Classification: CPC F  B  Y | IPC B  F

Claim 0:
1. A fuel delivery system for a gas turbine engine comprising:
a fuel source;
a draw pump downstream of the fuel source for generating a liquid fuel flow from the fuel source;
a main fuel pump downstream of the draw pump; and
a fuel oxygen reduction unit downstream of the draw pump and upstream of the main fuel pump, the fuel oxygen reduction unit comprising:
a stripping gas line;
a contactor in fluid communication with the stripping gas line and the draw pump for forming a fuel/gas mixture, wherein the contactor receives an inlet fuel flow from the draw pump;
a separator in fluid communication with the contactor, the separator receives the fuel/gas mixture and separates the fuel/gas mixture into an outlet stripping gas flow and an outlet fuel flow at a location upstream of the main fuel pump;
a catalyst disposed downstream of the separator, the catalyst receives and treats the outlet stripping gas flow, wherein a stripping gas stream flows out the catalyst;
a water removal component disposed between the catalyst and the contactor, wherein the water removal component removes water from the stripping gas stream; and

a boost pump downstream of the separator and upstream of the contactor, wherein the separator and the boost pump are both coupled to, and driven by, an accessory gearbox of the gas turbine engine.
