Bitumen has an extremely high viscosity, between 8 and 10 API degrees (at ambient temperatures), rendering it unusable for use in electric power stations. Bitumen can be modified by mixing it with fresh water and a small amount of phenol-based surfactant. The resulting mixture has properties similar to conventional fuel oil. A newer version of bitumen-based fuel has replaced the original version with an alcohol-based s

Sep 19, 2017 Fuel oil and bitumen are residual products of oil refining At the first stage, gas is released, followed by light fractions (gasoline, kerosene, diesel fuel etc.). Fuel oil is a residue, heavy viscous fraction, but not the final one. It is also processed, to get car oils, paraffin and bitumen oil – a weakly viscous or solid substance.

Bitumen is a kind of crude oil found in natural oil sands deposits—it’s the heaviest crude oil used today. The oil sands, also known as tar sands, contain a mixture of sand, water, and oily bitumen. The tar sands region of Alberta, Canada is the third largest petroleum reserve in the world.

A mix using a PG 64-22 unmodified (no polymer added) binder, would lose 10% of its weight from a standard core sample when soaked 24 hours in jet fuel. A mix made with a standard binder grade PG 76-22 PMA binder would lose 5-6% of its weight after 24-hours. But a jet fuel resistant PMA, with 7.5% polymer would have a weight loss of less than 1.0%.

Jun 04, 2004 Viscosity and density reduction of a heavy oil or bitumen could be achieved by mixing it with a solvent. The information about the viscosity of a heavy oil/bitumen-solvent mixture is vital for designing solvent floods and for input into reservoir simulators, both for recovery processes and reserves assessment.
