The Components of the Bitumen in Athabasca Bituminous Sand and Their Significance in the Hot Water Separation Process

Abstract: Judging from the proportions of the components and the ultimate analyses, the bitumen throughout the Athabasca bituminous sand deposit had a similar origin. Moderate variations in the proportions of the components of the bitumen in bituminous sands, which separate normally in the hot water process, do not have any effect on the separation. There is evidence that some bituminous sand beds at Bitumount contain bitumen whose components are in somewhat different proportions to each other than is the case with the bitumen in other beds in the section. The fine clay present in bitumen appears to be closely associated with the asphaltenes. A method is indicated for avoiding the formation of troublesome emulsions when determining the proportion of saponifable material in the bitumen. Differences in the relative viscosity of the bitumen would appear to be due primarily to variations in the relative proportions of the oily constituents.

The Role of Very Fine Mineral Matter in the Hot Water Separation Process as Applied to Athabasca Bituminous Sand

The clay present in bituminous sand as a natural constituent plays a key role in the hot water separation process. Some clay is necessary for satisfactory results; more than enough decreases the yield of oil. When bituminous sand is mixed and ... Show Abstract
