摘要:
The invention relates to a process for utilizing the heavy liquid fractions resulting from oil refining, by combustion in a fluidized-bed chemical looping process. The process according to the invention is used to produce energy by completely oxidizing the heavy liquid feedstocks, while allowing direct capture of the CO 2 emitted in the combustion flue gases. The process according to the invention also enables a syngas to be produced.
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 CO 2 -concentrated fumes in order to enable CO 2 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).
摘要:
The invention relates to a combustion chamber that comprises a housing (1) including at least one fuel-injection means (2), at least one oxidant-injection means (3), and at least one means (5) for drawing the combustion fumes, wherein the housing (1) is in the shape of a tube having any cross-section and which is recurved and closed, while the fuel- (2) and oxidant- (3) injection means are provided on the housing (1) so as to be offset by an angle θ defined by each of the fuel- and oxidant-injection positions relative to the centre (C) of the housing, said angle being between 10° and 90°, and wherein the oxidant-injection means is a means for injecting an oxidant consisting of a gas having an oxygen content higher than 90%.
