A fuel oxygen conversion unit includes a contactor; a fuel gas separator, the fuel oxygen conversion unit defining a circulation gas flowpath from the fuel gas separator to the contactor; and an isolation valve in airflow communication with the circulation gas flowpath for modulating a gas flow through the circulation gas flowpath to the contactor.

Fuel oxygen conversion unit with valve control

An engine includes a stripping gas source, a combustion section, and a fuel oxygen conversion unit positioned upstream of the combustion section, the fuel oxygen conversion unit defining a stripping gas flowpath in airflow communication with the stripping gas source. The fuel oxygen conversion unit includes a contactor defining a fuel inlet, a gas inlet in airflow communication with the stripping gas flowpath, and a fuel gas mixture outlet; and a fuel gas separator defining a fuel gas mixture inlet for receiving a fuel gas mixture from the contactor, a liquid fuel outlet, and a stripping gas outlet; wherein the stripping gas flowpath receives substantially all of a stripping gas flow therethrough from the stripping gas source and provides the stripping gas flow to the contactor.

Fuel oxygen conversion unit

An engine includes a combustion section and a fuel delivery system in fluid communication with the combustion section for providing fuel to the combustion section. The fuel delivery system includes a fuel oxygen reduction unit defining a circulation gas flowpath. The fuel oxygen reduction unit includes a gas oxygen reduction unit positioned in the circulation gas flowpath for reducing an oxygen content of a flow of stripping gas through the circulation gas flowpath and a pre-heater positioned in thermal communication with the circulation gas flowpath upstream of the gas oxygen reduction unit.

Fuel oxygen reduction unit

A fuel oxygen conversion unit includes a stripping gas flowpath for a vehicle or an engine of the vehicle. The fuel oxygen conversion unit includes a stripping gas boost pump positioned in airflow communication with the stripping gas flowpath for increasing a pressure of a flow of stripping gas through the stripping gas flowpath; a contactor defining a stripping gas inlet in airflow communication with the stripping gas flowpath, a liquid fuel inlet, and a fuel/gas mixture outlet; a fuel gas separator defining a fuel/gas mixture inlet in fluid communication with the fuel/gas mixture outlet of the contactor, a stripping gas outlet, and a liquid fuel outlet; and a connection assembly mechanically coupling the stripping gas boost pump to the fuel gas separator, the connection assembly having a speed change mechanism such that the stripping gas boost pump rotates at a different rotational speed than the fuel gas separator.
