procedure for the production of bitumen from tar sand

A rapid method for the determination of bitumen, water ...

6 · A simple and rapid method has been developed to measure the bitumen, water, and solids content of Athabasca oil sand samples in order to efficiently serve both plant operations and research needs. A solvent blend of 74% toluene and 26% isopropyl alcohol extracts both the bitumen and the water from the solids producing a homogeneous liquid phase.

Oil sand is mixed with steam and water in a tumbler to produce a slurry. The slurry is then transferred to the immersed portion of an apertured inclined surface in a water bath. The inclined surface may be in the form of a rotating drum, a tilted rotating dish or an inclined moving endless conveyor belt. The sand particles drop through the apertures and are collected from the base of the bath ...

Bitumen Recovery

James G. Speight PhD, DSc, in Oil Sand Production Processes, 2013. 3.4 Other Processes. It is conceivable that the problems related to bitumen mining and bitumen recovery for the oil sand may be alleviated somewhat by the development of process options that require considerably less water in the sand/bitumen separation step. Such an option would allow a more gradual removal of the tailings ponds.
