Abstract:
The present invention relates to a method and system for recovering and processing a hydrocarbon mixture from a subterranean formation. The method comprises: (i) mobilizing said hydrocarbon mixture; (ii) recovering said mobilized hydrocarbon mixture; (iii) deasphalting said recovered hydrocarbon mixture to produce deasphalted hydrocarbon and asphaltenes; (iv) gasifying said asphaltenes in a gasifier to generate hydrogen, steam and/or energy and CO2; (v) upgrading said deasphalted hydrocarbon by hydrogen addition to produce upgraded hydrocarbon; and (vi) adding a diluent to said upgraded hydrocarbon, wherein said method is at least partially self-sufficient in terms of hydrogen and diluent.
Abstract:
A gasifier start-up method for a gasifier capable of preventing or inhibiting a temporary occurrence of black smoke when a gasifier is started-up. A gasifier start-up method for a gasifier, in which a gasifying agent and a solid carbonaceous fuel are supplied and gasified, includes a start-up burner igniting step of supplying a start-up fuel and oxygen-containing gas to a start-up burner and igniting the start-up fuel and oxygen-containing gas, under an inert atmosphere in which an inside of the gasifier around the start-up burner is filled with inert gas; and an oxygen-containing-gas supply adjusting step of adjusting the supply of the oxygen-containing gas such that combustion gas obtained after the combustion reaction of the start-up fuel and the oxygen-containing gas becomes the inert gas, which contains little oxygen.

Abstract:
An annular injector is described. The injector includes a first bayonet assembly and a second bayonet assembly each including a terminal end and a tip end. The second bayonet assembly is configured to be concentrically coupled at least partially about the first bayonet assembly. An outer diameter of the first bayonet assembly and an inner diameter of the second bayonet assembly vary at the tip end to define a first substantially annular nozzle. The first bayonet assembly includes a maximum outer diameter that is greater than a minimum inner diameter of the second bayonet assembly and at least a portion of at least one of the first bayonet assembly and the second bayonet assembly extends from the tip end to the terminal end. The injector includes a third bayonet assembly configured to be concentrically coupled at least partially about the second bayonet assembly to define a second substantially annular nozzle.
