| The current practice of transporting bitumens by pipeline through the addition of a C;The MTBE and the TAME appeared completely soluble in the bitumens and were successful in reducing its viscosity to meet pipeline specifications. The methanol and iso-propanol remained insoluble in the bitumens.;The effect of the alternative solvents on the rheology of bitumens was studied along with the aspect of solvent distillation. The possibility of encountering asphaltene separation is considered. Also, a number of liquid-mixture viscosity models were evaluated. |
