Tetrahydrofurfuryl alcohol (THFA) is a widely used solvent. It is a preferred solvent since it is derived from biomass. Multiple patents have reported that adding THFA during heavy oil processing improves the efficiency of the process and increases the yield. One patent for instance reported that...

The spontaneous displacement of a fluid in another immiscible one on a solid surface is essential for many technical applications, such as painting, detergency, bitumen extraction and enhancing oil recovery. This project was motivated by exploring a process of high viscosity bitumen displaced by...
