Abstract

A method of fuel desulfurization comprises receiving fuel from a source of fuel in a gaseous phase and condensing the fuel in the gaseous phase in a fuel condenser to convert at least a portion of the fuel into a liquid phase. The method further comprises delivering the fuel in the liquid phase directly to a reformer and returning the uncondensed portion of the fuel in the gaseous phase to the source of fuel to inert the source of fuel.

First claim

What is claimed is:

1. A method of fuel desulfurization, comprising:
receiving fuel from a source of fuel in a gaseous phase by drawing the fuel in the gaseous phase from the source of fuel with a blower in communication with the source of fuel;
directing, by the blower, the fuel in the gaseous phase to a fuel condenser;
condensing the fuel in the gaseous phase in the fuel condenser to convert at least a portion of the fuel into a liquid phase;
delivering the fuel in the liquid phase to a reformer; and
returning an uncondensed portion of the fuel in the gaseous phase to the source of fuel to inert the source of fuel.

2. The method of claim 1 , wherein receiving fuel from the source of fuel in the gaseous phase further comprises:
receiving a source of input; and
generating, by a processor, one or more control signals for the blower fluidly coupled between the source of fuel and the fuel condenser to operate the blower based on the input.

3. The method of claim 1 , further comprising:
receiving a cooling fluid from a source of cooling media at the fuel condenser.

4. The method of claim 3 , further comprising:
receiving a source of input; and
generating, by a processor, one or more control signals for a cooling valve fluidly coupled between the source of cooling media and the fuel condenser to open the cooling valve based on the input.

5. The method of claim 1 , further comprising:
receiving the fuel in the liquid phase by a fuel collector, and directing, by the fuel collector, the fuel in the liquid phase to the reformer.

6. The method of claim 1 , wherein the condensing the fuel in the gaseous phase in the fuel condenser further comprises:
receiving a cooling fluid from a source of cooling media fluidly coupled to the fuel condenser.

7. The method of claim 6 , wherein the source of cooling media is an environmental control system onboard an aircraft.

8. The method of claim 6 , wherein the source of cooling media is a refrigerant.

9. The method of claim 1 , wherein the receiving fuel from the source of fuel in the gaseous phase further comprises:
receiving jet fuel in the gaseous phase from at least one of a wing-mounted fuel tank or center-mounted fuel tank of an aircraft, and
the returning the uncondensed portion of the fuel in the gaseous phase further comprises returning the uncondensed portion of the fuel to the at least one of the wing-mounted fuel tank or the center-mounted fuel tank to inert the at least one of the wing-mounted fuel tank or the center-mounted fuel tank.

10. A method of fuel desulfurization, comprising:
receiving jet fuel in a gaseous phase from at least one of a wing-mounted fuel tank or center-mounted fuel tank of an aircraft;
condensing the fuel in the gaseous phase in a fuel condenser to convert at least a portion of the fuel into a liquid phase;
delivering the fuel in the liquid phase to a reformer; and
returning an uncondensed portion of the fuel in the gaseous phase to the at least one of the wing-mounted fuel tank or the center-mounted fuel tank to inert the at least one of the wing-mounted fuel tank or the center-mounted fuel tank.

11. The method of claim 10 , further comprising:
receiving the fuel in the liquid phase by a fuel collector, and directing, by the fuel collector, the fuel in the liquid phase to the reformer.

12. The method of claim 10 , wherein the condensing the fuel in the gaseous phase in the fuel condenser further comprises:
receiving a cooling fluid from a source of cooling media fluidly coupled to the fuel condenser.

13. The method of claim 12 , wherein the source of cooling media is an environmental control system onboard an aircraft.

14. The method of claim 12 , wherein the source of cooling media is a refrigerant.

15. A method of fuel desulfurization, comprising:
receiving fuel from a source of fuel in a gaseous phase;
condensing the fuel in the gaseous phase in a fuel condenser to convert at least a portion of the fuel into a liquid phase;
delivering the fuel in the liquid phase to a reformer; and
returning an uncondensed portion of the fuel in the gaseous phase to the source of fuel to inert the source of fuel,
wherein the condensing the fuel in the gaseous phase in the fuel condenser further comprises receiving a cooling fluid from an environmental control system onboard an aircraft fluidly coupled to the fuel condenser.

16. The method of claim 15 , further comprising:
receiving the fuel in the liquid phase by a fuel collector, and directing, by the fuel collector, the fuel in the liquid phase to the reformer.
