Abstract: Implementations of the present disclosure relate to a method of operating a coker unit comprising the steps of: collecting a coker-furnace feed stream; introducing the coker-furnace feed-stream into a coker furnace for producing a coker-drum feed stream; and introducing a hydrogen-donor gas into either or both of the coker-furnace feed stream or the coker-drum feed stream.

Abstract: Partial upgrading processes can include thermal treatment combined with solvent deasphalting, and recycling of certain streams, to process bitumen feedstocks and produce a bitumen product. The thermal treatment can be done so that the feedstock is in liquid phase at conditions below incipient coking conditions. Solvent deasphalting can be done before or after thermal treatment depending on the configuration of the process. Subjecting the bitumen feedstock to a partial upgrading can facilitate viscosity reduction of the bitumen feedstock and can facilitate avoiding the need for the addition of an external source of hydrogen.
