  • Patent number: 11001762
    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.
    Type: Grant
    Filed: April 6, 2018
    Date of Patent: May 11, 2021

  • Patent number: 10011789
    Abstract: The invention provides a Fischer-Tropsch jet fuel refining process which has a jet fuel yield in excess of 60% by mass, said process including at least four of the following Five conversion processes: a. hydrocracking one or more of a FT kerosene and heavier material fraction and a C9 and heavier FT Syncrude fraction; b. oligomerising an FT syncrude fraction including hydrocarbons in the range C2 to C8; c. hydrotreating one or more of an FT syncrude fraction, a product from process b., and an alkylated FT syncrude fraction; d. aromatizing one or more of an FT syncrude fraction including hydrocarbons in the range C2 to C8, a product from process a., a product from process b, a product from process c., and a product from an aromatic alkylation process; and e. alkylating one or more of an FT syncrude fraction including hydrocarbons in the C2 to C6 range, a product from process b., and a product from process d.

  • Publication number: 20140138287
    Abstract: A process for upgrading oil including optionally pre-treating a heavy oil including at least one dissolved gas, asphaltenes, water, and mineral solids; reducing at least one dissolved gas content from said heavy oil, optionally further reducing water content from said heavy oil; adding a paraffinic solvent to said heavy oil, at a predetermined paraffinic solvent:heavy oil ratio, facilitating separation of asphaltenes, water, and mineral solids from the heavy oil resulting in a de-asphalted or partially de-asphalted oil (“DAO”)-paraffinic solvent stream, comprising a low asphaltenes content DAO-paraffinic solvent stream and an asphaltenes-mineral solids-paraffinic solvent-water slurry stream; optionally separating the paraffinic solvent and water from the asphaltenes-mineral solids-paraffinic solvent-water slurry stream; optionally separating the DAO-paraffinic solvent stream into a paraffinic solvent rich stream and a DAO stream; and optionally adding diluent to the DAO stream resulting in transportable oil.
