materials in many medical applications. Bioactivity is achieved through ion exchange with bodily fluids, leading to surface apatite mineral formation – a necessity for tissue development. Traditional fabrication is by melt-casting and...

Among all the competing methods to enhance the phase separation of water-in-oil emulsions in chemical industries, electric field is considered as one of the best treatment options. To better understand the mechanism by which electric field assists water droplets coalescence and the corresponding...
