INTEGRATED SEQUENCE OF METHODS FOR EXTRACTING AND PROCESSING EXTRA-HEAVY OR BITUMINOUS CRUDE OIL WITH CO2 TAPPING

摘要

The invention relates to a method for preparing synthetic crude oil from a heavy crude oil field, said method including: (a) extracting the heavy crude oil using a steam technology; (b) separating the extracted crude oil from the water; (c) separating the crude oil into at least one light fraction and one heavy fraction; (d) converting the heavy fraction into a lighter product and a residue; (e) optionally partially or totally hydroprocessing the converted product and/or the light fraction(s) obtained during the separation (c); (f) burning and/or gasifying the conversion residue in the presence of metal oxides during at least one chemical loop cycle producing CO2-concentrated fumes in order to enable CO2 tapping, wherein the optionally hydroprocessed converted product and the light fraction(s) from the separation constitute said synthetic crude oil, said combustion enables the generation of steam and/or electricity, and the gasification enables the generation of hydrogen, the steam and/or electricity thus generated being used for the extraction (a), and/or the electricity and/or the hydrogen thus generated being used for the conversion (d) and/or the hydroprocessing (e).
