Title |
Diluent-assisted hot-water processing of tar sands |
Date |
1987 |
Description |
The influence of diluent addition and temperature on bitumen viscosity of tar sands from nine locations in the U.S.A. and Canada has been investigated. Subsequently, hot-water bitumen-recovery experiments were carried out at temperatures from 33°C to 95°C. Kerosene was added as needed to maintain the bitumen viscosity within the 0.5 to 1.5 Pa s range. Separation efficiency dropped rapidly when bitumen viscosity was greater than 1.5 to 2.0 Pa s, regardless of the origin of the tar-sand samples. Processing yield also dropped significantly at temperatures below 50°C despite optimal bitumen viscosity. Two kinds of agglomerates produced during pilot-plant processing of both consolidated and mixed tarsand feeds have been characterized. Processing features regarding diluent addition are briefly discussed. |
