Modified hot water processing of domestic tar sands
A wide variety of domestic tar sands have been tested using a modified hot water process with diluent addition for a bitumen viscosity control. In all cases the separation efficiency could be correlated with bitumen viscosity and optimized by viscosity control. Diluent, if necessary, was mixed with broken tar sand before the digestion step. Complete and uniform dilution of bitumen has to be achieved during the pretreatment step. Tar sands have been classified into 4 types, based on bitumen viscosity. Successful processing of each tar sand type requires adjustment of the process variables. The modified hot water process can be used successfully for tar sands from groups I, II, and III resulting in high separation efficiency when proper process variables have been chosen. The modified hot water process can be applied to both low- and high-grade tar sands containing bitumen of both low and high viscosity using the same general processing strategy describes. 17 references.
