Abstract
A method and system for handling viscous liquid crude hydrocarbons is disclosed. The method involves (a) solvent deasphalting at least a portion of an asphaltene-containing liquid crude hydrocarbon feedstock to form an asphaltene fraction and a deasphalted oil (DAO) fraction essentially free of asphaltenes; (b) adjusting the density of the asphaltene fraction to substantially the same density of a carrier for the asphaltene fraction; (c) forming coated asphaltene particles from the asphaltene fraction of step (b); (d) slurrying the coated asphaltene particles with the carrier; and (e) transporting the slurry to a treatment facility or a transportation carrier.
