Abstract

A fuel delivery system for a gas turbine engine includes 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 includes 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; and a water removal component disposed between the catalyst and the contactor, wherein the water removal component removes water from the stripping gas stream.
