Abstract
A fuel stabilization unit includes a fuel inlet and outlet, an oxygen permeable membrane and a vacuum source. The vacuum source employs an ejector and a high pressure fluid to generate an oxygen partial pressure differential across the membrane. A fuel deoxygenation system includes a fuel stabilization unit and a vacuum source. The fuel stabilization unit has a fuel flow path, a vacuum chamber and an oxygen permeable membrane separating the fuel flow path and the vacuum chamber. The vacuum source employs an ejector and a high pressure fluid to reduce pressure in the vacuum chamber to generate an oxygen partial pressure differential across the oxygen permeable membrane. A method for deoxygenating a fuel includes delivering a high pressure fluid to an ejector, generating an oxygen partial pressure differential across an oxygen permeable membrane using only the ejector and removing oxygen from the fuel using the oxygen partial pressure differential.
