Abstract: A fuel tank system is disclosed that includes a fuel tank and a first fluid flow path between a gas space in the fuel tank and outside of the fuel system. A gas separation membrane is disposed with a first side in communication with the first fluid flow path and a second side in communication with a second fluid flow path. A fluid control device is in communication with the second fluid flow path and is configured to provide fluid flow from the second fluid flow path to a liquid space in the fuel tank or to outside of the fuel system. A prime mover is disposed in communication with the second fluid flow path, and is configured to move fluid on the second fluid flow path from the second side of the separation membrane to the fuel tank liquid space or to outside of the fuel system.

Abstract: Disclosed is a fuel system with a fuel tank containing hydrocarbon fuel, a hydrocarbon fuel flow path in fluid communication with the fuel tank, and a gas separation pump disposed on the flow path. The gas separation pump has a pump housing with an inner wall defining a cylindrical internal cavity. The pump housing includes an inlet at a first axial position along the cylindrical cavity outer circumference, an outlet at a second axial position along the cylindrical cavity outer circumference, and a vacuum connection in fluid communication with the cylindrical cavity axis. A first impeller with an outer edge configured to sweep along the inner wall is axially disposed between the inlet and the outlet. A second impeller configured to eject liquid through the fluid outlet is axially disposed between the first impeller and the outlet.

Abstract: An on-board aircraft inert gas system includes a source of hydrocarbon, a source of gas comprising oxygen, and a first fluid flow path between the source of gas comprising oxygen and an inert gas output. A reactor is disposed along the first fluid flow path that reacts oxygen and hydrocarbon from the fuel tank gas space to produce an oxygen-depleted gas. A heat exchanger condenser removes some water from the oxygen-depleted gas. A water-permeable gas membrane separator receives the oxygen-depleted gas from the heat exchanger and outputs dried oxygen-depleted gas.
